July 29, 2014 - Stainless steel industrial housings made to hold 4, 5 or 7 filter assemblies are available with Swing Bolt closure system. Entire closure system is attached to housing, which eliminates need to search for parts or bolts. Not prone to expansion and wear that might cause leaks, bolts typically do not require replacement for life of housing. Use requires operator to position hinged lid on top of housing, swing closure bolts into place, and tighten using common tools.

Critical Process Filtration, Inc. Announces a More Robust, Easier to Use Line of Filter Housings

NASHUA, N.H. -- Critical Process Filtration, Inc. of Nashua, New Hampshire, today announces a significant change in their line of industrial filter housings. In order to improve the performance of their line of cartridge filter housings, the company will now offer only the robust "Swing Bolt" closure system for stainless steel industrial housings made to hold 4, 5 or 7 filter assemblies. This is in addition to the housings that hold 12, 21, 36, 52 and 80 filter cartridges, which already employ the swing bolt system.

The company is moving away from the common "V-Band" clamp system which, though common, requires multiple tools to install, is difficult to tighten correctly, and is prone to leaks if not correctly in place. Also, higher pressure applications can cause the clamp to loosen and wear which can create leaks during filter use. Replacing the V-band clamps is also extremely expensive with costs up to 1/3 the price of a new housing.

Swing bolt closures are much easier to use than the V-band clamp and solve the leakage problem. The user only has to position a hinged lid on top of the housing, "swing" the closure bolts into place and tighten using common tools. Unlike the V-band, the entire closure system is attached to the housing, so there is no searching for parts or bolts that may have been moved after removal from the housing. Finally, the bolts are not prone to the expansion and wear that might cause leaks and they usually do not require replacement for the life of the housing.
