These Pfeiffer oil return units puts the oil mist droplets from the ONF 4-20 oil mist elminator back into the rotary vane pump via the gas ballast as a liquid. These products are recommended for Pfeiffer vacuum pump applications that often require cycling of the vacuum chamber to atmosphere.

For Pfeiffer Pumps up to 12 m3/h (7 CFM). The Pfeiffer ONF 16 (KF16) oil mist filter separator is mounted on the exhaust connection of Pfeiffer rotary vane pumps. It prevents air pollution from operating oil mist that is ejected by the pump to a greater or lesser degree depending on the operating pressure. The filter inserts are installed in a housing made of corrosion-resistant aluminum and consist of a cylindrical filter of glass polyester fleece. The filter inserts are opened by an incorporated pressure relief valve when the contamination becomes excessive so that the maximum working pressure of 1.5 bar (absolute) cannot be exceeded. The collected oil mist, now fluid can be observed through the sightglass and discharged with the drain screw.

For Pfeiffer Pumps up to 20 m3/h (12 CFM).The oil mist filter is fitted to the exhaust port of the rotary vane vacuum pump. It reduces air pollution by operating fluid mist expelled in greater or smaller quantities (depending on the working pressure) from the pump. The filter is not suitable where the pumping of corrosive gases and vapours or those gases which tend to polymerise or which can cause resinification of the oil mist filter is involved.
