Installation
Air Supply
Clean, dry compressed air is required. The volume and speed of the ionised air output varies directly with
the pressure of the incoming compressed air - a pressure regulator should be sited close to the Air Knife so
that the pressure can be reduced to achieve the desired ionised air output with the minimum of air
consumption.
The object to be cleaned / neutralised should be as close as possible so that the air pressure can be
reduced for economical operation. Use a solenoid, or other switch to control the air to blow only when it is
needed. The electrical supply can run continuously.
Hi-flex cable is made to a high specification, but all HT cables must be treated carefully.
Sharp bends will damage the insulation and lead to breakdown. It is very important
that the cable is not bent more than a 50mm diameter (see sketch).
The fittings on the Air Knives are 1/4 BSP.
For sizes up to 500mm connect the air supply to one air entry on the Air Knife. For sizes over 500mm
connect the air to two air entries on the Air Knife to ensure uniform air velocity along the length of the Air
Knife, as shown:
It is important that the air supply pipe work is correctly sized to allow the required amount of compressed
air to reach the Air Knife. If the Air Knife is starved of air it will not work correctly. The consumption of air
depends on the pressure of the incoming compressed air. Typical air consumption per 25mm of Air Knife
is:
