The Case For The EXAIR Super Air Wipe

If you’ve ever used an air gun to blow something off, you’re familiar with the cleaning ability of compressed air.  If you can get the whole object blown off from where you’re standing, there really is no substitute…but what if you need to get to the other side…or sides?

Even if your product is not on fire, you probably wouldn’t want to “limbo” under it with an air gun…

This is where the EXAIR Super Air Wipe comes in…they allow you to blow a continuous, uniform 360° air stream, all around your product.  Consider their benefits:

*Sizes: the Super Air Wipe’s compact ring design means it won’t take up a lot of room; you just need a few inches, in any direction, to install one.  We stock them in eleven sizes, from 11″, all the way down to our brand-new 3/8″ diameter.

*Durability:  All EXAIR Super Air Wipes are assembled with stainless steel shims and hardware.  Models up to 4″ come with a rugged, stainless steel wire braided hose, connecting the two halves for compressed air supply.

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

*Ease of installation:  Smaller sizes can be supported by the compressed air supply line, if a pipe is used and threaded into the connector hose’s 1/4 NPT port.  Larger sizes can likewise be adequately supported with pipe to both halves. All models have a bolt circle of 1/4″-20 tapped holes for more permanent and rigid mounting.  The split ring design is another key feature:

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

*Corrosion resistance: Depending on the environment in which the Super Air Wipe will be installed, we offer them with aluminum (3/8″ – 11″ sizes) or stainless steel (3/8″ – 4″ sizes) bodies.

*Temperature rating: Aluminum Super Air Wipes are good to 400°F (204°C) and stainless steel models are good to 800°F (427°C.)

*Range of operation: We install a 0.002″ thick shim in all stock Super Air Wipes; this is suitable for a wide range of typical industrial/commercial blow off applications…a Pressure Regulator can then be used to “dial in” the air flow precisely to meet specific needs.  If a job calls for higher force & flow, additional 0.002″ shims can be installed.  Shim Sets come with the Super Air Wipe Kits, or individual shims can be ordered separately.

*Performance: Before the Super Air Wipe, a ring of nozzles was commonly used.  In fact, they still are, but we’re trying to fix that, at every opportunity we come across.  Problem with those is, it’s hard to get an even air flow all around, which leads to inconsistent blow off.  They can also be loud & inefficient, as we’ve found in numerous Efficiency Lab tests and Case Studies, like this one…

These wasteful and loud modular plastic tube blow offs…
…were replaced with EXAIR Super Air Wipes. 24 such replacements netted the customer an annual compressed air cost savings of over $13,000.00.

…and this one…

Implementing a Super Air Wipe salvaged a $30,000 job for this customer. Click on the picture to read all about it in our Case Study Library (registration required.)

Cooling Gelatin Pills Using The Mini Cooler

I recently worked with an OEM on a cooling application for a gelatin pill forming machine they designed for their customer. In their machine design, the gelatin film leaves an extruding machine then travels between 2 punch rollers to form the pills. After the pills are formed, they are supposed to drop onto a chute feeding a conveyor to carry the pills to the bottling/packaging area.

The problem they were having was the film was retaining heat which caused the pills to occasionally stick to the roller, resulting in rejects and lost production time. They were looking for an economical way to blow cold air across the rollers and film but were concerned about putting too much demand on their customer’s compressed air system.

After reviewing the photos and discussing the details, I recommended they use our Model # 3308 Mini Cooler System with dual point hose kit. The Mini Cooler provides a 50°F temperature drop from the incoming supply air temperature and provides 550 Btu/hr. of cooling capacity. The system includes a swivel mag base for easy installation while the dual point hose kit would allow them to direct the cold air to blow across both rollers from a single device. Compressed air demand is minimal, at only 8 SCFM @ 100 PSIG, alleviating their concern for the customer’s compressed air system.

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.
