The Super Air Knife is the latest generation of the EXAIR engineered air knives with dramatically reduced compressed air usage and noise compared to other types of blowoffs.  The Super Air Knife is truly a more efficient tool for cleaning, drying or cooling parts, webs, or conveyors.  The air flow is a uniform sheet of laminar air across the entire length with a hard-hitting force.

Replacing a noisy blowoff with a Super Air Knife results is a significant reduction in sound.  Operation at a high pressure of 80 PSIG (5.5 Bar) leads to a sound level of just 69 dBA for most applications. Air amplification ratios (entrained air to compressed air) of 40:1 is produced. It also meets OSHA maximum dead-end pressure and noise requirements, for safe operation in the vicinity of plant personnel.

Typical applications for use include-

  • Post wash part drying
  • Sheet cleaning in strip mills
  • Conveyor cleaning
  • Part or component cooling
  • Web drying or cleaning
  • Environmental separation (air curtain)
  • Pre-paint blowoff and cleaning
  • Bag opening/filling operations
  • Scrap removal on converting operations

Take advantage of the Promotional Offering by clicking on the link at the top of the page.  Qualified orders receive the free model 1210 Soft Grip Safety Air Guns as shown below.

Safety Air Guns – True Cost of Ownership

There are many inexpensive, cheaply made air guns out on the market.  If evaluated solely on purchase price, the decision of what air gun to buy seems obvious.  Only when you consider all the cost of ownership and operation, does the best direction become apparent.

A popular thumb lever operated air gun, readily available online has a base purchase price of $6.11.  The List price of the EXAIR model 1210 Soft Grip Safety Air Gun is $81.00. Wow- big difference you think, I am surely not going to spend that kind of money on a simple air gun.  Let’s take a look of the true cost of ownership for each of the guns.

Thumb Operated Air Gun
1210
EXAIR Model 1210 Soft Grip Safety Air Gun

We tested both the model 1210 and the other gun utilizing our Efficiency Lab service. We tested at 80 PSIG of supply pressure and measured and recorded air consumption, force and sound levels. Results of this testing is shown below.

Capture

From the test data, the other gun is able to provide 9% more force, but at a cost of 35% greater compressed air consumption, 5.64 SCFM more, along with an 18 dBA sound level increase (a sound level where hearing protection is needed, an additional cost to be incurred.)

If we examine the compressed air consumption, we can calculate the yearly compressed air usage, considering 4 hour per day of operation, 5 days per week, for 50 weeks out of the year.

Capture

 

A general rule of thumb for industry is that 1000 SCF of compressed air costs $0.25 to produce.Capture

As you can see, after 1 year of operation the Soft Grip Safety Air Gun has already paid for itself with compressed air savings, not to mention significantly reduced sound levels, well within the OSHA Standard 29 CFR – 1910(a) for Maximum Allowable Noise Exposure. To read more about the OSHA Standard, see this EXAIR blog. An EXAIR Safety Air Gun will continue to bring you benefits after this ROI period, and includes many other feature you do not receive with the cheap air gun.

You get the EXAIR 5 Year Built to Last Warranty which covers defects in workmanship and materials.  EXAIR’s safety air guns lead the way in standards and certification – we meet or exceed relevant OSHA standards, carry the CE mark and utilize a conflict mineral free supply chain.  We offer (5) types of Safety Air Guns, all offering ergonomic, comfortable, lightweight operation.

Safety Air Guns are also available with optional Chip Shields and Extensions (in lengths of 6″ to 6′) along with many different nozzle sizes (2.5 SCFM to 460 SCFM of air flow) and a variety of materials (Zinc Aluminum alloy, Stainless Steel, brass and PEEK plastic) to allow the configuration of the best air gun for your application.  EXAIR Safety Air Guns are great for use in applications ranging from light dust removal from delicate circuit boards to large scale, long distance, wide area blow off, cooling and drying applications and everything in between.

Be sure to check out the new VariBlast Compact Safety Air Gun for variable flow with the squeeze of the trigger!

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.

EXAIR Air Guns Increase Safety And Reduce Air Use

Many times we receive calls from customers that fall right in line with our focus here at EXAIR  – providing Intelligent Compressed Air Products that improve overall safety for operators and plant personnel in industrial operations as well as reduce compressed air usage, ultimately lowering energy costs. Such was the case last week when I received an inquiry from a customer who was looking for a handheld device that could easily attach to their existing air hose to replace the loud and inefficient homemade air nozzles they are currently using to blow off steel chips and coolant from their saws and drills. Their current set up includes a combination of smashed air guns, similar to the one shown below, some small open tubes and cheap plastic nozzles. The blowoffs were working but their operators were starting to complain about excessive noise during operation and notice the compressor in the area was running continuously during the cleaning cycle. Their first proposed solution was to lower the supply pressure which did lower the sound level and air usage somewhat, but now the exiting airflow wasn’t powerful enough to clear the debris. After doing an internet search they decided to reach out to EXAIR for assistance.

