Permanent Washable Filter Elements
Permanent Washable Filter Elements

Permanent Washable Filter Elements

These filters with permanent, washable elements clean even the dirtiest water supplies. The novel filter elements are constructed of thin plastic discs with precisely-sized grooves, stacked on a central core. To select the correct size Keller filter assembly, specify the filter assembly with a port size equal to the size of the line on which it will be installed. The flow rate in the line will likely be less than the rated flow of the filter at two psi pressure drop, and therefore the initial pressure drop will likely be less than 2 psi. Fit the permanent elements in your existing standard filter housings without modification, or order a complete filter assembly permanent element. Great for plant laboratory water supplies, cooling water systems, boiler feedwater systems, water spray nozzles, and more.
