360° Air Wipe Comparison for Extrusion, Hose, Cable, Pipe and Wire Blowoff or Cooling

When it comes to blowing off extrusions, cables, pipe, tubing, hose, or wire, the EXAIR Super Air Wipe is an ideal product that often stands alone in this field. From time to time I will receive a call asking about a block style blowoff for wire or cabling, maybe even small extrusion, and the Super Air Wipe is always there to provide a true 360° blowoff compared to what the customer is used to.

See, the block style blowoffs are similar to the SAW in they both offer a clamshell design that will open and close into place around the product to prevent the user from having to “thread the needle”.  Also, they both operate off compressed air. The means by which they deliver the air is where the stark contrast in performance begins.

First, let us take a look at how these block style blowoffs deliver the air to the product being blown off. Generally, inside of these, there are a couple holes on each half of the block that are drilled at an angle to deliver the air onto the surface of the product. These block style products have to be kept fairly close in diameter to the product so that the air contacts the surfaces and they are for the most part offered in smaller sizes only.

Now, how does the Super Air Wipe deliver the air to the product being blown off?  The air enters (1) into an internal chamber that fills (2) and then dispurses through a continuous gap (3) on each half of the wipe that is set by a shim. The shim can be interchanged with different thicknesses to give a course adjustment to the volumetric flow of air. The air then follows the Coanda profile (4) of the Super Air Wipe to maximize entrained air (5) and exits at a 60° included angle (6) to impact the surface of the part at a full 360°.

Stock Super Air Wipe Product OfferingBlock Style air wipes also have a tendency to operate very loudly, often exceeding 90 dBA and more. This will affects personnel directly and can also affect their communication when attending to a processing line.  Super Air Wipes operate at 82 dBA with 5″ and smaller diameters. Up to 89 dBA for diameterss from 6″-11″.

The Super Air Wipe is available in eleven sizes from stock in aluminum (up to 11″ dia.) while the stainless steel configurations are available in five sizes from stock (up to 4″ dia.).  If aluminum or stainless steel don’t fit the requirements of an application, custom sizes and materials are always available with short lead times.

Tight-fitting locations are ideal for a Super Air Wipe install.

If you notice that the block style air blowoff is leaving streaks or maybe the physical space requirements of the block are too much to fit into your production line, please contact an Application Engineer and let us help you determine which Super Air Wipe is going to be right for your needs.

Static Elimination for Hose, Pipe, Extrusion, Cable and Wire

EXAIR’s  Gen4 Super Ion Air Wipe provides a uniform 360 degree ionized air stream that clamps around a continuously moving part to eliminate static electricity and contaminants. It is ideal for removing dust, particulates and personnel shocks on pipe, cable, extruded shapes, hose, wire and more. This engineered product has undergone independent laboratory tests to certify it meets the rigorous safety, health and environmental standards of the USA, European Union and Canada that are required to attain the CE and UL marks. It is also RoHS compliant. New design features include a metal armored high voltage cable to protect against abrasion and cuts, a replaceable emitter point, integrated ground connection and electromagnetic shielding.

The Gen4 Super Ion Air Wipe uses a small amount of compressed air to entrain high volumes of ambient air. Two shockless ionizing points powered by our Gen4 UL Component Recognized 5kV Power Supply fills the air stream with static eliminating ions. That airflow impacts the surface of the material running through the air wipe and neutralizes the charge.

The Gen4 Super Ion Air Wipe, which compliments EXAIR’s complete line of Gen4 Static Eliminators, has an aluminum construction that is lightweight and easy to mount using the tapped holes provided. Two sizes include a 2 inch (51mm) diameter and a 4 inch (102mm). There are no moving parts to wear out. Visit EXAIR.com to see the entire Gen4 Static Eliminator product line and 1/2 inch through 11 inch Super Air Wipes for applications without static.

Purchase a Gen4 Super Ion Air Wipe through our online promotional before March 31st, 2019 and receive a fee AC Sensor.

Atomizing Nozzles – No Drip Deflected Flat Fan and 360° Hollow Circular

EXAIR manufactures three types of Atomizing Nozzles – Internal Mix, External Mix, and Siphon Fed.  Within the Internal Mix family, there are two specialty nozzles, the Deflected Flat Fan and the 360° Hollow Circular patterns.

Internal Mix nozzles are for pressure fed applications not requiring independent air and liquid control.

The model AD2010SS is the No Drip version of the Deflected Flat Fan and is shown below. Our patented No Drip design prevents unwanted post spray drips from wasting expensive fluids or ruining product finishes. The benefit to this design is that no secondary compressed air line is necessary to activate the on/off valve for the liquid, which is the case for competitive nozzles.

Model AD2010SS – No Drip Internal Mix Deflected Flat Atomizing Nozzle

The Deflected Flat Fan patterned nozzle is designed for applications where space is a limited.  The spray pattern is at a right angle to the orientation of the nozzle, allowing the spray to be placed precisely where it is needed in tight quarters.  They are ideal for coating the insides of enclosures and ductwork.

The model AT2010SS is the No Drip version of the 360° Hollow Circular and is shown below.

AT2010SS – No Drip Internal Mix 360° Hollow Circular Atomizing Nozzle

The 360° Hollow Circular patterned nozzle is designed for applications where the spray pattern is to be orientated away form the nozzle in all directions.  They are ideal where a smooth and even coating is needed on the internal surface of a pipe or duct.  They are also good for processed where a mist is needed over a large area, including dust suppression, humidification, and cooling.

NoDripIM360HC-Pattern

The No Drip feature is a patented† design that has the added benefit of positively stopping the liquid flow when the compressed air is shut off. Post spray liquid flow can cause quality issues from unwanted drips on painted or coated surfaces.  Also, the No Drip feature helps to conserve and save on liquid use, reducing costs of expensive coatings or chemicals.

When the compressed air supply is shut off, the No Drip nozzle positively seals off the flow of liquid, eliminating over spray and drips. The design allows for just one compressed air line, there is no need for an additional to control the No Drip mechanism.

If you have questions about Atomizing Spray Nozzles, or would like to talk about any of the EXAIR Intelligent Compressed Air® Products, feel free to contact EXAIR and myself or any of our Application Engineers can help you determine the best solution.

The Deep Hole Vac-u-Gun = Dual Problem Solver

A little while back, I was contacted by a customer who was looking for a way to clean chips and debris out of tapped holes in an engine block. They were familiar with our products, having used them in several different areas in their plant, and had done some early research into our Air Nozzles.

They were considering using our small M4 Back Blow Air Nozzle in the process. The Back Blow Air Nozzles produce a 360° airflow that blows away from the end of the nozzle and in many cases, are the ideal solution for treating the inside diameter of hose, pipe, machined holes, etc. These unique nozzles, eliminate the concern of forcing particulate further down into a machined hole or the safety issue of blowing material out of the opposite end of an open tube or pipe.

EXAIR Back Blow Air Nozzles come in three sizes, for bores from 1/4″ to 16″ in diameter!

In this particular case, having the material blown out of the hole increased the risk of possible cross contamination somewhere else in the engine block so they were also thinking of incorporating some type of recovery system like our Chip Vac or one of our Line Vacs but were concerned with having to use two separate devices.

Once again, EXAIR has the perfect solution, the Deep Hole Vac-u-Gun. The Deep Hole Vac-u-Gun features a small blow tube (1/8″ OD) that provides a small blast of air to dislodge or loosen foreign material while simultaneously providing vacuum to carry the debris away.

If you have a similar application or would like to discuss how an EXAIR Intelligent Compressed Air Product can help solve a unique situation, contact an application engineer for assistance.
