Festo
538831
Vacuum generator OVEM-05-H-B-QO-CE-N-2P
The Festo 538831 is a modular industrial component featuring a 0.45 mm nominal width Laval nozzle, a 20 mm width dimension, an open muffler construction type, and an any mounting position. It incorporates an electric ejector pulse valve, flow control valve, electric on-off valve, filter, electric air-saving function, check valve, open muffler, vacuum switch, and a piezoresistive relative pressure measuring principle with a -0.999 bar to 0 bar display range on a 4-digit alphanumeric backlit LCD. This unit delivers high vacuum and standard ejector characteristics with 40 µm filtration, non-detenting and control-key manual override, short-circuit and reverse polarity protection, N.C./N.O. switching element functions with window or threshold value comparators, and IEC 61131-2 compliant switching inputs.

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.
