Festo
539984
Vacuum generator OVEM-07-H-BN-QO-OE-N-2P
The Festo 539984 is a modular industrial component featuring a 0.7 mm nominal size Laval nozzle, a 20 mm grid dimension, an open silencer design, and an any assembly position. This unit incorporates high vacuum or standard ejector characteristics, a 40 µm grade of filtration, manual override via pushing and operating buttons, and integrated functions including 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. Equipped with short circuit protection, piezoresistive relative pressure measurement, polarity protection for all electrical connections, an IEC 61131-2 standard switching input, and a 4-place alphanumeric backlit LCD displaying -29.5 to 0 inchHg, it offers normally closed or open contact switching element functions and window or threshold value comparator switching functions with an open valve function.
