Festo
531209
Filter regulator MS4N-LFR-1/4-D7-ERV-AS
The Festo 531209 is an MS-series size 4 filter regulator featuring a structural design with a pressure gauge, a 40 µm filtration grade, and a 19 ml maximum condensate volume. It operates within a 0.2 MPa to 1.2 MPa pressure range, delivers a normal nominal flow rate of 1500 l/min, and incorporates a controller function with constant output pressure, secondary exhausting, and return flow characteristics. Designed for vertical mounting within ±5°, the unit includes both fully automatic and manual non-detenting condensate drains alongside a rotary knob actuator lock with detent closure capabilities.

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.
