Compressed Air Uses In Industry

From pneumatic hand tools like impact wrenches or nail guns to larger scale industrial applications like stamping presses, the use of compressed air can be found in almost any industry. In fact, it is often referred to as a “fourth utility” next to water, gas and electric.

Compressed air is used in virtually every industry!

 

Take for example in construction, workers will use a pneumatic riveter to join steel framing because of the power generated by the tool over an electrically powered device, not to mention it provides for a safer operation by removing an electrical hazard. Many companies use compressed air operated diaphragm pumps or air motor driven pumps to move expensive or viscous liquid from one location to another. These types of pumps are self priming drawing the liquid in and provide positive displacement meaning they fill and empty the liquid chamber with the same amount of liquid through a common inlet and outlet.

Amusement parks have used compressed air in some capacity in the operation of thrill rides like roller coasters or to enhance the effect of certain attractions. Compressed air can be found in hospitals where it is used for specialized breathing treatments or to power surgical instruments in an operating room. Educational facilities use compressed air for laboratory testing. You can even find compressed air in the tires on your car. Basically, when you think about it, compressed air is being used just about anywhere.

Here at EXAIR, we manufacture Intelligent Compressed Air Products to help improve the efficiency in a wide variety of industrial operations. Whether you are looking to coat a surface with an atomized mist of liquid, conserve compressed air use and energy, cool an electrical enclosure, convey parts or dry material from one location to another or clean a conveyor belt or web, chances are we have a product that will fit your specific need.

EXAIR has been providing engineered solutions since 1983.

Reduce Compressed Air Use, Maintain Effectiveness with Engineered Nozzles

I had a customer that was making steel blades. The machining operation drilled a bevel into the side every 6” (152 mm). He needed to blow off the chips from the surface. They designed a box that they indicated as a “Blow Box”. This box contained four ¼” nipples that were smashed at the end to blow onto the blade. The purpose of the blow box was to blow the chips from the surface of the blade and the machined bevel and to contain the chips. The chips would fall into a bin underneath the blow box for recycling. The design is shown below.

The chips were not completely being blown off the blade or from the inside of the bevel. He decided to contact EXAIR to see if we could help. In his design of the blow box, we discovered two issues. The open pipe was using too much compressed air causing the air pressure to drop in his system. The second problem was the orientation of the nozzles. The chips that were being blown off would settle back onto the blade as it exited. I recommended to use four of our model 1122 2” Flat Super Air Nozzles to replace the open pipe nozzles. I also suggested to have them mounted on the side of the blow box to blow across the blade.

The Flat Super Air Nozzle has a strong force that can be directed to the flat surface. With the other setup, the suspended chips could fall back onto the blade. To help remove the chips from the box, I suggested the 1 ½” Heavy Duty Line Vac model 150150. He could place the vacuum opening on the side of the blow box to capture the loose chips and transfer them into the recycle bin below. The four ¼” NPT nipples were using roughly 276 SCFM (7,815 SLPM) of compressed air. By replacing the flattened pipes with the model 1122 2” Flat Super Air Nozzle, it would save him 190 SCFM (5,380 SLPM) of compressed air. The customer was happy with a clean blade and his compressor was happy for the reduce load.

If you ever come across a situation where you need help with compressed air applications, you can always call EXAIR and speak to one of our Application Engineers.

Back At Ya!

This may not be big news as it happens almost every month.  EXAIR is continuing to grow our product line and this time it is something we have never done before.  This new EXAIR Engineered Solution doesn’t blow debris away, instead, it all comes back towards you.   Why would you want this you ask?  What does this new-fangled contraption look like?  Both of those questions will be answered below.

To answer the first question, why would you ever want debris to come back at you?  Well, this isn’t for just blowing any part or area out, this nozzle has been designed for a special purpose – to blow out pipes, tubes, extrusions, and even some blind holes or pockets.   This is ideal when working on a piping system that you may need to clean out and don’t want to push debris further into the system.   It is a quick and easy way to clean out chips from a saw cut operation for tubing or extrusion.  The nozzle could even be used to clean out cylinders or crank shaft openings on engine blocks.

So what is the name of this new nozzle and what does it look like?

What does it look like already!
What does it look like already!

 

The EXAIR Model 1006SS - Back Blow Nozzle
The EXAIR Model 1006SS – Back Blow Nozzle

This is it, the EXAIR model 1006SS Back Blow Nozzle.   The nozzle features a 1/4″ FNPT air inlet, a 3/4″ O.D. to fit into piping, extrusion, or holes, and two flats which allow for the use of a 5/8″ wrench to install the nozzle.   The nozzle is constructed of 316 Stainless Steel, utilizes  22 SCFM when operated at 80 psig, gives off 80 dBA and is designed for use with 7/8″ to 4″ I.D. pipe, tube, or holes.

The unit will also be available on our Safety Air Guns with Chip Shields to offer cleaning excellence and protection for the operators.  Like all of the stock EXAIR products, this is available with our 30 day guarantee.   So if you are not sure whether this nozzle will work on your application, give us a call, get one in, and put it through the paces.   If the Back Blow nozzle doesn’t meet your needs, simply let us know within 30 days from the date of purchase and we will take it back and provide you full credit.

If you want to discuss this nozzle or any other compressed air application, don’t hesitate to contact us.

EXAIR Super Air Wipe Provides Measurement Process Improvement

One of the most repeatable aspects of EXAIR products is the ability to make sustainable, measurable improvements to an application.  Whether the application need is for spot cooling to improve process speeds, static elimination to eliminate defects, or debris blow off to improve quality, EXAIR products fit the bill time and time again.

Air Wipe cleaning shavings from hub
Model 2403 Super Air Wipe used to clean shavings from OD of hub

In the photo above the hub is used as a quality checking device after a machining process.  The hub remains stationary while a machined part is brought into the application via robot.  During the mating of the machined part to the hub, to check proper fit and tolerance, small chips were becoming trapped between the hub measurement sensors and the machined part.

To eliminate this disturbance a 3” Super Air Wipe was installed to keep the OD of the measuring hub clean and free of debris.  Since installing the Super Air Wipe, debris and damage related measurement errors have been reduced to zero.

These tighter quality control capabilities have increased the efficiency of the application and reduced the need to rework existing product.

If you have a similar application, or one for which you think an EXAIR solution may be viable, contact an EXAIR Application Engineer.
