EXAIR’s Super Air Nozzles Qualify for Energy Rebate Incentive

The patented design of EXAIR’s 1” and 2” Flat Super Air Nozzles makes them a highly efficient option when seeking a powerful, flat airflow. A precise air gap across the width of the nozzle provides a forceful stream of high velocity, laminar airflow without consuming high amounts of compressed air and also resulting in a greatly reduced sound level compared to some of the alternative flat nozzles available in the market.

Did you know that upgrading to an efficient engineered air nozzle, such as the 1” or 2” Flat Super Air Nozzle, can make you eligible for an incentive from your energy provider? Similar to other energy-saving programs for upgrading to LED light bulbs or high-efficiency HVAC systems, these are made available to you as an incentive to start using more energy efficient products.

The energy costs associated with the generation of compressed air, often referred to in industry as a 4th utility, can make it expensive. These programs are offered to encourage you to use engineered products that are more energy efficient due to the reduction in compressed air consumption. Essentially, they’re offering you free money to implement a solution that will also save you money. It almost sounds too good to be true!! But these products, after implementation and receiving the incentive, will continue to save you money year after year.

The US Department of Energy, in conjunction with the NC Clean Energy Technology Center, provides a website that allows you to search the various programs available to you in your state. The DSIRE® website allows you to select your state, then select your energy provider to determine what programs are offered.

In Southwest Ohio, Duke Energy provides an incentive that offers $40 USD each per engineered air nozzle that is installed. When replacing open pipe or tube, these nozzles generally pay for themselves relatively quickly. But, when combined with a $40 USD rebate, that return on investment happens even quicker!!!

Don’t leave free money on the table. If you’re using open pipe or tube, or inefficient plastic flat nozzles, replace them with an engineered air nozzle from EXAIR. If you need help determining what rebate programs are available to you in your area, we’re also here to help. Contact an EXAIR Application Engineer today!

Big Nozzle, Big Award…Again!

The year was 2016, and it was quite a time for sports fans:

  • Team USA dominated at the Summer Olympics in Rio de Janeiro. Swimmer Michael Phelps won five Gold Medals, and gymnast Simone Biles won a Gold Medal on her own, and another for the team event, contributing to the 46 total Gold Medals won by United States Olympians.
  • The Chicago Cubs and Cleveland Indians took the World Series to all seven games…and extra innings in Game Seven. That makes it hard to disparage either team, but the Cubs prevailed, winning the Fall Classic for the first time in 108 years.
  • World Series heartbreak notwithstanding, Cleveland sports fans were pretty happy a few months earlier when the Cavaliers cinched the NBA Championship in seven games, defeating the heavily favored Golden State Warriors…who beat the Cavs in both of their regular season games that year.

Another big winner (non-sports) that year was EXAIR Corporation’s Model EF5010SS External Mix Narrow Angle Flat Fan Pattern 1/2 NPT Atomizing Spray Nozzle…it won Plant Engineering’s Product of the Year Bronze Medal Award in the Fluid Handling category. Yes, there’s a Compressed Air category, and our products have won a TON of those too…as well as some other categories:

  • Material Handling (Line Vacs)
  • Maintenance Products (Super Air Nozzles)
  • Environmental Health (High Lift Reversible Drum Vac)
  • Automation & Controls (EFC Electronic Flow Control)
Just a few of our past Product of the Year award winners in categories other than “Compressed Air”.

Anyway, now it’s 2021, and the No-Drip version of that Atomizing Spray Nozzle – Model EF6010SS – has won Plant Engineering’s GOLD Medal Award in the Fluid Handling category. Model EF6010SS offers the same performance as the EF5010SS:

  • Liquid flow rates from 141 to 303 gallons per hour (tested with water)
  • Flat fan spray dimensions from 15″ wide (6″ from target) to 25″ wide (15″ from target)
  • Atomized spray at a distance of up to 35 feet away

And, of course, the No-Drip feature means you can instantly stop liquid flow by shutting off the compressed air supply, up to 180 cycles a minute, if needed. This is a great feature to have to cut down on the cost – and the MESS – associated with overspraying.

