The NP Discfilters, the 19 & 22-series are based on the same modular design as our successful NP Drumfilter series, plus new developments to adapt the disc filter technology for aquaculture criteria. These developments sets the NP Discfilter to the most optimized disc filter solution on the aquaculture market.

The filter has a number of filter media discs attached to a drum. The filter is provided with filter cassettes of a well-proven design that also simplifies maintenance and the possibility to change filter openings, if required. The filter is rotated by a helical-worm gear motor via a lubricant-free chain, driving on the peripheral of the center drum. This feature reduces stress on the drum structure and drive arrangement, leading to lower power consumption and reduced maintenance costs.
