Full-Flow Air Knife

Catalog Request Full-Flow Air Knife Specifications

The Full-Flow Air Knife is available in eight standard lengths of 3", 6", 9", 12", 18", 24", 30" and 36" (76, 152, 229, 305, 457, 610, 762 and 914mm). Special lengths up to 36" (914mm) and unlimited system lengths are available.

Magnetic bases with Flexible Stay Set Hoses are also available for smaller Full-Flow Air Knives. Please contact our factory.

Mounting:
The Full-Flow Air Knife can be mounted using the Universal Air Knife Mounting System. It can also be supported by the compressed air pipe.

Compressed Air Inlet(s):
A Full-Flow Air Knife has the compressed air inlet(s) on the rear. Inlets are available on each end at a small additional charge, however, they are not recommended for applications where uniform flow across the length is required.

Filtration:
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 Full-Flow Air Knife is available in either aluminum or stainless steel construction.

Regulation:
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.

Shim Sets:
A Full-Flow Air Knife has a .002" (0.05mm) gap setting. This gap is set with a shim positioned between the cap and body of the Full-Flow Air Knife. Force and flow through the Full-Flow Air Knife may be easily increased by adding shims to open the gap. Kits include a shim set. Shim sets for aluminum Full-Flow 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 Full-Flow Air Knives include (1) .002" (0.05mm) thick stainless steel shim.

Universal Air Knife Mounting BracketUniversal 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 ControlElectronic 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.