Our comprehensive line of Atomizing Spray Nozzles has options for most any liquid that can be sprayed, with a wide range of flow rates and pattern size/shapes. The 1/2 NPT External Mix Narrow Angle Flat Fan model is ideally suited for liquids with higher viscosities where a higher flow rate/thicker coating is needed, as opposed to a humidification or misting application, where a smaller Atomizing Spray Nozzle might be specified. Some current, successfully reported, applications include:

  • Snack food provider – applying flavoring to bulk snack materials.
  • Commercial bakery – spraying cooking oil onto pans used in a conveyor oven.
  • Sporting goods manufacturer – applying adhesive to the tops of skateboard decks to glue the grip tape on.

If you’d like to discuss a particular liquid spraying application, I’d love to help…give me a call.

Air Guns to Meet & Exceed OSHA Standards

The Soft Grip Safety Air Gun is a blow gun which is in stock for immediate shipping and has a durable cast aluminum body that is suited for rugged industrial use.  The ergonomic design has a large trigger and a soft, comfortable grip for easy operation and keeps the hand in a comfortable position for extended periods of use. A convenient hook hanger allows for easy storage when not in use.  Aluminum Extensions (up to 72″ long) and Stay Set Hoses (up to 36″ long ) can be fitted, providing access to hard-to-reach places. Chip Shields are available for most models, protecting operators from flying debris, helping to meet an important part of OSHA’s requirements for the safe use of compressed air, OSHA Standard 1910.242(b).

blog_SGSAG_500x

The Soft Grip Safety Air Gun can be configured with dozens of nozzle options, air consumption as low as 2.5 SCFM @ 80 PSIG of supply pressure and up to 60 SCFM if needed.  Nozzle materials include Zinc Aluminum alloy, Stainless Steel, and PEEK thermoplastic as well as forward blowing or back blow nozzle options.

Using any of EXAIR’s Safety Air Guns with an Engineered Air Nozzle will provide safe and efficient use of compressed air, reduce energy costs, and eliminate harmful dead-end pressures (again, helping to comply with the OSHA standard for safe use of compressed air) when compared to standard commercial air blow guns, open pipes, and other homemade attempts to use compressed air efficiently and effectively.

When outfitted with EXAIR’s engineered air nozzles, the Soft Grip Safety Air Gun is a powerful ally to reduce personnel noise exposure and protect them from noise-induced hearing loss. This is another important safety feature complying with OSHA’s standard 29 CFR-1910.95(a). Lowering the ambient noise level also helps to improve operator satisfaction of their working environment.

The Soft Grip Safety Air Gun can be configured to meet applications from delicate blowoff of electronic circuit boards to large chip removal in metal cutting operations, and everything in between.

If you have questions regarding the Soft Grip Safety Air Gun or would like to talk about any EXAIR Intelligent Compressed Air® Product, feel free to contact an Application Engineer who can help you determine the best solution.

6 Important Factors when Choosing a Safety Air Gun

If you look at operating costs alone, compressed air can be just about the most inefficient method there is for cleaning parts. If you just look at the risks, it’s potentially very dangerous too. Don’t even get me started on the insufferable noise it can make.

For cleaning parts, most folks are familiar with the use of an air gun. You can find the simplest of these in many industrial settings: a valve (often in the form of a handheld trigger device) fitted with a nozzle of some sort (often in the form of an open ended tube, pipe, or fitting to focus or direct the air flow). These have all three of the “downsides” I opened this blog with. Of course, these concerns can be mitigated to a high degree by using the right tool for the job. That’s where engineered products like EXAIR Safety Air Guns come in. Let’s look at how we can address these three “downsides”:

Efficiency: This is all about compressed air consumption. In the simplest of air guns mentioned above, consumption is only limited by the passages in the valve (or trigger) and the discharge fitting…and those limits are usually negligible. Modifying the ends (see examples below) to focus the air flow usually has minimal effect, because you’re not appreciably changing the total cross sectional area of the discharge opening:

Here are a few modified thumb trigger air guns that were sent in for Efficiency Lab testing. Left to right, compressed air consumption at 80psig supply pressure was 34.2 SCFM, 30.9 SCFM, and 28.2 SCFM. For comparison (more on this later,) EXAIR Model 1210 Soft Grip Safety Air Gun uses only 14 SCFM and generates a very similar flow pattern.

