EXAIR air wipes
EXAIR round air knives are designed to provide an efficient, uniform 360° airflow for blowing, drying, cleaning and cooling. Round air knives are ideal for cylindrical, round or extruded surfaces such as pipes, cables, hoses and wires. The round air knives consist of two parts that are clamped together around the material, making installation quick and easy.

How EXAIR Air Wipes work
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 centre (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 thematerial running through it (6), uniformly wiping the entire surface with the high
velocity airflow.
