The powerful KNF N940 series diaphragm vacuum pumps are especially well suited for all applications requiring excellent suction speed with low absolute pressures. The KNF N940.5 APE-W pumps including a diaphragm stabilization system which allows for high suction, especially in the low-vacuum range. The KNF N940.5APE-W pumps are available with optional adjustable flow rate; in this case, either an potentiometer or an external controller with an analog signal input will alter the motor speed. These pump versions make it possible to adapt the flow rate to the requirements of a specific applications process.

These KNF Neuberger N940.5 APE-W diaphragm vacuum pumps are excellent for transferring and evacuation of air and gas applications. They are dry oil-free operating diaphragm pumps so they will not add contamination to the vacuum media. The improved KNF stabilization system and efficient brushless motor allows these pumps to run quiet and cool. These KNF Neuberger N940.5 APE-W diaphragm vacuum pumps automatically adapt to any input power supplied between the range of 90 to 264 VAC.

The KNF Neuberger N940 series of diaphragm vacuum pumps offer a high level of performance in a compact unit size. Typical applications are in the fields of analysis, chemistry, medicine, production technologies, and also support turbomolecular systems as roughing pumps.
