Festo
526289
Filter regulator LFR-QS4-D-7-5M-MICRO
The Festo 526289 is a micro-sized Series D filter regulator with an integrated pressure gauge, featuring a 5 µm filtration grade and a manual rotary condensate drain with a maximum condensate volume of 3 cm3. It operates within a working pressure range of 1 to 10 bar and a pressure regulation range of 0.5 to 7 bar, delivering a standard nominal flow rate of 170 l/min for compressed air to ISO 8573-1:2010 [7:9:-] and inert gases. Designed for vertical assembly within +/- 5° via line installation or optional accessories, this 124 g component includes a rotary knob with a lock and maintains a moderate corrosion stress classification CRC of 2 across medium and ambient temperatures of -10 to 60 °C.

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.
