Festo
546444
Basic valve LFMB-D-MIDI-U
The Festo 546444 is a Midi-size fiber filter from the D series featuring a manual rotating condensate drain and a metal bowl guard. Operating within a pressure range of 0.1 MPa to 1.6 MPa (1 bar to 16 bar / 14.5 psi to 232 psi), this component processes compressed air and inert gases according to ISO 8573-1:2010 [6:4:4] while achieving a 99.99% filter efficiency and 1 µm filtration grade. It operates at medium and ambient temperatures between 33.8 °F and 140 °F, offering moderate corrosion resistance (CRC 2) and VDMA24364-B1/B2-L LABS conformity for in-line or accessory-mounted installations.

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.
