EXAIR’s smaller Swivel Fittings for the Atto, Pico, and Nano Super Air Nozzles

Are you tired of having to scrounge around the production floor for the right fittings to precisely position your air nozzle? Not only is it a pain to try and find the correct fittings, extensions, etc. but once you do the position of the nozzle is hard to adjust. To alleviate this problem, EXAIR has designed a variety of different sized swivel fittings that allow you to precisely position the nozzle, then easily tighten and lock into place.

Don’t waste time using various pipe fittings to position your nozzle, use an EXAIR Swivel Fitting

EXAIR’s Swivel Fittings are available in 9 different sizes, from as small as 1/8” NPT male x M4 x .5mm female and up to 1” NPT male x 1” NPT female. The smaller swivels (M4-M6) are constructed of 316 stainless steel and the swivels ranging from 1/8 NPT – 1” NPT are available in 303 stainless steel. The Swivel Fittings allow for movement of 25 degrees from the center axis for a total movement of 50 degrees. This permits correct placement of the blowing angle, helping to optimize the performance of your blowoff process. With no gaskets or seals to wear out, there’s no maintenance required to maintain optimum performance.

Swivel Fittings

Swivels can be used on any of our Air Nozzles up to 1” and can also be used with the Adjustable and Super Air Amplifiers. By simply adding a “W” suffix to the part number, the correctly sized swivel fitting will be added to your order. For example, an 1122W would be one of our 2” Flat Super Air Nozzles with a ¼ NPT male x ¼ NPT female Swivel Fitting included. Stop wasting time trying to find the proper fittings and positioning for your blowoff nozzles!

Improving Auger Cleaning Process Using 2″ Flat Super Air Nozzles And Swivels

I recently worked with a customer who was looking to improve the cleaning process on the  inside of one of their screw augers. They were currently using a couple of 1/4″ pipes as air wands to clean the left over powder on the auger blades and direct it toward a chute at the bottom which fed into another auger used for recovery. While the setup worked somewhat, they were concerned with the amount of air they were using as well as the OSHA safety concerns associated to using open ended pipes and excessive noise levels.

The customer was able to send a sketch of their current setup and after some further conversations, I recommended our Model # 1122 2″ Flat Super Air Nozzle and our Model # 9053 1/4″ NPT Swivel Fitting. The 2″ Flat Super Air Nozzle produces a 2″ wide, high velocity laminar airflow and uses only 21.8 SCFM (80 PSIG) while maintaining a low sound level of only 77 dBA. The Swivel Fitting allows for 50 degrees of movement, so they can achieve the best angle to direct the air to the critical areas.

2″ Flat Super Air Nozzle
Swivel Fittings available from M4 up to 1″ NPT

All of our Air Nozzles are engineered to meet or exceed OSHA Standard 1910.24(b) for 30 PSIG dead end pressure, they cannot be dead-ended, there is always a path for the air to safely exit so the outlet pressure will never reach 30 PSIG. In addition, our products are going to meet the OSHA Standard CFR 29 – 1910.95(a) for allowable noise exposure levels as well.

If you are looking to reduce air consumption and noise while improving operator safety, give us a call at 800-903-9247 for assistance.

Engineered Air Nozzles and Jets Outperform – Save Air, Increase Safety, Save Money

EXAIR’s Engineered Air Nozzles and Air Jets provide a simple solution to lower compressed air usage and reduce noise levels for compressed air blowoff operations.

Why Air Nozzles and Jets – When compared to commonly used open copper tubes or pipes, compressed air savings can be as high as 80%. And with less compressed air, sound levels are greatly reduced.  A 10 dBA noise level reduction is typical.  All EXAIR Air Nozzles and Jets meet the Occupational Safety and Health Administration (OSHA) maximum dead end pressure and sound level exposure requirements. They also carry the CE mark.

The largest selection of engineered Air Nozzle sizes and materials are only available form EXAIR 

EXAIR Nozzles are engineered to take advantage of the Coanda effect to amplify the airflow up to 25 times or more. Compressed air is ejected through the small orifices and surrounding air is entrained into the main stream. The resulting air stream is a high volume, high velocity blast of air at minimal consumption.  EXAIR manufactures many styles, from the very small, but powerful Atto Super Air Nozzles, to the largest 1-1/4 NPT Super Air Nozzle.  Also offered are 1″ and 2″ wide Flat Super Air Nozzles, and the Back Blow style for cleaning out tubes, pipes, channels or holes from 1/4″ to 16″ in diameter.
EXAIR Air Jets utilize the Coanda effect (wall attachment of a high velocity fluid) to produce air motion in their surroundings.  A small amount of compressed air (1) is throttled through an internal ring nozzle above sonic velocity.  A vacuum is produced, pulling in large volumes of surrounding, or ‘free’ air, through an around the jet (2).  The exit flow is the combination of the two air sources (3).

How an Air Jet Works

EXAIR manufactures Air Jets in two types, High Velocity, and Adjustable with materials of construction of brass and Type 303 Stainless Steel.  The High Velocity Air Jet uses a changeable shim to set the gap, controlling the force and flow of the air.  The Adjustable does not use a shim, and has a micrometer gap indicator and locking ring to allow for varying force and flow performance.

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.

Swivels, StaySets,MagBases2

 

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.

Bench Testing with Blowoff Kits

Last week, a customer connected with us online via the chat option.  He explained that he was working on a project to remove dust from parts on a table conveyor, situated in a 3 x 5 array. He had purchased the EXAIR Blowoff Kits model 1909SS and model 1910 and had been able to bench test and develop a blowoff system that was successful.  He was ready to scale the up design and procure a set of nozzles and swivels that would work in the automated process.

“(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.

“Set it and forget about it” is a benefit you can realize from many EXAIR Intelligent Compressed Air Products. If you’d like to find out more, give me a call.
