Zigzag Density Separation
The zigzag separation system can be installed at a conveyor junction and is typically applied to clean the unwanted contaminants and debris from the 0-100mm material stream. The contaminated material discharges the feed conveyor into a zigzag cascade enclosure where the material falls through an upwards travelling air stream and density separation occurs.
Contaminated material is fed into the zigzag system via a variable speed rotary valve. The falling material cascades over a series of zigzag baffles ensuring efficient removal of debris which is collected via a material separator for further processing/disposal. Variable air volumes and adjustment dampers also ensure minimal loss of valuable recyclable material to provide maximum flexibility and highly efficient cleaning of the material. The Zigzag Separation System is available in a range of sizes to suit your process and material throughputs.
Common applications include, but are not limited to:
Trommel Fines
DMR (Dry Mixed Recycling)
Glass Recovery/Cleaning
MSW (Municipal Solid Waste)
SRF (Solid Recovered Fuel)
RDF (Residue Derived Fuel)
Gypsum/Plasterboard
Plastic

Trim Master Bagging Unit
The Trim Master Bagging Unit is a cost effective, flexible, trim and dust extraction unit designed to collect waste material from a single production machine and deliver it to a locally mounted trim bagging station, where the waste is collected in polythene bags for manual disposal.
Usually found working in conjunction with digital printing machines where waste is generated from a three-knife trimmer, slitting station or similar, this hugely versatile solution, offers ultimate flexibility for low volume waste applications, without incurring the costs associated with a centralised trim extraction solution.
Incorporating all the usual design cues from our centralised waste and trim solutions, the trim master bagging unit consists of a range of trim grade ductwork, waste handling fan, specially engineered waste and dust collection plenum, disposable polythene waste bag for the waste trim and disposable exhaust air filter media, neatly packaged together in a cost-effective solution to suit many low volume applications.
We offer a range standard models designed to suit a range of paper, carton board and corrugated trim applications, air volumes and operating conditions.
The Impact Trim Master Bagging Unit and Label Matrix Master are manufactured in the UK with spares and support readily available if required.
Precision Trim Cutter
The precision trim cutter is a compact and versatile precision cutting unit used with Impact's label matrix extraction systems, among others.
The trim cutter unit is designed to offer precision cutting of a wide range of continuous materials. It enables continuous web manufacturers, slitters and converters to remove edge trim from production. It can cut cleanly through very thick materials like carpet edge trim. At the other end of the scale it can deal with extremely tough plastic film, foils, fabrics, filaments and non-woven materials down to as little as 12μm thin.
Two base models are available in the range. A model 78 series unit is ideally suited to materials being conveyed in ductwork up to 150mm in diameter. The model 811 series cutter is most suitable for larger volumes and heavier materials.
The advantages of the 78 and 811 series cutter are explained below:
Rotating fly knives are cylindrically ground in housing to ensure uniform clearance across the complete width of the bed knife. Proprietary milling process matches fly knives to rotor notches for secure, positive location and retention. Available in standard AISI-D2 tool steel or in optional tungsten carbide.
Cutter Exchange Service
At Impact we realise the importance of keeping your cutter running efficiently. From time to time, depending on the application, you will need to have the knives re-sharpened and set or the complete cutter exchanged.
Re-sharpening:
Worn or damaged knives must always be re-sharpened before adjusting cutting clearances.
Procedure:
The re-sharpening and re-setting of the knives is a very precise procedure with clearances being set as little as 0.00025” (6.35µ) and must only be carried out by a skilled engineer who is familiar with the 78/811 Series and who has been suitably trained in the use of surface and cylindrical grinding. The knives can not be precision set to the required accuracy unless they are fitted into the cutter unit, they cannot be removed, sharpened and then re-fitted. With this in mind we strongly recommend you contact us and we will arrange for the necessary work to be carried out.
