EXAIR Super Air Wipes: Conical Blow-off for Cable, Pipe, Hose, Extrusions

EXAIR manufactures two types of Air Wipes; the Standard Air Wipe™ and the Super Air Wipe™.  They are designed to blow an airstream in a concentric pattern around the outside of pipes, cables, extruded shapes, hoses and much more.  In this blog, I will focus on the features and benefits of the Super Air Wipes.  Their unique design, variety of sizes, and construction definitely makes this product “Super”.

The Super Air Wipes are used to blow-off, cool, clean and dry products.  The air is blown in a conical 360o pattern completely around the outside of parts.  EXAIR engineered a Coanda profile to entrain large amounts of ambient air.  This will increase efficiency by using less compressed air and still generate a large force to perform the task.  The Coanda profile is set at a 30o angle to increase the contact area and keep debris away from the portion of the product that has already been cleaned.

Simply open the two halves, and clamp them around your product…no threading!

The construction of the Super Air Wipes is also unique.  It has a split design to allow for an opening to place around the part; so, you will not have to break or rethread the material.  They also use stainless-steel screws and stainless-steel shims.  For diameters up to 4” (102mm), they will come with a braided stainless-steel hose to supply compressed air to both halves.  The stainless-steel components give the units better corrosion resistance, higher temperature ratings, and more durability.

EXAIR manufactures the Super Air Wipes with two different body materials, aluminum and 303 stainless steel.  EXAIR stocks the aluminum models with inner diameters from 3/8” (10 mm) for wire and cables up to 11” (279mm) for large pipes and hoses.  The aluminum models have a temperature range good to 400oF (204oC).  We also stock the stainless-steel models from ½” (13mm) to 4” (102mm) inner diameters, and they have a temperature range up to 800oF (427oC).  If you require different diameters or materials, don’t be afraid to ask.  EXAIR also makes specials.

Super Air Wipe Kit

We also offer options with the Super Air Wipes.  We have kits to help get the most out of the Air Wipes.  A kit will include the Super Air Wipe, a filter, a regulator and a shim set.  The filter will remove bulk liquids and debris from the compressed air to keep the performance optimal.  The Regulator is used to control the force.  This helps to not over-use the amount of compressed air required for the job.  With a regulator, you can make fine adjustments to get the proper amount of air.  For coarse adjustments, you can add shims to increase the air flow and force.  They are easy to install on the Super Air Wipes to allow for applications to have more cooling, faster drying, and better removal for tough debris.  For cleanliness and control, the Super Air Wipe Kits would be recommended for your application.

Here are some additional advantages in using the EXAIR Super Air Wipes that I did not cover.  They are OSHA safe in dead-end pressure and noise exposure.  So, they are quiet.  We placed pre-tapped holes on each half of the bodies for easy mounting with brackets or attachments.  They do not have any moving parts or require any electricity to operate.  The non-contact wiping actions that the Super Air Wipe can provide helps to support cleaning items without affecting the surface finish.  Also, you won’t have to worry about replacing cloths or brushes that will slow production and wear over time.

With the creation of the EXAIR Super Air Wipes, uniform cleaning, cooling, and blowing around the outside of parts is a simple task.  You don’t have to worry about a variety of nozzles to target the circumference, or a fabricated blow-off device that will waste air and take much time out of your day.  A simple purchase of the Super Air Wipe is all you need.  You can order them from our website at www.EXAIR.com or call us at 800-903-9247.  If you need help in selecting the proper product for your application, you can contact an Application Engineer at EXAIR for help.

EXAIR Super Air Wipe Helps Welding Process

Several years prior we had a customer that was using a block-type Air Wipe from a competitor to remove water from an extrusion.  These air wipes were built using materials similar to UHMW and the 2 halves were hinged with air holes drilled into it.  They were using these block air wipes on several lines and decided to try an EXAIR Super Air Wipe after contacting our Application Engineers. The interesting point was that it required 5 block type air wipes to equal the efficiency of 1 EXAIR Super Air Wipe.

Since one EXAIR Super Air Wipe equaled the performance of 5 of the competitor’s products it consumed less air, was less expensive and produced less noise.  Also in space sensitive applications the EXAIR Super Air Wipe is much thinner than the block type.  To highlight this the Super Air Wipe is 1.13″ thick on all 11 models that range from 3/8″ to 11″ throat diameter.

Another clear advantage is performance. The block air wipe performance can only be changed by altering the inlet air pressure while the EXAIR Super Air Wipe can also be changed by adjusting the inlet air pressure or changing the air gap of the Air Wipe. Simply by changing out an internal shim, the air gap will allow more or less volume of compressed air at a given pressure. By changing shims and adjusting pressure, EXAIR Super Air Wipes provide the flexibility which leads to a successful application across industry.

EXAIR’s Super Air Wipes are engineered to use compressed air efficiently and maximize force upon the target.

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.

If you are interested in discussing EXAIR’s Super Air Wipes, I would enjoy hearing from you.
