89922.tifNozzle-Based Cleaning System
Booth 2603 – This company  offers a complete line of baghouses and cartridges collectors with special design features that include a nozzle-based cleaning system that induces more cleaning air into the media. By improving the amount of cleaning air induced, the filter will last longer, and allow more process air to pass through or recover better. A recent nozzle improvement induces even more cleaning air into the filter than before. In addition, certain nozzle types also allow the reverse pulse-jet system to operate at lower compressed air psi levels. In this proven technology the venturi at the top of the bag/cage is eliminated. This allows for a lower design and  operating system pressure drop. Scientific Dust Collectors, Alsip, IL 708-597-7090  www.scientificdustcollectors.com
