What is the Super Air Wipe?

EXAIR’s Super 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. Available from 3/8” (10mm) through 11” (279mm) diameters.

All models include stainless steel screws and shims. Stainless steel wire braided hose is also included on sizes up to 4″ (102mm) for added corrosion and heat resistance. Aluminium models are rated for temperatures up to 204°C (400°F) and stainless steel models for temperatures up to 427°C (800°F).

Prior to the introduction of the Super Air Wipe, the only way to blowoff, dry, clean and cool cylindrical, round, or extruded 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 Super Air Wipe provides a high volume, high velocity airflow that is uniformly ejected from the 360° of its inner diameter. The airstream attaches itself to the material running through it to effectively wipe, clean or dry surfaces. 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.

Super Air Wipe Is Easy To Use

There is a 1/4 NPT female inlet on each half of the Super Air Wipe on sizes up to 7″ (178mm). Sizes 9” (229mm) and larger include two 1/4 NPT female inlets on each half in order to maintain proper air volume and performance. Aluminium Super Air Wipes up to 4″ (102mm) include a brass tee that supplies one half directly and a stainless steel wire braided coupling hose rated at 204°C (400°F) to supply the other half. Stainless steel Super Air Wipes up to 4″ (102mm) include a stainless steel tee and a stainless steel wire braided coupling hose rated at 427°C (800°F). Larger sizes should be piped directly.

Tapped holes on the downstream side are provided for permanent mounting if the Super Air Wipe is not held in place with rigid pipe. Coupling brackets that hold each half of the Super Air Wipe together are provided which can be installed or removed quickly if required.

The aluminium Super Air Wipe is available in 11 sizes from 3/8” (10mm) to 11” (279mm) diameter. The stainless steel Super Air Wipe is available in 5 sizes from ½” (13mm) to 4” (102mm) diameter. Special diameter Super Air Wipes are available.
