Festo
531319
Filter regulator MS6N-LFR-3/8-D7-CUM-AS
The Festo 531319 is an MS-series size 6 filter regulator featuring an integrated metal bowl guard, manual rotating condensate drain, and a 5 µm filtration grade. It delivers a normal nominal flow rate of 3500 l/min within an operating pressure range of 0.8 bar to 20 bar, while maintaining a constant output pressure with secondary exhausting and a pressure regulation range of 0.5 bar to 12 bar. Designed with a rotary knob actuator lock and a vertical ±5° mounting position, this component operates on compressed air meeting ISO 8573-1:2010 [-:4:-] or inert gases under moderate corrosion stress.

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.
