Quick Condensate Removal

KNF LABOPORT® SD self-drying pumps make it possible during evacuation to blow the condensed liquid out of the pump heads at high speed, while maintaining the vacuum at a constant level.

The drying system is self-controlled and is activated by a switch on the control box. If the drying system remains switched off the pump operates in the conventional manner.
