Festo
531311
Filter regulator MS6N-LFR-1/4-D6-CRV-AS
The Festo 531311 is an MS-series size 6 filter regulator featuring a structural design with an integrated pressure gauge, a 5 µm grade of filtration, and a maximum condensate volume of 38 ml with a 75 % condensate separation degree and fully automatic or manual non-detenting condensate drain. It provides a normal nominal flow rate of 2700 l/min, a pressure regulation range of 0.3 bar to 7 bar within an operating pressure of 2 bar to 12 bar, and a constant output pressure controller function with secondary exhausting. The unit includes a plastic bowl guard, a rotary knob actuator lock with detent that can be closed with accessories, and operates within a vertical ±5° mounting position using compressed air or inert gases.

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.
