Festo
539993
Vacuum generator OVEM-07-H-BN-QO-CN-N-2P
The Festo 539993 is a modular industrial component featuring a 0.7 mm nominal size Laval nozzle, a 20 mm grid dimension, and an open silencer design with any assembly position. This unit integrates an electrical on-off valve, a filter, an open silencer, and a piezoresistive vacuum switch measuring relative pressure with high vacuum and standard ejector characteristics. Additional features include a 40 µm grade of filtration, manual override via pushing and operating buttons, a backlit 4-place alphanumeric LCD indicating from -29.5 to 0 inchHg, short circuit and reverse polarity protection, and a standard switching input meeting IEC 61131-2.
