Extend & Lok™ (3", 4" & 6")

We look at problems as opportunities. We heard from many of our customers that they love our filters but they were having difficulty installing them into existing tanks. Why? Because the inlet or outlet pipes weren't long enough to accept the filter tee or baffle. Our Extend & Lok™ is a simple, easy to use solution that can extend the inlet or outlet pipe and make filter and/or baffle installation a snap. They are now available to fit 3", 4" & 6" pipe.

Goes Well With

PL-68 Effluent Filter

The PL-68 is much more than just an effluent filter. The housing can also be used as an inlet baffle (tee) or, with any 4” outlet septic tank filter. The housing is designed to accept Polylok’s snap in gas deflector to deflect gas bubbles away from the tee and to keep the solids in the tank. The PL-68 is ideal for residential waste flows up to 800 GPD.

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).

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 A1800 ™ Series

Like the PL-68, this filter was designed for residential applications. The cartridge design allows for easy installation and maintenance and comes with our standard baffle (tee). All A1800 Series filters feature a locking tab that securely locks the filter into the tee. With 1/16” filtration, this filter is available in 18” and 22” lengths. The 22” A1800 comes with a built in gas deflector.

Zabel A100, A300, A600™-8 Series

A smaller version of the original Zabel® Disc Dam Filter, the A100/ 300/ 600 - 8 Series is becoming a popular choice for applications where increased effluent quality is desired.

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.
