Festo
8175800
Filter regulator MS4-LFR-1/4-D6-E-P-M-A8-F1A-B
The Festo size 4 industrial component from the MS series is a filter regulator featuring a directly controlled piston regulator, a rotary knob with detent for actuator locking, and a manual rotating condensate drain. It provides a normal nominal flow rate of 1700 l/min within an operating pressure range of 1 bar to 10 bar, achieving 75 percent condensate separation with a 40 µm filtration grade and a 16.5 ml maximum condensate volume. Certified with a corrosion resistance class of 1, VDMA24364-B1/B2-L LABS conformity, and ISO 14644-1 Class 7 cleanroom suitability, this unit is also applicable for the production of Li-ion batteries with reduced Cu/Zn/Ni values.

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.
