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.

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.

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.

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!
