Polylok PL-122 Effluent Filter
The PL-122 was the original Polylok filter. It was the first filter on the market with an automatic shut-off ball installed with every filter. When the filter is removed for regular servicing, the ball will float up and prevent any solids from leaving the tank. Our patented design cannot be duplicated. Ideal for residential waste flows up to 3,000 gallons per day (GPD).

Polylok, Inc. is proud to introduce the newest addition to our effluent filter line! Ideal for flows of up to 3,000 GPD (Gallons Per Day), the PL-250 is the perfect solution for higher flows.
Polylok PL-525 Effluent Filter
The PL-525 Effluent Filter is rated for 10,000 GPD (gallons per day) making it one of the largest filters in its class. It has 525 linear feet of 1/16" filtration slots. Like the Polylok PL-122, the Polylok PL-525 has an automatic shut-off ball installed with every filter. When the filter is removed for cleaning, the ball will float up and temporarily shut off the system so solids won't leave the tank.
