Festo
540001
Vacuum generator OVEM-14-H-BN-QO-CE-N-2P
The Festo 540001 is a modular industrial component featuring a 1.4 mm nominal size Laval nozzle, a 20 mm grid dimension, an open silencer design, and an ejector characteristic optimized for high vacuum and standard operation. This unit integrates a filter, non-return valve, flow control valve, electrical on-off valve, electrical ejector pulse valve, electrical air-saving circuit, vacuum switch, and an open silencer while supporting assembly in any position with 40 µm filtration. Operational control is managed via a piezoresistive relative pressure measuring principle with short-circuit strength, polarity protection for all electrical connections, IEC 61131-2 standard switching input, manual override via pushing and operating buttons, and a backlit 4-place alphanumeric LCD display indicating -29.5 to 0 inchHg.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
