Festo
8098258
Filter regulator MS4-LFR-1/4-D6-E-P-M-AG-BAR-B
The Festo 8098258 is an industrial Size 4 filter regulator from the MS series featuring a rotary knob with detent, manual rotating condensate drain, and an integrated pressure gauge displaying in bar and psi. Built with a directly controlled piston regulator, it delivers a normal nominal flow rate of 1700 l/min within an operating pressure range of 1 bar to 10 bar and a pressure regulation range of 0.3 bar to 7 bar. This component provides a 40 µm filtration grade, 75% condensate separation, 16.5 ml max condensate volume, constant output pressure with secondary exhausting, and return flow characteristics for compressed air per ISO 8573-1:2010 [7:4:4] 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.
