Festo
539985
Vacuum generator OVEM-10-H-BN-QO-OE-N-2P
The Festo 539985 is a modular industrial component featuring a 0.95 mm Laval nozzle, a 20 mm grid dimension, and an open silencer design enabling assembly in any 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 a vacuum switch with high vacuum and standard ejector characteristics. Equipped with piezoresistive relative pressure measurement, a backlit 4-place alphanumeric LCD display with a -29.5 to 0 inchHg indicating range, and short-circuit strength with polarity protection across all electrical connections, it provides IEC 61131-2 standard switching inputs.
