2″ Flat Super Air Nozzle Produces High Force to Clean Steel Sheet

I recently worked with a customer at a company that manufactures steel sheets. They grind, polish, and then shot blast the steel sheets. As the material exits the shot blasting chamber, some of the media still sticks to the steel and is carrying over into additional processes. To mitigate this, they installed a 1” pipe with drilled holes at the exit of the conveyor to remove the excess media and keep it contained inside of the machine. While this worked, it was using a substantial amount of compressed air which was resulting in a pressure drop across the rest of the facility when this machine was in operation.

Although their current method was doing the job for them, they couldn’t live with the increased compressed air consumption. After searching the internet, they came across the EXAIR website and were interested in learning about other blowoff methods. Typically for an application involving a wide sheet of moving material we’d look towards one of our Super Air Knives, available from stock in lengths from 3”-108”. But, in this case there was some friction between the shot blasting media and the stainless steel sheet that required brute force. They needed something that was going to give them an increased amount of force, but still reduce their overall consumption.

I recommended our HP1125 High Power 2” Flat Nozzle. With a .025” thick shim installed, the HP1125 nozzle will produce 2.2 lbs of force when operated at 80 psig. This was more than enough to remove the shot blasting media. They’re also much quieter than an open blowoff, producing a sound level of just 83 dBA. While this wasn’t a motivating factor for them, the reduction in noise was definitely welcomed. They placed some on order and replaced the 1/4″ open holes with (10) Model HP1125 2” Flat Super Air Nozzles.

For comparison, (10) 1/4″ holes will consume 690 SCFM at 80 PSIG while (10) of the HP1125 comes in at just 370 SCFM. By simply installing the HP1125 (which conveniently also has a 1/4 NPT air inlet), they reduced their compressed air consumption by a whopping 46%!! By reducing air consumption they eliminated the system pressure drop, they were also able to increase the force as the compressor was able to maintain the 80 PSIG pressure at the header pipe. This also alleviated the pressure drops experienced elsewhere in the plant.

At EXAIR we have a wide-range of different products suited to a number of different blowoff  applications. From 4mm nozzles producing just 2 ozs of force, all the way up to our largest nozzle capable of delivering 23 lbs of force and everything in between. No matter the application, EXAIR has something capable of taking care of the job. Odds are it’ll be safer, quieter, and more efficient!

EXAIR Safety Air Guns Quickly Remove Years Of Debris From Large Building’s Ceiling

The air gun is a quintessential tool found in a variety of settings. Machinists will use them to blow chips, debris, and coolant from parts as they’re being finished. They’re commonly used for final cleanup before an item is packaged…nobody wants to open up a brand new product and find dust, dirt, or dried-up coolant spots on it. They can make a quick job of cleaning off a work bench…if you intend to sweep the floor afterwards, that is. In fact, larger air guns can even be used to “sweep” the floor.

I recently had the pleasure of assisting a user who was going completely the other way…from the floor, that is. His company had been contracted by the new owners of a rather large show facility to “rehab” the building. Before they could do anything, though, he needed to clean years and years (and years, he said) of dust, sediment, cobwebs, and other various debris, from the open rafters overhead. All 42,000 square feet of overhead. And, because of their schedule for getting the facility ready for upcoming shows, it needed to be done quickly.

After discussing the application and comparing the capabilities of our various Safety Air Gun offerings to the available compressed air supply, I recommended, and they purchased, two Model 1360-48 Heavy Duty Safety Air Guns, fitted with Model 1106 High Force Super Air Nozzles. These made short work of a big part of the job, allowing them to move quickly on to the rest of the building restoration.

If you’ve got a cleanup job…big or small…perhaps an EXAIR Safety Air Gun is the solution. We’ve got them ranging from the Model 1408SS Precision Safety Air Gun, fitted with our 1108SS Atto Super Air Nozzle (2.5 SCFM; 2.0 ounces of force,) to the Model 1218-6 Super Blast Safety Air Gun, which uses our largest High Force Super Air Nozzle, the 1120 (460 SCFM, 23 pounds of force,) and 29 models in between. We can provide them with accessories such as Chip Shields, Stay Set Hoses, Rigid Pipe Extensions, and Compressed Air Hoses, as needed. Give me a call to find out which one is right for you.

Here are just 2 of our 53 distinct models of Safety Air Guns.  I bet we've got the one you're looking for.
