Festo
546446
Basic valve LFMA-D-MIDI-A-U
The Festo 546446 is a Midi size industrial component from Series D featuring a fiber filter structural design with a 0.01 µm grade of filtration and fully automatic condensate drain. It operates at a pressure range of 0.2 MPa to 1.2 MPa (2 bar to 12 bar) with compressed air as per ISO 8573-1:2010 [6:4:4] or inert gases, delivering an output air quality class of ISO 8573-1:2010 [3:4:2]. Equipped with a metal bowl guard, a corrosion resistance class of CRC 2, and VDMA24364-B1/B2-L LABS conformity, this unit achieves a 99.9999% filter efficiency across a medium and ambient temperature range of 14 °F to 140 °F.

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.
