Slitter Knife Dust Capture Hood

This innovative solutions ensures dust is captured at the source to ensure clean stock results.

Solution Overview

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.
