EXAIR Safety Air Gun Accessories Improve Effectiveness and Safety

Safety Air Gun with accessories

EXAIR offers 5 different styles of Safety Air Guns; Precision, VariBlast, Soft Grip, Heavy Duty and Super Blast.   You can read more about the different styles of Safety Air Guns from a previous EXAIR blog “Not All Compressed Air Guns Are The Same” written by Justin Nichol. I will be targeting the accessories that can enhance the features of the EXAIR Safety Air Guns. These additions will make the Safety Air Guns more dynamic without sacrificing safety, efficiency, or durability.

Precision Safety Air Gun with Chip Shield
eg. 1408SS-CS

Chip Shields:

OSHA 1910.242(b) requires chip guarding when compressed air is used for cleaning. EXAIR offers Chip Shields with our Safety Air Guns to meet this requirement. They are made from a polycarbonate disc which is practically unbreakable and protects the operator from any blow back of metal shavings or coolant. They come with a durable rubber grommet that squeezes onto the extensions and can be adjusted to maximize protection. We offer Chip Shields for the Precision, VariBlast, Soft Grip, and Heavy Duty Safety Air Guns with or without aluminum extensions.

Heavy Duty Safety Air Gun with extension.
eg. 1350-72

Extension Pipes:

For those far away targets and hard-to-reach areas, EXAIR offers aluminum extension pipes to attach to the Safety Air Guns. They can range from 6” (15 cm) to 72” (183 cm) in length. This light-weight and durable material allows for easy handling to reach high above your head or to span across unsafe areas. With the EXAIR air nozzles at the end, the blowing force is not sacrificed as the back pressure will generate a high velocity air stream. The aluminum extensions are offered with the Variblast, Soft Grip, and Heavy Duty Safety Air Guns. The Super Blast Safety Air Guns has the option for two different lengths of extensions, 3 feet (91cm) and 6 feet (183 cm).

Soft Grip Safety Air Gun with Stay Set Hose.
eg. 1210-6SSH

Stay Set Hose:

In certain situations, you may need a way to blow air around a corner or in a tight space. The Stay Set Hose gives you that possibility of manually adjusting or re-adjusting the nozzles to target the correct areas. The hose has a “memory” function, and it will not creep or droop until you physically move it again. They come in lengths from 6” (15cm) to 36” (91cm), and they are offered with the Soft Grip and the Heavy Duty Safety Air Guns.

Coiled Hose

Coiled Hoses:

To get the proper amount of compressed air from the piping system to the Safety Air Guns, EXAIR offers a series of Coiled Hoses. They are made of a durable abrasion-resistant nylon material that is 12 feet long (3.6 meters). They have swivel fittings to allow for easy uncoiling, and a spring strain relief to keep the hose from kinking at the ends. The coiled design makes it easy to reach around the work area and retract back to the substation. This will help to keep the hose off the ground where potential dangers could occur. We offer 3 different connection sizes of 1/8” NPT, ¼” NPT, and 3/8” NPT. They can be used with our Precision, VariBlast, Soft Grip, and Heavy Duty Safety Air Guns. With the proper size, the Coiled Hoses can connect easily to the Safety Air Guns and supply the required amount of air with a minimal amount of pressure drop.

Regulator and Filter

Filter Separators/Regulators:

To improve the use of the Safety Air Guns, EXAIR offers a series of filters and regulators. The filters will remove dirty particles and liquid water from the compressed air that can affect the performance of the Safety Air Gun as well as contaminate the surface that you are cleaning. The regulators can control the amount of air pressure used for the Safety Air Gun; making them even more efficient. The idea for compressed air savings is to use the least amount of compressed air to do the job. If you only need 40 PSIG (2.8 Bar) to blow off an area, then you can save almost 40% of your compressed air as compared to doing that same job at 80 PSIG (5.5 Bar). The combination of a filter and regulator will allow you to control the proper amount of clean dry air to be used.

 

All of our Safety Air Guns are fitted with our engineered Air Nozzles  which make them OSHA compliant for noise and dead-end pressure. With the accessories, you can optimize the use of the Safety Air Guns to better fit your application. If you need help in determine the correct Safety Air Guns and accessory items, you can contact an Application Engineer for help. If you are within the U.S. or Canada, you can take advantage of our 30-day unconditional guarantee to trial any of our stocked Safety Air Guns.

