What is the Standard Air Wipe?

EXAIR’s Standard Air Wipe provides a uniform 360° airstream that is ideal for blowoff, drying, cleaning and cooling of pipe, cable, extruded shapes, hose, wire and more. The split design offers easy clamping around the surface of the material moving through it, eliminating the need for threading.

The Standard Air Wipe is a good choice when the added durability of stainless steel screws, shims and hose are not required. All models include coated screws, plastic shims and a general-purpose PVC coupling air hose on sizes up to 4” (102mm). The Standard Air Wipe is best suited to applications in non-corrosive environments where temperatures do not exceed 66°C (150°F).

Prior to the introduction of the Standard Air Wipe, the only way to blowoff, dry, clean and cool these surfaces was to use a ring of air nozzles. The high air consumption and noise levels of the nozzles along with inconsistent air velocity often delivered poor results.

The Standard Air Wipe provides a high volume, high velocity airflow that is uniformly ejected from the 360° of its inner diameter. Velocity can be varied from a “blast” to a “breeze”. Air consumption and noise are low.

How The 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 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 the material running through it (6), uniformly wiping the entire surface with the high velocity airflow.

The Standard Air Wipe is available in sizes 3/8” (10mm) to 11” (279mm) in diameter. Special diameter Standard Air Wipes are available.
