Low-cost housings for Keystone filters
A patent-pending line of 222 Giant® Industrial Filter Housings and Cartridges has been introduced by the Keystone Filter Division of Met-Pro Corporation. The product offers submicronic filtration in a low-cost high-surface-area configuration, with a special double 222 o‑ring seal to ensure integrity and safety.
The housings are designed to fit Keystone's unique line of 222 pleated polypropylene filter cartridges that are available in 0.2, 0.45, 1.0 and 5.0 nominal micron ratings. A new Key-Cyst Filter, which also uses the Giant 222 housing and cartridges, is being registered with NSF for cyst protection, and is being used by beverage bottling companies to protect their water from Giardia and Cryptosporidium cysts.
