Festo
533975
Air preparation combination unit MSB4N-1/8-FRC7:J3M1
The Festo 533975 is an MS series size 4 industrial component featuring a structural design of a filter regulator with a pressure gauge and a proportional standard oil mist lubricator, operating within a pressure range of 1.5 bar to 14 bar. It provides a 5 µm filtration grade, a manual rotating condensate drain, a plastic bowl guard, and a regulation range of 1 bar to 12 bar at a normal nominal flow rate of 800 l/min using compressed air or inert gases. Controlled via a rotary knob with an integrated lock, this unit maintains constant output pressure with primary pressure compensation, secondary exhausting, and return flow characteristics in a vertical ±5° mounting position.

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.
