Standard Air Wipe Shim Set

On a Standard Air Wipe, compressed air exhausts through a gap which is set with a shim positioned between the cap and the body. The Standard Air Wipe is shipped with a .002 Inch (0.05mm) thick plastic shim installed which works best for most applications. Force and flow may be easily increased by adding shims to open the gap. Shim Sets include (2) each of a .001 Inch (0.03mm), a .003 Inch (0.08mm), and a .004 Inch (0.10mm) thick shim. Shim sets are included with all kits or may be purchased separately.

How the Standard Air Wipe Works

How the Standard Air Wipe Works

Compressed air flows through an inlet (1) of the Air Wipe into an annular chamber (2). It is then throttled through a small ring nozzle (3) at high velocity. This primary airstream adheres to the Coanda profile (4), which directs it down the angled surface of the Air Wipe. A low pressure area is created at the center (5) inducing a high volume flow of surrounding air into the primary airstream. As the airflow leaves the Air Wipe, it creates a conical 360° ring of air that attaches itself to the surface of the material running through it (6), uniformly wiping the entire surface with the high velocity airflow.
