PURitech Gmbh products

This system, developed by PURItech, combines an active regeneration (external fuel injection) and a passive regeneration (catalyzed filter or fuel born additive). The filter regeneration is automatically controlled during operation. DAS-DBS Type A and B are designed for application with low load.

The filter self-cleaning is achieved by a catalytic coated filter surface. The DPF2 system is equipped with an additional pre-filter. That’s why even at low temperatures a self-cleaning regeneration is secured. The DPF1/DPF2 system is designed for construction machines, tractors and stationary engines.

This affordable system utilizes permanent and passive filter regeneration with fuel born additive. The installation works as a replacement for all common machines.
