Standard Air Wipes™ Clean Agriculture Drain Pipes

Standard Air Wipe Family

Being in Ohio, I have gone by many farmlands with rolls of black polyethylene tubes in the fields.   They use these tubes to place in the ground to create proper drainage in the fields. A manufacturer of these agricultural drain pipes sent me a video of their operation.  After the pipe was extruded, they would run it through a wash system to cool the pipe.  After the wash system, they needed to remove the water from a 4” (102mm) diameter pipe at a speed of 70 feet per minute (21 meters per minute).  They designed a home-made device that used a blower-system to blow the water off the pipe (reference photo below).  Since the pipe had ribs and the blower system is at a much lower force, the removal rate of water was only around 75%.  They needed a way to get the pipe dryer before packaging. 

This company made plastic pipe ranging from 4” (102mm) to 10” (254mm) in diameter.  When they searched for pipe and tube blow-off devices, they came across the Standard Air Wipes from EXAIR.  The design of the Standard Air Wipe blows compressed air at a 30-degree angle toward the center in a 360-degree air pattern, just like a cone.  It uses a Coanda profile to maximize the entrainment of ambient air into the compressed air stream to produce a strong force.  As a non-contact wiping device; the Standard Air Wipe is very efficient and very powerful. 

For this application, I recommended the model 2485 5” Standard Air Wipe Kit.  This kit includes our Standard Air Wipe, a Filter Separator, a Regulator, and a Shim Set.  With a ½” or 13mm clearance, it gave ample room to allow the 4” (102mm) pipe to travel through without touching and to allow for ambient air entrainment.  The Filter Separator will remove bulk liquids and debris from the compressed air to keep the unit performing optimally and to keep the pipe from getting dirty.  The Regulator is used to control the amount of force.  This helps to not over-use the amount of compressed air required for the cleaning.  With a Regulator, you can make fine adjustments to get the proper amount of air while the shims in the Shim Set will give you coarse adjustments.  With the Regulator and Shim Set together, you can “dial” in the correct amount of force required for the different speeds.  The Standard Air Wipe Kits will give you the most versatility in your system to optimize the 360-degree blow-off. 

As they removed their home-made unit and attached the Super Air Wipe, they noticed some great things.  The speed of production was increased by about 10% which matched the maximum speed of the machine.  The water removal from the surface was near 100% even in the rib area.  (Some acceptable “overlaps” in the extrusion process was cleared by QC).  They also noticed that the Standard Air Wipe was much quieter; near 82 dBA at 80 PSIG (5.5 bar).  The nearby operators were very happy with this choice as the blower-type system was very loud.  And, with no moving parts, the Air Wipe was able to remove the maintenance requirements for the blower system and used a much smaller footprint.  Also, we use a split design to mount the Standard Air Wipe around the outside of the pipe without cutting into the extruded lengths.

With the creation of the EXAIR Standard Air Wipes; uniform cleaning, cooling, and blowing around the outside of parts is a simple task.  You don’t have to worry about many nozzles to target the circumference, or a fabricated blow-off device that will waste time and money.  At EXAIR, we offer a 30-day unconditional guarantee for U.S. and Canadian customers.  This customer used the 30-day trial to try the Standard Air Wipe.  After the testing, they will now purchase the model 2491 11” Standard Air Wipe Kit for their largest pipe.  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 size for your application, you can contact an Application Engineer at EXAIR for help.

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.

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.

Super Air Wipe Provides Long-Lasting Solution for Extrusion Blowoff Application

 

The Super Air Wipe has no moving parts to wear out requiring little to no maintenance when supplied with clean, dry compressed air. I recently spoke with a maintenance manager who worked for a company that had been using the same unit for over 7 years. In this application, the Super Air Wipe was used to remove a light coating of oil from the exterior of extruded shapes. Despite showing some obvious signs of wear and tear (and perhaps a little bit of residual oil from the environment), it was still serving the needs of the application as-is.

It may be dirty, but it is still working to remove a light coating of oil from an extrusion!

The Super Air Wipe is available in aluminum construction in sizes ranging from 3/8” – 11” in diameters. All Super Air Wipes comes with stainless steel hardware and stainless steel shims. Sizes up to 4” include a brass tee that supplies one half of the Super Air Wipe while a stainless steel wire braided hose supplies the other side. Sizes over 4” should be piped directly to each ¼ NPT compressed air inlet. In addition to aluminum construction, the Super Air Wipe is also available in 303 stainless steel for corrosive or high temperature applications. The Stainless Steel Super Air Wipe can withstand temperatures up to 800°F and is available in sizes from ½”-4” from stock.

Much like the Super Air Knife, the Super Air Wipe has ¼-20 tapped holes along the downstream side that can be used for mounting. Smaller Super Air Wipes can be supported by rigid compressed air pipe that is used to supply the air into the product. The Super Air Wipe is also infinitely adjustable through the use of shim sets or a pressure regulator. Kits will include the Super Air Wipe, shim set to make gross adjustments to the airflow, an auto-drain filter to keep the air clean and dry, and a pressure regulator. By adjusting the input supply pressure to the Super Air Wipe, you regulate both the force and flow that is projected onto the target material. Increasing the input supply pressure will increase both the force and flow from the Super Air Wipe.

If you’re processing any type of hose, wire, or extruded shapes that could benefit from installing a Super Air Wipe give us a call. With all sizes shipping from stock on an order received by 2:00 pm ET we can have one to you as early as tomorrow!
