Air Amplifiers – Air Pressure or Air Flow Volume

When talking about Air Amplifiers there are two (2) kinds when considering what best fits your needs. An amplifier that is used to increase pressure above your compressor’s ability are also known as air boosters. These boosters are sometimes needed for specific processes which demand much higher pressures. Amplifiers that increases the volume flow rate of your compressed air or nitrogen are the type of amplifier that EXAIR manufactures. 

EXAIR’s Super Air Amplifiers will increase the volume of air on to a target or being circulated in an environment. EXAIR’s Air Amplifiers use the Coanda effect pulling in large volumes of surrounding air to produce high volume, high velocity outlet flows up to 25 times their consumption rate.

Air Amplifiers have no moving parts and are basically maintenance free. EXAIR’s amplifiers operate on a source of clean compressed air and do not use electricity. The outlet flows are easily adjusted by opening or closing the air gap. By regulating the supply pressure you can tune in your outlet flow to meet your specific needs. Vacuum and discharge ends of the Air Amplifier can be ducted, making them ideal for drawing fresh air from another area or for moving smoke and fumes away.

Super Air Amplifier Family

EXAIR has 5 standard sized Air Amplifiers ranging from 3/4″ (19mm) to 8″ (203mm) plus an Adjustable Air Amplifier . If you have a specific application EXAIR can manufacture Air Amplifiers to fit your application. If you have a project and think EXAIR’s Air Amplifier or any of our Intelligent Compressed Air Products please contact me or any of our qualified Application Engineers to discuss your project.

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.

Compressed Air Receiver Tanks On The “Demand” Side

Most any air compressor is going to have a receiver tank…from the “pancake” types that might hold a gallon or so, to the large, multi-tank arrangements that facilitate both cooling and drying of compressed air in major industrial installations.  The primary purpose of these receiver tanks is to maintain proper operation of the compressor itself…they store a pressurized volume of air so that the compressor doesn’t have to run all the time.  Receiver Tanks, however, can also be used to eliminate fluctuations at points of use, especially in facilities where there might be a lot of real estate between the compressor and the compressed air consuming products.
