Festo
531230
Filter regulator MS4N-LFR-1/8-D6-CRM-AS
The Festo size 4 industrial component from the MS series is a filter regulator featuring an integrated pressure gauge, a 5 µm filtration grade, and a manual rotating condensate drain with a 19 ml maximum condensate volume. Designed with a constant output pressure controller function, secondary exhausting, and a return flow characteristic, this unit operates within a 0.8 bar to 14 bar pressure range and a 0.3 bar to 7 bar regulation range at a normal nominal flow rate of 900 l/min. It includes a plastic bowl guard, a rotary knob actuator lock with detent that can be closed with accessories, and requires a vertical ±5° mounting position for compressed air or inert gas media.

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.