Exchange:
Contact us when your knives are ready to be re-sharpened and set. We will ask for a purchase order number and then arrange for a re-furbished, serviced, replica cutter to be despatched to you within 1 or 2 days (dependent on availability). When you receive the cutter it should be swapped with the worn cutter, this ensures that you will only suffer minutes of downtime and maximum operating efficiency will be restored. The worn cutter must then be returned to us within 14 days.

Material Handling Fan
Impact's chopper fan is a purpose designed, heavy duty, material handling fan fitted with hardened steel cutting blades.
Its function is to provide the required conveying air volume and pressure to efficiently transport the waste material through the system from the production machines to the material separator unit. It has a reinforced, dynamically balanced, self-cleaning steel impeller, proportioned for maximum aerodynamic efficiency but with the added capability to chop any large pieces of waste into more manageable pieces.
The chopper fan is equipped with a heavy duty, adjustable spring loaded inlet assembly ensuring the correct chopping action occurs during operation and to provide protection from surge loads. The fan is driven from a compact overhead or base-mounted drive motor arrangement (depending on size) via a variable speed v-belt transmission, all assembled and tested prior to delivery.
Plastic
Impact has vast experience in providing systems to separate and extract plastics of varying forms, from removing plastic bags and films from the waste stream and baling to an efficient and effective solution to remove dust, debris and fibres from plastic granules/flakes to provide a more valuable product for recycling.
With increasing pressure to reduce waste going to landfill, it is more important than ever to ensure that recyclable materials are recovered from the waste stream. Our systems ensure that these materials are recovered and are successfully doing so in many recycling facilities around the world every day, saving thousands of tonnes of recyclable materials ending in landfill.
Impact continues to provide support to the recycling industry with air based technology to enhance the operations of any materials recycling facility or waste sorting centre.
The Impact Film Vacuum System removes plastic bags and films from the waste stream and bales it with our screw compactor system. Our Zigzag Separation Systems provide an efficient and effective solution to remove dust, debris and fibres from plastic granules/flakes to provide a more valuable product for recycling. The Impact Pneumatic Conveying System seamlessly transports plastic bottles and containers through your facility via a ductwork system to external storage containers or bunkers.
Our systems will recover plastics such as WEEE, PET, LDPE, HDPE, PP, PS & PVC.
Airknife Waste Separation
The Airknife's main function is to remove low value fractions from the material stream. Typically installed at a conveyor junction, the Airknife consists of an input air volume channelled through an adjustable nozzle, working in conjunction with an extraction hood, all mounted inside a single enclosure.
The Airknife is employed to remove lightweight unpickable items such as paper, plastic and foil from the material stream. The input air creates a high velocity airstream through which the falling material has to travel. The lighter material fractions are blown or separated from the falling material and are captured by the extraction hood and conveyed away. The heavier material is unaffected by the incoming airstream and falls onto the conveyor below.
The Impact Airknife solution can be adopted and applied to a wide variety of material streams including, domestic comingled recyclables and C&D recycling operations.
Air Drum Separator (ADS)
The ADS is a specially adapted air knife separator unit working in conjunction with a rotating drum and is designed to separate a wide variety of materials based on density, shape and aerodynamic properties. Used for separating a mixed stream of material into heavy and light components.
This is done using a forward upward facing air knife nozzle mounted at the end of a material in-feed conveyor. Mixed material falling from the in-feed conveyor then passes through the high velocity air stream and is either carried over the drum or is unaffected and falls in front of the drum.
The use of the drum is the latest development in material separation technology and utilises fluid dynamics principles to greatly improve the efficiency of the air stream once it has left the confines of the air nozzle, resulting in greatly improved separation.
Advanced Separation Technology
- Separation of material based on density and shape
- Very high hourly throughput levels achievable
- Fully adjustable airflow controls via electronic fan speed controls
- Outstanding results to significantly improve the separation of the material stream
- Best suited for: C&D, C&I, WEEE, MBT, RDF/SRF, MSW, ASR and many more
- Few wear items, low maintenance and highly reliable
- Available in three standard widths, 900mm, 1500mm and 2000mm (other configurations available on request)
Zigzag Air Classifier
Impact recognises the industry requirements of ensuring a high-quality waste stream, so has further engineered a successful separation solution which greatly improves the separation of valuable recyclable materials while providing the operator with a low maintenance and hassle-free system.
