Super Air Wipe at Sea

I recently worked with a Chief Engineer on a large shipping boat who was having issues with water being brought in by the mooring cables. That salt water was getting into the maintenance room where the mooring cables were wound around a large spool. He wanted to remove the water from the cable before it went below deck so the extra water could just run off the deck back into the ocean.

After talking a bit we decided on a 4″ Super Air Wipe constructed of 303 stainless steel. This way the extra water would be removed and any debris the cable pulled in with it.

The Super Air Wipes provide a full 360° conical airflow that is used to blow-off, cool, clean and dry products. A Coanda profile is designed into the body of the unit to maximize entrainment of ambient air as well as give the precision angle for the air to exit from. This gives the air stream impacting the target zone a 30° angle to the surface in order to provide a substantial shear force for debris removal. This also ensures the large volume of ambient air entrained will all travel the correct direction and not become turbulent before impinging on the surface.

To meet all the tasks at hand, the Super Air Wipes are offered in two main materials of construction. Aluminum body with brass air fittings, connected with stainless steel hardware, shim and connecting hose for up to 4” (102mm). As well as 303 stainless steel body with stainless steel bolts, shim, the connecting hose for up to 4” (102mm) and fittings. The stainless-steel components give the units better corrosion resistance, higher temperature ratings, and more durability in harsh industrial environments.

The aluminum Super Air Wipe is available in 11 sizes; the stainless steel Super Air Wipe comes in 5 sizes…all from stock.

EXAIR stocks the aluminum Super Air Wipes 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 rating up 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, we can do that as well easily.

With the creation of the Super Air Wipe, 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 Kit will solve the problem and keep production going. If you need help in selecting the proper size or want to know what material we would recommend for your application, contact us.

Product Discovery: Super Air Wipes

Easy clam-shell installation

To provide ease of installation, a unique clam-shell design was engineered to provide clamp over installation rather than traditional threading methods. This also permits quick changes in size when needed in the rapid product change environments.

Super Air Wipe Kit

The Super Air Wipe kits to help get the most out of the air wipes. A kit will include the Super Air Wipe, a filter, regulator and shim set. The filter will remove bulk liquids and debris from the compressed air to keep the performance optimal. The regulator is used to fine-tune the force provided by the Super Air Wipe. 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 airflow 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.

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.

Super Air Wipe Cools, Cleans and Dries Extruded Shapes

We have many customers that use the manufacturing process of extrusion to make their various type of products.  EXAIR has an Intelligent Compressed Air Product that works very well with these processes to provide a drying, blowoff and cooling function.

Many types of products are produced via the process of extrusion, which is to shape (as metal or plastic) by forcing through a die.  There are many advantages to the extrusion process, including it being a continuous operation, it runs at high speeds, is good for high volume and low production costs, as well as many other factors.

The extrusion process typically requires heating of the metal billet or melting of the plastic to a high enough temperature to allow it to flow and be shaped as it it forced through the die. After the product has passed through the die and has been shaped it must be cooled and this is usually achieved by passing the it through a water bath.  Once the material has been cooled, it needs to be dried to remove the moisture, before the extrusion enters the next stage of processing, like getting cut to length or printed upon.

The EXAIR Super Air Wipe is ideal for blowoff, drying, cleaning and cooling of continuous materials such as extrusions, pipe, cable and more.

The Super Air Wipe has a split design which offers easy clamping around the surface of the material, eliminating the need for threading. All Super Air Wipe models include stainless steel screws and shims.  Stainless Steel wire braided hose which is plumbed to each half, is included on sizes up to 4″ to simplify installation and plumbing. Aluminum models are rated to 400°F and the stainless steel models for temperatures up to 800°F.  Models are available in size from 1/2″ to 11″ Throat Diameters.

The Super Air Wipe provides a uniform, 360° air stream that is ideal for drying and cooling of extruded materials.

To discuss your application and how an EXAIR Super Air Wipe can benefit you extrusion process, feel free to contact EXAIR and myself or one of our Application Engineers can help you determine the best solution.