Not All Compressed Air Guns Are The Same

If you work in an industrial plant or manufacturing environment, chances are you use some type of compressed air gun for cleaning parts, work areas, etc. Many air guns purchased through large industrial suppliers are a common choice due to the cost of the gun but as the saying goes – “you get what you pay for”. These types of guns may be cheap to purchase but they are also made cheap and have parts that can break easily, like the trigger or nozzle. In many cases, the nozzles on these guns are also in violation of OSHA requirements, producing dangerous discharge pressures and loud noise levels, which can lead to costly fines or potentially deadly injuries.

EXAIR offers 5 different styles of Safety Air Guns that not only eliminate these concerns, but also provide a more efficient operation, which can reduce energy costs. All of our Safety Air Guns are fitted with our engineered Air Nozzles  which meet OSHA Standard 1910.242(b) for 30 PSI dead end pressure, as they provide a relief or safe path for the air to exit if the nozzle were to be blocked or pressed against an operator’s body so the exiting air pressure will never reach 30 PSIG. They are also engineered to entrain surrounding air across the profile of the nozzle, which produces a smoother airflow, ultimately reducing wind shear, resulting in much lower sound levels, meeting OSHA Standard 29 CFR 1910.95(a).

 

 

The Precision Safety Air Gun body is made of a durable high impact, glass reinforced nylon, providing for a lightweight, ergonomic operation. These guns feature a curved extension, ideal for delivering a powerful stream of air in hard to reach areas, like clearing debris from drilled holes. All of the nozzles used with these units are either 316ss construction for durable, corrosion resistance or PEEK plastic for non-marring applications. The air inlet is 1/4 FNPT and there is a convenient hanger available for safe storage.

 

 

 

Our NEW VariBlast Compact Safety Air Guns are ideal for light to medium duty processes, featuring a variable flow trigger to achieve different force levels ranging from 2.0 ounces up to 1 pound, depending on the nozzle. The body is cast aluminum and there are (2) 1/4 FNPT air inlets available, 1 on the bottom and 1 on the back of the gun, as well as a storage hanger, for easy installation. Nozzles are available in zinc aluminum alloy, 303ss, 316ss and PEEK plastic. These guns are available with aluminum extensions from 6″ up to 72″.

 

 

The Soft Grip Safety Air Guns are commonly used in long-term use applications as they feature a comfortable grip and long trigger which helps to reduce hand and finger fatigue. The cast aluminum construction is well suited for more rugged environments and again, features a hanger hook. These guns can be fitted with aluminum, stainless steel or PEEK plastic to meet the demands of a variety of applications and are available with 6″ – 72″ aluminum extensions for extra reach or Flexible Stay Set Hoses , allowing the user to aim the airflow to a specific target area. The air inlets for these guns are going to be 1/4 FNPT.

 

 

 

EXAIR’s Heavy Duty Safety Air Guns deliver higher force and flows than other air guns, as these units feature a 3/8 FNPT air inlet, which maximizes the compressed air flow to the engineered Super Air Nozzle. Like the Soft Grip, the durable cast aluminum body is designed for use in tough industrial processes, and the ergonomic and comfortable trigger are ideal for hours of use. Aluminum extension are available, again in lengths from 6″ up to 72″, but feature a larger diameter for optimal flow and superior durability.

 

The Precision, VariBlast, Soft Grip and Heavy Duty Safety Air Guns are ALL available with an optional, polycarbonate Chip Shield to protect personnel from flying chips and debris, further meeting OSHA Standard 1910.242(b) for the safe use of compressed air.

 

Lastly we offer our Super Blast Safety Air Guns. The Super Blast Safety Air Guns are ideal for wide area blowoff, cooling or drying a part, as well as long distances. They feature a comfortable foam grip and spring loaded valve that will shut off the airflow if the gun is dropped. These units use our larger Super Air Nozzles and Super Air Nozzle Clusters, providing forces levels from 3.2 lbs. up to 23 lbs. Depending on which nozzle is fitted on the assembly, air inlets will range from 3/8 FNPT up to 1-1/4 FNPT. Aluminum extensions are available in 36″ or 72″ lengths.

EXAIR Accessories – We’ve Got you Covered

When you work with us here at EXAIR, we strive to have all the ancillary items that you might need to make your installation a success, without having to find components at the last minute or perhaps using the wrong sized components. Each specific product line such as Super Air Knives or Line Vac air operated conveyors have specific accessories such as mounting brackets or plumbing kits which EXAIR has made to simplify the installation of those particular products. We also carry generalized accessories which work across all of the product lines so you do not have to use multiple vendors or purchase orders.

