KNF N 880.3 AN.22E, with Dynamic Mass Balancing
Dynamic Mass Balancing

For applications that demand exceptionally smooth-running throughout the whole working range of the pump, KNF has developed a dynamic mass balancing for the N 880.3 series. It automatically damps out the out-of-balance resulting from gas forces.

Possible areas of use for the N 880.3 series include roughing pump for turbomolecular pumps, energy technology especially SF6 gas handling, and many more.
