Festo
173866
Service unit FRC-1/2-D-7-MIDI-NPT
The Festo 173866 is a Midi-sized industrial component featuring a 40 µm filtration grade, a manual non-detenting condensate drain, and a 0.5 bar to 7 bar pressure regulation range operating within 1 bar to 16 bar pressure limits. Weighing 1440 g with 1/2 NPT pneumatic connections on both ports, this unit supports a normal nominal flow rate of 2800 l/min for compressed air as per ISO 8573-1:2010 [-:9:-] and inert gases across a medium and ambient temperature range of -10 °C to 60 °C. It offers alternative mounting via in-line installation or a retaining bracket, features a moderate corrosion resistance class of CRC 2, and requires oil lubrication for further operation.

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.