Combining our highly skilled in-house engineering team, 3D modelling software and working in conjunction with our carefully selected external supplier base, the ZAC800 boasts impressive resistance to abrasive materials, less moving parts and the very latest fitration technology, whilst maintaining its exceptional separation efficiency.
Utilising density separation by the power of air, the ZAC800 is specially engineered for processing of glass rich or highly abrasive sub 100mm material streams, constructed from carefully selected materials ensuring exceptional durability. The Zigzag cascade enclosure includes hardened chromium cast plates to greatly reduce wear from glass.
Advanced Separation Technology
Zigzag material separation technology is used to separate light weight material particles from heavier particles by cascading the mixed in-feed material through an upwards travelling air stream inside a zigzag shaped enclosure.
An upwards travelling airstream collects the lightweight material particles, allowing separation or grading of feedstock. Heavier material particles are not affected by the airstream and discharge at the bottom of the zigzag enclosure.
The zigzag air classification technology is ideally suited to low moisture, free flowing, consistently sized material particles up to approximately 60mm in size, where there is a noticeable difference in the product density or weight (i.e. separation of lightweight paper, film, dust and plastic from heavier stone, glass or metal).
Cyclone - Dust Control
Impact offers a range of medium and high efficiency cyclones that are ideal for material pre-separation applications where small or fine material particles need to be removed from the conveying air stream prior to fine dust filtration.
Material separation efficiencies of typically above 90% can be achieved for paper dust (depending on particle size and density).
Material is discharged via a vortex breaker or optional rotary valve.
Typically constructed from high grade mild steel 2-3mm thick (depending on model selected), fully welded construction and finished in high grade paint.
A wide range of models are available to suit different air volumes and material types.
Edge Trim Extraction System
Removing edge trim from corrugators or high speed slitting stations in heavy weight or thick material applications such as corrugated board or heavy weight laminated edge trims, can often be challenging, especially when dealing with wide edge trims travelling up to 1500 meters per minute. It is critical to ensure the position and specification of the equipment designed to receive and process this type of material is robust and correctly engineered.
Through working with the leading machinery manufacturers and blue chip corrugated board producers and converters, we have installed many reliable systems. At the heart of the system is a heavy duty chopper fan positioned to reduce the difficult continuous edge trims into more manageable and easy to convey pieces.
Dust Control Systems
Impact Air Systems offer a wide range of dust control solutions to meet the vast range of applications faced in modern day production environments.
Our robust range of solutions, developed over many years, allows us to confidently manage your dust issue. Whether you require a simple supply and connect dust bagging unit or a custom designed and professionally installed dust filtration/air recycling system, we are able to help.
We have supplied and installed centralised dust control systems in a wide range of industries such as power stations, waste management sites, commercial printing, corrugated board manufacturers, furniture manufacturers, packaging and conversion facilities, foundries, textile manufacturers and many more.
Working to standards and directives
Our engineers are qualified to BOHS P601 and P602 and work strictly to HSG258, COSHH 2002 regulations and Workplace Exposure Limits EH40 (UK regulations). Our systems are designed to help you to ensure compliance with ATEX 2014/34/EU and NFPA standards, supporting employers responsibilities to carry out DHA (Dust Hazard Analysis), where applicable. (All dust collection systems in the US are required to have a DHA no later than October 2018, this is one of the most important changes to NFPA standards in recent history). Read more here.
Dust dangers
• Fire/explosion - Combustible dusts present an explosion hazard when suspended in certain conditions which can result in catastrophic damage.
• Occupational health issues - as well as creating an unpleasant working environment for staff, some types of dust can cause respiratory allergies, infection and long term health problems such as asthma and chronic obstructive pulminary disease.
