Standard Air Knife
The Standard Air Knife is available in ten standard lengths of 3", 6", 9", 12", 18", 24", 30", 36", 42" and 48" (76, 152, 229, 305, 457, 610, 762, 914, 1067 and 1219mm). This measurement refers to the airflow length. The overall length is 1" (25mm) longer. Special lengths up to 48" (1219mm) and unlimited system lengths are available. Any number of Standard Air Knives may be installed across a given area.
Magnetic bases with Flexible Stay Set Hoses™ are also available for smaller Standard Air Knives. Please contact our factory.
The Standard Air Knife can be mounted using the Universal Air Knife Mounting System. It can also be supported by the compressed air pipe.
Compressed Air Inlets:
A Standard Air Knife has compressed air inlets on each end. Lengths 24" (610mm) and longer should be supplied with compressed air at each end to maintain uniform airflow.
The use of clean air is essential. Kits include an automatic drain filter with a 5 micron filter element that is sized properly for flow.
Materials of Construction:
The Standard Air Knife is available in either aluminum or stainless steel construction.
A pressure regulator on the compressed air supply provides infinite control of flow, force, and air consumption. Kits include a pressure regulator that is sized properly for flow.
A Standard Air Knife has a .002" (0.05mm) gap setting. This gap is set with a shim positioned between the cap and body of the Standard Air Knife. Force and flow through the Standard Air Knife may be easily increased by adding shims to open the gap. Standard Air Knife Kits include a shim set (three additional shims). Shim sets for aluminum Standard Air Knives include a .001" (0.03mm) (amber color), .003" (0.08mm) (green color) and .004" (0.10mm) (tan color) plastic shims. Shim sets for stainless steel Standard Air Knives include (3) .002" (0.05mm) thick stainless steel shims.

Universal Air Knife Mounting System
The Model 9060 Universal Air Knife Mounting System is used to provide secure, precise positioning for any of the EXAIR Air Knives. It can be mounted on either the top or bottom of most Air Knives (Super Air Knife, Standard Air Knife and Full-Flow Air Knife). The Universal Air Knife Mounting System has a durable, stainless steel construction that is suitable for a variety of industrial applications.

Electronic Flow Control
EXAIR's EFC is an electronic flow control that dramatically reduces compressed air costs by turning off the compressed air when no part is present. This minimizes compressed air use for blow off, drying, cooling, conveying and static elimination operations. The EFC combines a photoelectric sensor with a timing control that limits compressed air use by turning it off when no part is present. Click here for more information.
