Filter regulator MS4-LFR-1/4-D7-C-R-M-VS-AS
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 filtration grade, and a manual rotating condensate drain with a 19 ml maximum volume capacity. It delivers a normal nominal flow rate of 1200 l/min using compressed air according to ISO 8573-1:2010 [-:4:-] or inert gases, operating within a pressure range of 0.8 bar to 14 bar and a regulation range of 0.5 bar to 12 bar. Equipped with a plastic bowl guard, a rotary knob with detent that can be closed with accessories, and a constant output pressure controller function with secondary exhausting and return flow characteristics, this unit maintains a maximum pressure hysteresis of 0.25 bar under a moderate corrosion stress rating of CRC 2.

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.