• Maintenance issues - An excessive build up of dust can get into moving parts and create problems with the efficiency of operational equipment.
Slitter Knife Dust Capture Hood
The Impact slitter knife dust capture hoods combine high velocity air flow design and electrode eliminating electrostatic charge techniques, resulting in impressive dust particle removal at source compared to conventional dust removal hoods.
Nuisance dust emissions created by the slitting process can result in:
• Poor print quality
• Maintenance problems relating to motors and bearings
• Fire hazard
• Health and safety issues
• Production downtime
This clever technology utilises a high velocity air flow in excess of 60m/sec in combination with an internal “venturi effect” parallel channel, streaming against the web direction, resulting in levels of dust removal efficiency unachievable with conventional slitter hood designs. The slitter knife hood can achieve dust removal efficiency of 95% > 35 micron ensuring the cleaniliness of sheeted stock and minimises 'hickies' (dust related defects) at the printing press.
The Impact range of slitter knife hoods operate with low extraction volumes making them suitable for retrofit applications. The hoods can be combined with web cleaning equipment and electrostatic charge elimination equipment, providing a comprehensive solution.
Tubular Reverse Jet Filter
Dust is efficiently removed from the conveying air using anti-static polyester needle felt tubular bags. An electronic sequence controller initiates a pulse of compressed air which momentarily reverses the flow of air through the filter bag to release the dust into the discharge hopper below.
Optional pressure driven sequence controllers allow on demand cleaning facility when the filter pressure has reached a specific level, ensuring the filter bags are only cleaned when needed, saving expensive compressed air.
Filters are available to suit a wide range of dust applications and air volumes. The Impact reverse jet filter complies with all relevant Health & Safety requirements and will clean the air to a very high quality, easily achieving HSE and COSHH requirements. All filters comply with the ATEX directive (2014/34/EU).
Pneumatic Transfer Lines
The pneumatic transfer system is utilised in many recycling operations allowing pre-separated dry materials such as plastic containers, aluminium and steel tins and beverage cans to be conveyed through a range of ductwork directly to storage bunkers or balers using the most direct route, eliminating the need to utilise conventional belt conveyors, which can often take up valuable floor space.
Typically receiving material directly from Eddie current separators, magnetic separators or optical sorting equipment, this solution offers ultimate flexibility to most recycling facilities.
Material is fed into the system via a Venturi style receiving hopper and transfer box, where it then falls into a moving airstream provided by a high efficiency fan and is blown via a range of ductwork directly to the storage bunker or baler.
The pneumatic transfer system has proven to be a highly valued addition to the material recovery facility offering designers and operators maximum flexibility.
Film Vacuum System
The system consists of a series of specially designed material collection hoods which are typically mounted in the ceiling of the sorting cabin above the waste belts. The operator simply offers the film or plastic to the hood and it then automatically sucked away.
The unique internal ‘Jetcone’ hood design uses a closed loop system to minimise operational noise levels and the amount of air withdrawn from the sorting cabin. Conveying air, used to transport the material, is recycled back through a return air system to significantly reduce the cabin make up air requirements. A series of collection hoods can be connected together via a range of ductwork, meaning all material is transported to a single point within the MRF, eliminating the need to duplicate material storage bunkers to match each hand picking location.
Conveyed material is typically fed directly into a bale press to reduce material volumes, minimising labour and transport costs. The material is separated from the airstream via a specially adapted Impact rotary material separator and reverse jet filter system. The Impact Film Vaccum System has proven to be a highly valued addition to the domestic waste recycling process, offering MRF designers maximum design flexibility and improved segregation of recyclables.
Screw Compactor
A valuable addition to any Film Vacuum System, this simple design allows collected material to be compressed into an expanding plastic bag to produce a ‘sausage’ like bale. A single screw auger, discharge tube and retaining ring provide a simple yet highly reliable, cost effective solution to reduce bulky material into manageable volumes.
