    Filter Housings

    The Universal Approach: Tailor-Made to Your Specifications Allegheny Bradford provides filter housings for virtually every filter type, size and system. Their line of universal housings combines the best features of the finest stainless steel filer housings on the market with a full range of custom options to tailor your housing to your specifications.

    Automated Housing Cleaning Is Available With Allegheny’s Opti-Clean ABC brings you the first—and only—multi-cartridge filter housing designed for automated cleaning with CIP technology: The revolutionary Opti-Clean. Its patented design eliminates the collection chamber of traditional filter housings, and features sloped cartridge drains integrated directly into the base which allows your product to drain completely.

    When the cartridges are removed, the housing’s interior is totally unobstructed to accommodate our specially designed spraywand cleaning system. Simply insert the multi-head spraywand into the empty housing for the kind of thorough cleaning required of the most critical ultra-pure applications.
