Festo
546440
Basic valve LFMB-D-MINI-U
The Festo 546440 is a mini-size fiber filter from Series D featuring a 1 µm grade of filtration, 99.99% overall filter efficiency, and a rotating manual condensate drain within a metal bowl guard. Operating across an input pressure range of 14.5 psi to 232 psi (0.1 MPa to 1.6 MPa), it processes compressed air as per ISO 8573-1:2010 [6:4:4] or inert gases to deliver an output air quality class of ISO 8573-1:2010 [5:4:3]. This component accommodates a maximum condensate volume of 0.744 US fl oz, supports medium and ambient temperatures ranging from 14 °F to 140 °F, and offers in-line installation or accessory mounting with moderate corrosion resistance (CRC 2).

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.