Briquetting Systems
Designed to substantially reduce the volume of nuisance dust collected via dust filtration, this extremely versatile unit can be easily integrated into the system design allowing dust volume reduction levels of 20:1. No longer is it necessary to manually handle large sacks of waste dust collected during filtration, instead the material is efficiently converted into manageable high density briquettes, reducing storage and handling requirements.
Dust is received by the collection drum and when the unit is activated by a level probe, it is fed by a dosing paddle into the compression chamber. Hydraulic rams convert the loose material into the final shape before ejecting the finished product.
The Impact dust briquetting system is the obvious choice for high dust volume applications helping to reduce labour and material handling. In addition, this waste material often has a very high calorific value and (depending on the source) can often be used as a fuel source in a number of waste to energy facilities.
Air Separator Assembly
The material separator's main function is to separate the waste material collected by the system from the conveying air stream. The separator assembly consists of a perforated screen plate, inclined downwards at an angle inside metal housing.
Air and material enter through an inlet in the housing at the top of the perforated screen plate and are accelerated downwards. An inlet aerofoil pre-set during commissioning, ensures the perforated screen is self cleaning and remains free from material to maintain reliable operation.
The conveying air passes through the screen plate and exits the separator through an outlet port either in the top or the back of the unit. Material travels down the full length of the screen plate and leaves the separator through an outlet in the bottom. The material then exits the separator unit under the action of gravity alone.
We offer a range of size and screen types to suit a vast range of material and applications (between 3,500 and 75,000 cubic metres per hour).
• Replaceable self cleaning separator screen
• Compact size
• High air handling capacity
• Puncture resistant screen plates
• Fully sealed, dust tight
• Adjustable regulating aerofoil
• Material discharge via a non leaking rotary valve
• Tolerant to variations in system air volume and pressure
• Material throughputs up to 25 tonnes per hour
• Gearbox adjustment of inlet aerofoil
• Available to suit a range of different materials
Industrial Ventilation Systems
Impact offer industrial ventilation to a wide range of industries including paper mills, packaging production, print production, EFW sites, materials recycling facilities and many more.
Recycling Industry
Many recycling applications such as MSW, RDF & SRF waste contain a high percentage of organic material which starts to decompose within the recycling facility. Heat created by shredding and general processing add to the issue.
In the extremes of cases the ambient internal temperature can increase by as much as 10 degrees celsius per hour of operation. This results in a gradual build up of moisture content within the air which condenses, particularly at high level. This moisture release can cause corrosion damage to the building and valuable equipment within the facility, as well as creating a very unpleaseant working environment.
Impact’s ventilation systems remove the moist, warm air and replace it with a supply of fresh air to substantially reduce temperatures, moisture levels and unwanted odours from the processing facility.
The solutions offered can range from simple wall/roof mounted extraction fans and make up air grilles to complex central ductwork and filter systems.
Body Maker Oil Mist Extraction
The Impact oil mist extraction solution offers a cost effective and reliable method of removing unwanted oil mist vapour from processes such as body making presses within the beverage can production industry or frying within the food industries.
Incorporating a central ductwork system, the system collects and conveys the oil mist vapour away from individual or multiple production processes for recovery providing a cleaner and healthier working environment.
Specialist collection hoods and a fully welded ductwork system ensures a leak free operation and a three stage filtration process efficiently collects and separates the oil mist from the conveying air stream, allowing the oil to be recovered and reused or recycled.
High efficiency variable speed fans provide the air stream and extremely high air quality emissions can be achieved using second stage HEPA or carbon filtration
Rotary Material Separator
The rotary separator replaces much bulkier cyclone or static screen separators. The design consists of a large diameter rotary valve coupled with a specially engineered heavy duty perforated screen combined within a single enclosure.
