Festo
531234
Filter regulator MS4N-LFR-1/8-D6-CRV-AS
The Festo 531234 is an MS-series size 4 filter regulator featuring a structural design with a pressure gauge, a 5 µm filtration grade, and a 75% degree of condensate separation with a maximum condensate volume of 19 ml. It incorporates a fully automatic and manual non-detenting condensate drain, a rotary knob actuator lock with detent that can be closed with accessories, a plastic bowl guard, and operates within a pressure regulation range of 0.3 bar to 7 bar at an operating pressure of 0.2 MPa to 1.2 MPa. Designed for vertical ±5° mounting with a normal nominal flow rate of 900 l/min, it provides constant output pressure with secondary exhausting and return flow characteristic for compressed air per ISO 8573-1:2010 [7:4:-] 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.
