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.
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.
If you have any questions or need further assistance, please contact an application engineer.
