Super Blast Safety Air Gun Saves Air vs. an Inefficient Homemade Lance

Published on by exaircorpLeave a comment

I was recently contacted by a Chicken Farm in Canada about a blow off application for cleaning the dust and debris off the walls and ceilings in their barns. They currently use a 185 SCFM portable, engine driven compressor and a lance made from 3/4″ open copper tube. The barns are rather large, approximately 10′ high by 500′ long, and they place the compressor in the middle of the barn and have a 250′ length of hose going to the homemade blowoff. This setup worked fine for a minute or so but then the airflow would start to weaken at the point-of-use and the compressor would run continuously as it wasn’t able to maintain pressure to keep up with the demand of the copper pipe.

After discussing the details of the application, I recommend the customer use our Model # 1214-6 Super Blast Safety Air Gun with 6′ aluminum extension. This would reduce the air demand to 91 SCFM, more suitable for use with the existing 185 SCFM compressor.

 

Super Blast Safety Air Gun Model # 1214

The design of the Super Blast Safety Air Gun features a spring loaded manual valve, providing automatic shutoff and a comfortable foam grip. The 6′ extension provides the extra reach they need to effectively treat the walls and ceilings in the barn.

The Super Blast Safety Air Guns are ideal for wide coverage, long distance applications. They use our Large 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 range from 3/8 FNPT up to 1-1/4 FNPT and aluminum extensions are available in 36″ or 72″ lengths.

Super Ion Air Knife Removes Debris In Vinyl Window And Door Manufacturing

Published on by exaircorpLeave a comment

I recently worked with a vinyl window and door manufacturer on a static issue they were experiencing during the manufacturing process. After the aluminum frames are cut to length they are placed into a holding fixture where the vinyl seals are placed in a channel inside the frame and clamped together. A machining tool then travels around the parts to trim and machine the excess material, creating dust and some small chips. They tried to vacuum the debris away but were still seeing some residual material cling to the surface due to static, which resulted in manual rework of the parts, slowing down the production cycle.

The customer was able to send a drawing of the holding fixture for reference and after reviewing the information, I recommended they use our 18″ Super Ion Air Knife Kit in this application. The Super Ion Air Knife provides a high velocity, laminar sheet of ionized air across the length of the knife. As the positive and negative ions neutralize the surface charge, the airflow is able to clean the part of the unwanted material so it can be more easily vacuumed away. Using the regulator included in the kit, they can reduce the supply pressure to control the outlet flow and velocity to an acceptable level that doesn’t disrupt the current process.

Super Ion Air Knives are available in standard lengths from 3″ up to 108″ and ship from stock.

If you have an application you would like to discuss or are considering an EXAIR product for your process, please contact an application engineer for assistance.

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

Published on by Russ BowmanLeave a comment

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.