Safety: Remember learning about kinetic and potential energy in grade school? Well, when you compress air to 100psig, fitting all that air into a much smaller space creates a TREMENDOUS amount of potential energy:

The block on the left represents a cubic foot of air at atmospheric pressure. The one on the right represents how much space the first one takes up when compressed to 100psig. The energy imparted by this process HAS to be handled with care.

One problem with the thumb guns above is, if you were to jam into the palm of your hand and pull the trigger, a large component of that potential energy (pressure) turns into kinetic energy (force)…more than enough to break the skin and cause a potentially fatal condition known as an air embolism. In the United States, OSHA (Occupational Safety and Health Administration) regulates compressed air devices used for cleaning purposes. All EXAIR Safety Air Guns comply with Standard 1910.242(b) by providing a relief path to ensure that it cannot be dead ended, and thus never create over 30psi measurable at the outlet)

EXAIR Super Air Nozzles cannot be dead ended, ensuring the outlet pressure won’t reach OSHA limits, regardless of supply pressure.

Noise: Another problem is, another component is turned into sound pressure…discharging air from a direct opening is quite loud. OSHA standards address these with limitations on outlet pressure and sound level. All EXAIR Safety Air Guns comply with Standard 1910.242(b), which limits the outlet pressure (by providing a relief path to ensure that it cannot be dead ended, and thus never create over 30psi measurable at the outlet) and all but our largest Super Blast Safety Air Guns comply with Standard 1910.95(a) limits for continuous 8 hour sound level exposure.

Which brings us to the topic of this blog: How exactly did THEY (our customer who used to use the thumb guns above) select the right Safety Air Gun, and how can we apply that to getting the right Safety Air Gun for YOU?

These steps aren’t all-inclusive, and they don’t necessarily need to be followed in order, but if you call an EXAIR Application Engineer about selecting a Safety Air Gun, here’s what we’re gonna talk about:

Ergonomics: We offer five distinctive styles of Safety Air Guns:

From small part cleaning by hand, to wide area blowoff, and all points in between, EXAIR has a Safety Air Gun for most any application.

Our thumb gun user (as I alluded to above) chose the Model 1210 Soft Grip Safety Air Guns (top right). They had a number of typical industrial applications where the operators had the parts or surfaces to be blown off right in front of them. They liked the integral storage hook and rubberized hand grip, but the VariBlast Compact (top middle) or Heavy Duty Safety Air Guns (bottom left) were also considered. The VariBlast Precision (top left) and Super Blast Safety Air Guns (bottom right) were too focused or more powerful, respectively, than needed.

Airflow pattern: Honestly, I could make a good case for this being the first consideration. Selection of any blowoff product – be it an Air Nozzle, Air Amplifier, Air Knife, Air Wipe, etc., will largely depend on the size and shape of the airflow.

variety of airflow patterns…and effective distances…are available from EXAIR’s comprehensive line of Super Air Nozzle products.

Application specific concerns: Everything we’ve discussed so far has involved aiming the blow off stream away from the operator, in the direction the device is aimed. In addition to wide variety of engineered Air Nozzles, EXAIR offers a number of options for these products:

Atto Back Blow Nozzles can blow out recesses or holes as small as 1/4″ in diameter.
Scrape off, and blow away, stubborn debris with the Model 1244-48 Soft Grip Super Air Scraper.

If you’re looking for a portable, hand-held compressed air blow off product that’s quiet, safe, and efficient, look no further than EXAIR Corporation’s extensive line of Safety Air Guns. If you’d like to find out more, give me a call.
