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.

PL-625 Effluent Filter

The PL-625 filter is ideal for grease trap applications. The 1/32” filtration has been shown to reduce fats, oils, and grease (FOG) by as much as 60% to 98%! The filter may be used in onsite wastewater systems that require a finer level of TSS removal. Whatever the application, Polylok has the filter for you!

Zabel A100, A300, A600™-12 Series

The original Zabel® Disc Dam Filter was patented in 1959. The 12” series filters have been filtering wastewater longer than any other filter in the wastewater industry. In 2000 Zabel made the best even better by introducing a complete redesign of the original with more great features and finer levels of filtration. In 2006, Polylok, Inc. purchased the Zabel filter line and with the benefit of our in house engineering department, we are continuing to improve the product line.
