Festo
539989
Vacuum generator OVEM-05-H-BN-QO-CE-N-2P
The Festo 539989 is an industrial component featuring a modular design structure with a 0.45 mm Laval nozzle nominal size, a 20 mm grid dimension, and an open silencer design for any assembly position. This unit integrates an electrical ejector pulse valve, flow control valve, electrical on-off valve, filter, electrical air-saving circuit, non-return valve, open silencer, and vacuum switch, accompanied by a piezoresistive relative pressure measuring principle and a 4-place backlit LCD alphanumeric display with an indicating range of -29.5 to 0 inchHg. It provides high vacuum and standard ejector characteristics, 40 µm grade of filtration, pushing and operating button manual overrides, short circuit strength, and complete polarity protection for all electrical connections alongside an IEC 61131-2 standard switching input.
