KNF N 1200 Series
Robust Design

With a flow rate of up to 130 ± 10% l/min, an ultimate vacuum of up to 150 mbar abs., and a pressure of up to 6 bar g, KNF N 1200 vacuum pumps and compressors are designed to withstand challenging conditions, providing an impressively high level of gas tightness of up to 6 x 10-6 mbar l/s.

Two-Fold Safety

Double diaphragm models are also available for applications requiring ultra safety. The second membrane in the pump design effectively prevents gas from leaking into the environment in the event of a fracture.