The screen design incorporates aerodynamic principles as well as a wiping action to ensure efficient, trouble free operation. This clever design guarantees waste separation from the conveying air, even with high waste loads, without the need for variable/adjustable inlets vanes or balance fans with Volume Control Dampers. A slowly rotating six-bladed star shaped rotor fitted with heavy duty wear resistant rubber seals forms a physical barrier, forcing the conveying air through the screen. The rubber seals provide a wiping action to the perforated screen ensuring it remains free from debris to maintain reliable operation.
The rotary separator has been engineered to withstand the demanding conditions expected in a variety of different applications. Constructed using heavy gauge welded steel construction, finished in high quality paint. We offer a range of four models designed to suit the vast range of materials, air volumes and operating conditions.
Factory Ventilation and Cooling
Extracting high volumes of process air from buildings results in the ingress of makeup air through doorways, windows etc.
This uncontrolled form of ventilation can lead to quality, environmental and housekeeping issues. Impact Air Systems provide energy efficient ventilation systems incorporating, if necessary, the latest adiabatic cooling technology tailored to suit individual factory requirements. Conditioned make up air is introduced at low level through external air input unit.
Using the principle that warm air rises, roof mounted filter plenum units enable the hot air within the factory to be exhausted to atmosphere. An intelligent control system constantly monitors the conditions in the factory and ensures that the correct volume, temperature and humidity of air is being supplied.
Process Exhaust Stacks
Hot gases, solvent vapour or fumes created by the production processes need to be discharged outside the building to atmosphere to ensure the maintenance of a safe and healthy working environment. Impact Air Systems supply and install a range of exhaust solutions designed to suit individual requirements.
IBO Conveyor Fume Extraction
The strong fumes generated by the cans as they travel between the lacquer sprayers and the IBO create an uncomfortable working environment. By installing an enclosure around the conveyor and connecting it to an extraction system, the fumes are contained and exhausted safely to the atmosphere.
Lacquer Sprayer Dust Extraction
Impact offer a highly efficient and fully certified spray powder and conveyor fume extraction system to eliminate unwanted odours and dangerous explosive overspray from the lacquer that is applied to the internal surface of the beverage can. Over spray from the lacquer spray application is efficiently extracted along with the solvent fumes emitted from the transportation conveyor to the IBO.
Explosion rated ductwork conveys the spray dust and fumes to a fully automatic reverse jet filter assembly. This (ATEX compliant) filter unit provides primary recovery of the dust and includes vertical discharge explosion relief panels and discharge chute allowing filtration to be located in close proximity to the spray process.
A second stage filter followed by a third stage absolute filter ensures a cleaning efficiency of above 99.9% is achieved. The conveying air stream is provided by a high efficiency centrifugal fan equipped with spark minimizing features which is installed on the clean side of the filtration system.
Paper Trim Extraction from Digital Print
Impact Air Systems have been providing trim extraction systems for nearly 30 years in a huge variety of applications and removing waste continuous edge trim generated from the modern digital printing presses is no exception.
Material is usually discharged from the digital press in a continuous ribbon form from both sides of the web and the central trim between copies needs to be collected from the press. Our simple, yet effective approach allows multiple machines to be connected to a central waste removal system, keeping the production area free from waste and potentially generating revenue from the recyclable waste paper.
High Level Structures and Access Platforms
We can provide a high-level access structure to allow safe and easy access to all the key areas of the system, including the rotary air lock and separator unit.
Due to our clever design our engineers are able to offer a range of access structures to suit your budget and operational requirements. We offer a light weight aluminium structure which can be incorporated into the design of the compactor / baler drop chute eliminating the need for floor mounted supports. This method reduces overall cost but ensures operators have safe access to waste handling equipment during maintenance.
Acoustic Insulation
With today's stringent noise regulations becoming even more demanding, we can offer a range of acoustic solutions for your waste extraction plant.
The acoustic enclosure for the waste handling fan is an ideal method of minimising noise transmitted by the fan, whilst allowing easy access for maintenance and repair.
For reducing noise transmitted through the ductwork, Impact can offer inlet and outlet silencers which can be applied to the material handling fan and machine pick up points.
