Super Air Wipe Overview

What do you do when you need to cool, blowoff, or dry extruded objects? How will you support the products to do these tasks, and how will you get your extrusions through them? Consider using engineered compressed air products air for these applications to provide instant on/off capability, fine tuning adjustment of the air flow, low noise levels and OSHA safety. The EXAIR Super Air Wipe is designed to work well with continuous production products like extrusions, wire and cable.

The Super Air Wipe is a highly efficient compressed air powered device that provides a uniform 360° air stream that is ideal for blowoff, drying, cleaning and/or cooling of pipe, cable, extruded shapes, hose, wire and more.

The clam shell design of EXAIR’s Super Air Wipe offers easy clamping around the surface of the material moving through it that eliminates the need for time-consuming and cumbersome threading.  All models utilize stainless steel screws and shims and for sizes up to 4″ (102mm) a Stainless Steel wire braided connecting hose is included.  Aluminum models are rated for temperatures up to 400°F (204°C) and stainless steel models for temperatures up to 800°F (427°C).

Mounting the EXAIR Super Air Wipe is very easy, it can be accomplished by using either the 1/4 – 20 tapped holes on the downstream side or by utilizing a hard pipe compressed air supply line.  Connecting the EXAIR Super Air Wipe to your compressed air supply is straightforward, there are (2) 1/4 FNPT compressed air inlets on throat sizes up to  7″ (178mm) diameter (one on each half), while the 9″ (229mm) & 11″ (279mm) diameters have a total of (4) 1/4 FNPT compressed air inlets (two per half) to ensure proper air volume for maximum performance.

Prior to the introduction of the Super Air Wipe, one way to blow off, dry, or clean extruded objects 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, which is similar to the construction of EXAIR Super Air Knife provides a high volume, high velocity airflow that is uniformly ejected from the entire 360° of its inner diameter. The airstream adheres to the surface of the material running through it (Coanda Effect) to effectively wipe, clean or dry surfaces.

To further explain how the EXAIR Super Air Wipes work, reference the animation below: Compressed air flows through the inlet (1) of the Air Wipe into the 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 down the angled surface of the Air Wipe.  A low pressure is created at the center (5) inducing a high volume flow of surrounding air into the primary airstream.  As the airflow exits the slot, it creates a conical 360° ring of air that will attach to the surface of the material running through it (6) uniformly wiping the entire surface with the high velocity airflow.

How The Super Air Wipe Works

The EXAIR Super Air Wipe is 1.13″ (29mm) thick on all (11) Aluminum models that range in size from 3/8″ (10mm) to 11″ (279mm) throat diameter and all (5) Stainless Steel models that range in size from 1/2″ (50mm) to 4″ (102mm).   The performance can be altered by changing the inlet air pressure or by adding an additional shim, which will nearly double the force!
