The Kraken filter flyer

The Kraken® Filter provides higher treatment flow rates in a smaller footprint. Each 7.5 inch diameter filter cartridge has 170 sq. ft. of media surface area. The Kraken® Filter’s low loading rate successfully overcomes high maintenance requirements and frequent clogging issues often found in other filter systems advertising high loading rates.

NJDEP Verification On-line Approval
The New Jersey Corporation for Advanced Technology (NJCAT) original Verification Report of February 2016 for the Kraken limited its use to off-line installation only. In its April 4, 2016, correspondence to the NJDEP, NJCAT submitted an addendum to that February 2016 Report, indicating the NJDEP Filter Protocol dated January 2013 for on-line installations were met or exceeded. No other requirements within the NJDEP’s March 16, 2016, certification have changed.
