Festo
173810
Filter regulator LFR-3/4-D-7-MAXI-NPT
The Festo 173810 is a Maxi-size industrial component from the D series, featuring a 3/4 NPT pneumatic connection 1 and an operating pressure range of 0.1 MPa to 1.6 MPa (1 bar to 16 bar). Engineered for vertical mounting with either in-line installation or a retaining bracket, this unit handles a normal nominal flow rate of 10000 l/min and provides a 40 µm grade of filtration for compressed air or inert gases. It includes a manual rotating condensate drain with a maximum condensate volume of 80 cm³, a metal bowl guard, and a CRC rating of 2 for moderate corrosion stress within an ambient and medium temperature range of -10 °C 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. 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.