Silencing Mufflers – Per OSHA Standard 1910.95(a), a worker must not be exposed to sounds levels above 90 dBA for any eight hour shift of a 40 hour work week.  EXAIR offers several types of mufflers including – Reclassifying, Sintered Bronze, Straight-Through and Heavy Duty.  For reducing the noise associated with an EXAIR E-Vac Generator, Vortex Tube, Cabinet Cooler System, or the exhaust air from cylinders, valves and other air powered equipment, we’ve got a muffler that will help to keep the noise level at an acceptable level.

Mufflers

Solenoid and Manual Valves – The easiest way to reduce compressed air usage and save on operating expense is to turn off the compressed air to a device when it isn’t needed. EXAIR carries a wide assortment of solenoid valves, with offerings in the NEMA 4/4X classification, and supply voltages of 24VDC, 120VAC, and 240VAC.  We also have manual ball valves from 1/4 NPT to 1-1/4 NPT and a foot operated valve, with 1/4 NPT connections.

Valves

Swivel Fittings, Stay Set Hoses and Magnetic Bases – To provide a great degree of flexibility for positioning an EXAIR Super Air Nozzle, Air Jets or Air Amplifiers, EXAIR offers several items.  The Swivel Fittings have 25 degree of movement from the center axis, providing a total of 50 degree of adjustability.  The position is locked in place and holds until adjustment is needed. For applications where frequent re-positioning of the air device is required, the Stay Set Hoses are ideal.  Simply mount the hose close to the application, bend it to the shape preferred, and because the hose has “memory”, it will not creep or bend.  Lastly, the Magnetic Bases are another option for flexible, movable installations.  The base has a on/off valve, and a powerful magnet to hold in any vertical or horizontal mounting arrangement.

Hoses – EXAIR can provide hoses for your application.  For the Line Vac air operated conveyor applications, we offer conveyance hose – a durable, clear reinforced PVC hose, in diameters of 3/8″ to 3″ ID, and lengths up to 50′. On the compressed air side, we can provide 12′ Coiled Hoses with 1/8, 1/4, and 3/8 NPT connections, and also 3/8″ and 1/2″ ID hose in lengths to 50′.

Hoses

Filter Separators, Oil Removal Filters and Pressure Regulators – Perhaps the most important accessories for use on a compressed air device are filters and regulators. Filtering the compressed air of dirt, debris, moisture and oil will help to prevent build up inside the EXAIR products, leading to longer service life, and less time spent cleaning, while providing optimum performance. Regulating the air pressure allows for tuning of the performance, using the proper amount of compressed air to obtain satisfactory results.

Filter and Regualtors

“(Stay) Set It And Forget It”

The Stay Set Hose is a popular, and practical, accessory for use with many of our blow-off products. Thread one end onto a compressed air supply connection, thread a Super Air Nozzle (or maybe even a small Air Amplifier or short Air Knife) onto the other end, and you’ve got an easily repositionable blow off…which will reliably hold its position.

That last part was of considerable importance to a caller I had the pleasure of assisting recently. Some of the CNC machines in their shop were fitted with flexible plastic tubing (commonly used for coolant & cutting fluid,) supplied with compressed air to blow off chips & debris from the tooling as the parts were being machined. They use our Super Air Knives in other blow off processes (where they used to use costly & loud open blow off devices,) and wanted to see if engineered products might reduce their compressed air consumption & noise levels in the machine shop too. (spoiler alert: Yes, they can.)

Thing is, they really needed the flexibility of the modular hose, but it’s not rated for the pressure supply required for a Super Air Nozzle. This is what makes our engineered products so efficient; they use the Coanda effect to amplify the compressed airflow..and they use the supply pressure to do that. So they can’t install a Super Air Nozzle on what they have now.

Enter the Stay Set Hoses: They’ll bend to direct the nozzles’ air flow right where you need it, and they’ll keep it there until you bend it again. Which (back to what’s most important to this caller) is exactly what they needed. With our efficient & quiet Super Air Nozzles, they’re saving compressed air and improving the conditions of their work environment. With the Stay Set Hoses, they’re able to quickly & easily rig the air flow before running a job, knowing they won’t have to worry about it until the job’s done.

EXAIR Stay Set Hoses hold their position as long as you need them to. All day, every day.

High Power Super Air Nozzles Provide Forceful Air Flow

When considering the application of a compressed air product, we have an awful lot of discussions with callers about the amount of force generated.  Now, if that’s all you want, you’re not going to get more force from compressed air flow from anything but an open ended blow off.  There are problems inherent with this: it’s unsafe, it’s loud, and it’s a horribly inefficient way to use compressed air.  By the time they’ve called EXAIR, they probably know this, but the main concern is still the same: solving their application.