Crushed guns create high pitch wind shear and provide no relief path for the air to exit safely

All of the Safety Air Guns we offer utilize our Air Nozzles which are engineered to meet or exceed OSHA Standard CFR 29 – 1910.95(a) for allowable noise exposure levels. As the Standard reads, when employees are subjected to sounds in excess of 90 dBA, some type of engineered controls should be used to lower the sound to a permissible level. Prolonged exposure to excessive noise can result in serious health issues, like tinnitus or a constant ringing of the ears, as well as stress and reduced productivity. In addition, our engineered Air Nozzles cannot be dead ended, meeting OSHA Standard 1910.242(b). With the design of our Air Nozzles, there is always a safe path for the air to exit so the outlet pressure will not reach 30 PSIG if the nozzle exhaust were to be blocked or pressed against the skin.  Due to this design, our units are safe to operate at higher pressure, resulting in a high velocity, forceful airflow.

1210
Model 1210 – Soft Grip Safety Air Gun

For this application, I recommended the customer use our Model # 1210 Soft Grip Safety Air Gun. This particular unit incorporates our Model # 1100 Super Air Nozzle which produces a low sound level of 74 dBA, well within the OSHA guidelines, and consumes only 14 SCFM @ 80 PSIG while having the necessary power to solve their application.

What’s an EXAIR?

Sometimes taking customer’s phone calls remind me of an Abbott and Costello bit (but I have to be Costello). Conversations can feel a bit like twenty questions. Instead of opening with mineral, vegetable, or animal, customers call in wanting more information on an “EXAIR”.  For our brand manager and marketing department, it is a clear sign that what they are doing is working, but to me can be a bit confusing.

Before you start thinking I don’t know my product, please remember an “EXAIR” can be quite few things. We make the broadest variety of problem solving end-use compressed air products for industry which equates to many possibilities of what an “EXAIR” may be. Is it an Air Nozzle, an Air Knife, an Air Wipe, an Air Amplifier, an Atomizing Spray Nozzle, a Safety Air Gun, a Static Eliminator, a Vacuum Generator, a Line Vac, an Industrial Vacuum, a Vortex Tube, a Cold Gun, or a Cabinet Cooler?   Unfortunately, with no moving parts to wear out, our products sometimes will outlast their labels, so the customers don’t have anymore information. Then, I have to ask what the product does.

So I ask the customer, “does the EXAIR blow off, vacuum, clean, dry, cool, convey, evacuate, coat, divert, dust, float, open, lift, purge, or spray?”

And then I wait for the customer’s detailed and eloquent response…”It works”, they sometimes say. But most of the time they respond with all of the details or enough to determine what product they have. In, in the end, an “EXAIR” is generally a Cabinet Cooler or a Vortex Tube (though it may be any of the above selection) – and we won’t complain that our company name can be so closely associated with our products.

We have so many products because compressed air is so versatile and useful.  We have taken our expertise in compressed air and used it to solve numerous problems for our customers. This is not as easy, as it sounds.  First, you need to know how well our compressed air products can perform. Second, you need to know what kind of performance the customer needs to get the job done. For instance when working on a Cabinet Cooler sizing exercise: A customer has a control box that is 24″ tall by  36″ wide by 12″ deep.  This box is reaching temperatures that cause the electronics to fail. Generally, this temperature is going to be between 110 degrees Fahrenheit to 130 degrees Fahrenheit. The temperature in the plant was 95 degrees Fahrenheit, when it failed.  The customer would now like a Cabinet Cooler System to protect his enclosure from future temperature failures.

To calculate the heat load of the electronics, first we need to calculate the surface area in square feet. In the example above that would be 22 square feet. Second, we need to calculate the temperature differential between the outside and the inside of the cabinet.  The maximum temperature differential is 130 F – 95 F, which is 35 degree differential. With the temperature differential chart from our website, we can calculate the BTU/HR per square foot.

Temperature Conversion Table

For our example, it would be 13.8 BTU/HR/ft^2. Multiply this by our surface area. Our Cabinet Cooler needs to cool at least 303.6 BTU/HR. Our 4308 Cabinet Cooler System would be a good cabinet cooler for this enclosure. It can cool 550 BTU/Hr. It is rated for a NEMA 12 enclosure to prevent dust and oil from entering the cabinet.

To help the customer, you have to first ask the right questions. Most of these questions are listed on the Cabinet Cooler Sizing Guide on our website. What is the internal air temperature in the cabinet? What is the ambient air temperature? Are their any fans in the cabinet? What is the NEMA rating for the Cabinet? Sometimes it is best to speak with an Application Engineer to know for sure you have your bases covered.
