The Harmsco WB-20 features high flow capabilities matched by thermally bonded end caps for better sealing and a rigid PVC core that resists cracking. High demand applications in residential, commercial, and industrial systems won't overwhelm the filter meaning it will last longer saving both time lost during maintenance and costs associated with replacing filters earlier than expected.

• All standard 20" filter housing
