Pentek OAC Series Filter

Pentek / Ametek / Culligan OAC Series Water Filters

Also branded as: Pentek / Ametek / Culligan / Kleen Plus / Plymouth Products / Pentair / American Plumber / Bruner / US Filter CBC Series

The OAC-20BB, made from modified cellulose-based filter media, is processed into sheets and assembled into cartridges for use in standard 20-inch Big Blue filter housings.




Certain applications may require pre-filtration.

Change-Out Frequency

Change-out frequency will depend on the oil burden they have to handle. Because no appreciable increase in pressure drop is observed during service life, the filter must be changed when its adsorption capacity is exhausted.
