De-ionisation air knives reduce costs and minimise rejects

28 September 2014

Dust contamination is a huge problem in many areas of industry - especially where the product needs to be painted, decorated or laminated. Rectifying dust problems can have very large associated costs.

With operating cost savings of up to 70 percent and 50 percent greater efficiency compared to competitive solutions, Air Control Industries’ ‘De-ionisation Air Knives’ offer major benefits to users across industry. In addition, there is the resulting significant benefit of fewer rejects due to surface imperfections on finished products.

ACI’s De-ionisation Air Knives are based upon the company’s standard units which are used for cleaning, cooling and drying operations, but have a powerful ionisation bar attached to ionise delivered air to neutralise static charges for more effective cleaning.

The blower (typically between 5.5 and 7.5kW power) produces a high volume of air which exits from the air knife in a fast laminar flow (i.e. 110m/sec) at a pressure of around 7 Bar.  This ensures particles such as swarf and dust are removed effectively with the electrostatic charge neutralised to prevent re-attraction.

De-ionisation Air Knives are also available in a range of standard lengths up to 3,000mm but custom-engineered units can be supplied. All can be supplied as ‘EX’ units for hazardous environments. Additionally there is a complete range of accessories available including filters, pipework, flow valves, silencers, acoustic enclosures and remote monitoring systems.
