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.
