Full-Flow Air Knife

Curtain of air for blowoff, cleaning, drying and cooling.

What Is The Full-Flow Air Knife?

EXAIR’s Full-Flow Air Knife is an effective way to clean, dry or cool parts, webs or conveyors. It utilises the Coanda effect to pull in large volumes of surrounding air, producing a high flow, high velocity curtain of air. The “Full-Flow” provides airflow across the entire length. A 12″ (305mm) Full-Flow Air Knife measures 12″ (305mm). It has the compressed air inlet(s) on the rear. Inlets are available on each end at a small additional charge but are not recommended when uniform airflow is required.

A series of Full-Flow Air Knives “float” layers of plastic film in the confined space of the machine.

Changing Performance by Adding Shims

The compressed air exhausts through a gap that is set with a shim positioned between the cap and the body of the Full-Flow Super Air Knife. For most applications, the .002” (0.05mm) thick shim installed in the Full-Flow Super Air Knife when it is shipped works best. There are, however, some situations that require more force and flow. Thicker shims will increase the gap opening offering higher velocity and harder hitting force. Air consumption and noise will be slightly higher.

Shim sets for Aluminium Full-Flow Air Knives include a .001″ (0.03mm), .003″ (0.08mm) and .004″ (0.10mm) thick plastic shims.

Stainless steel Full-Flow Air Knife shim sets include (1) .002″ (0.05mm) thick stainless steel shims.

EFC Electronic Flow Control
Turn off the compressed air when it isn’t needed

EXAIR’s EFC™ is a user-friendly electronic flow control for compressed air that is designed to minimise compressed air use on blowoff, 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. The timing control permits easy tuning to the application requirements while providing flexibility in sensing distance.

Filters, Regulators, Valves & More

With proper filtration of dirt, moisture and oil from the compressed air supply, EXAIR compressed air products will operate for years with no maintenance required. Use a 5 micron or smaller filter separator on the compressed air supply. To prevent problems associated with oil, use a 0.03 micron or smaller oil removal filter on the compressed air supply.  Pressure regulators permit easy selection of the operating pressure, providing infinite control of flow, force and air consumption.
