Air knives, Air guns / Cannons & Anti-static bars
An air knife is a compressed air-filled chamber with converging route to a controlled output slot. This provides a uniform velocity distribution across the entire length of the blade. Due to the Coanda-effect at the same time ambient air is sucked in with the primary air flow. Hereby an even more powerful secondary air flow is obtained.
The strong laminar flow of the air knife use include: to remove moisture, viscous layers to spread, dust and waste removal and separates two spaces / process conditions.
An air cannon operates in the same way as an air knife, with the difference that there is a strong cone-shaped air flow is generated.
One must pay particular attention to the control of dust and liquid which will be removed by the air knife. All health and safety aspects should be observed carefully. Liquid material which is removed, may form a spray. Due too air turbulence spray may be deposited on unwanted places. Observe the correct shielding and possibly of extraction of dry and liquid substances released.
Because air knives contain no moving parts, they ask little maintenance. However, the air supply must be clean, by the use of appropriate filters. The connecting pipe work should be dimensioned in the right way in order to minimize pressure losses.