Good news is, you don’t need a lot of FORCE for most blow off situations.  Think about it…how much do sawdust, machining chips, coolant droplets, etc., weigh, anyway?  All you really need to do is optimize the air flow, which is EXACTLY what EXAIR Intelligent Compressed Air Products are engineered & designed for.  So, we talk a LOT about how often a high amount of force isn’t needed in compressed air blowing applications.

Then…I got a call from a user who needed force.  They had an air knife installed to blow parts out of a mold, as the halves separated.  There’s a rectangular array of parts in a multi-cavity mold, and the air knife just wasn’t getting them all out, all the time.

The air knife, was, of course, originally chosen for its efficiency, but it just wasn’t delivering the needed “punch.” They even tried other shim thicknesses (which increases the outlet air gap) to increase the flow & force delivered, and that helped a little, but wasn’t 100% effective.

The solution came in the form of an array of HP1125-9212 2″ High Power Flat Super Air Nozzles, supplied with 12″ Stay Set Hoses.  They’re able to mount these closer to the mold than the air knife, and the ability for each nozzle to operate independently meant they were able to be aimed precisely where they can do the most good.  They are now able to evacuate the molds the first time, every time.

Sometimes, you DO need the high force of the HP1125 2″ High Power Flat Super Air Nozzle

If you have questions about how to get the most out of your compressed air use, give me a call.

This Is A Hold Up

To clarify, right off the bat:

  1. Nobody is getting robbed here.
  2. Nothing is being delayed, especially a shipment from EXAIR. If it’s in the catalog, it ships on time, 99.97% of the time, for 17 years & running. This has nothing to do with this blog; I just never get tired of bragging about that.

Today I wanted to write about installing EXAIR products, but hey, it’s Friday, so I thought I’d start with something that would get your attention. If you’re still reading, I guess it worked.

We talk to users…and potential users…all the time about how to install an Air Knife, Air Nozzle, Vortex Tube, etc. And the answer is…it depends. But, it’s almost always quick and easy.

Consider the EXAIR Super Air Knife. There are a few ways to hold one in place:
*There are 1/4″-20 tapped holes, every 2″ along the bottom. These can be used to bolt it to just about anything you want to bolt it to.
*The 1/4″-20 cap screws can also be replaced with fasteners of sufficient length to allow use of a bracket. In fact, this is what we use for…
*The Universal Air Knife Mounting System – it’s a quick and convenient way to support an Air Knife. It’s especially beneficial to precisely position the Super Air Knife for optimum performance.
*Last but not least, Super Air Knives 24″ and longer need to be plumbed to both ends for proper performance. If you hard pipe it in, it’ll be as well supported as the piping.

EXAIR Super Air Knives are easy to install, no matter what the length, or application.

Then there’s our Super Air Nozzles:
*With standard, common NPT threads, these are easy to install anywhere you have an existing air line. You can get NPT adapters for darn near any threaded connection, off the shelf, from a friendly local air compressor or hydraulic/pneumatics shop.
*We’ve got Stay Set Hoses in lengths from 6″ to 36″ – these let you reposition the Air Nozzle at will. It’ll “stay set” until you bend it again.
*Our Swivel Fittings can be used with any of our Super Air Nozzles, as well as our Air Amplifiers, for sturdy, yet easily repositionable, installation.

EXAIR Swivel Fittings or Stay Set Hoses - no better way to optimize your air flow than aiming it where it needs to be!

Flexible Stay Set Hoses

Adjustability and flexibility have been common themes for some of my recent blog posts. The EXAIR Flexible Stay Set Hoses certainly exhibit those same characteristics and more. For applications where frequent re-positioning of the air product, whether it be a Super Air Nozzle or Jet, or small Super Air Knife, the Flexible Stay Set Hoses are ideal.  Simply mount the hose near the area of application, and bend and shape it to deliver the air flow precisely as needed.

stay-set-hoses

Flexible Stay Set Hoses

The hose was designed and manufactured to have “memory”, and it will not creep or bend. It will maintain the positioning and directional aim of the air flow until it is reshaped to a new position.  The materials of construction allow it to withstand temperatures up to 158°F (70°F.)

The Flexible Stay Set Hoses are offered in 5 different lengths – 6″, 12″, 18″, 24″, 30″, and 36″ and with 2 different end configurations – 1/4 male NPT x 1/8 female NPT and 1/4 male NPT on both ends, providing many options to match the needs of the application.

The Magnetic Base works in conjunction with the Stay Set Hoses, as they also allow a flexible location for positioning the hose.
