Festo
173766
Filter regulator LFR-1/4-D-O-MINI-NPT
The Festo part number 173766 is a mini industrial component from the D series featuring a 1/4 NPT pneumatic connection 1 and a 40 µm filtration grade. This unit handles an operating pressure range of 0.1 MPa to 1.6 MPa (1 bar to 16 bar) with a normal nominal flow rate of 1400 l/min and supports a maximum condensate volume of 22 cm³ drained via a manual, non-detenting mechanism inside a metal bowl guard. Operating within a temperature range of -10 °C to 60 °C, the component weighs 410 g and accommodates either in-line installation or mounting with a retaining bracket for compressed air or inert gases per ISO 8573-1:2010.

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.
