Filter regulator MS4-LFR-1/8-D7-C-R-M-AD13-AS-WR
The Festo Size 4 industrial component from the MS series is a filter regulator featuring a structural design without a pressure gauge, a 5 µm grade of filtration, and a manual rotating condensate drain with a 19 ml maximum volume. It delivers constant output pressure across an operating pressure range of 0.8 bar to 14 bar with a normal nominal flow rate of 850 l/min, secondary exhausting, and a return flow characteristic. Operating on compressed air per ISO 8573-1:2010 [-:4:-] or inert gases, the unit incorporates a plastic bowl guard and a rotary knob actuator lock with detent that can be closed with accessories.

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.
