Festo
546439
Basic valve LFMA-D-MINI-U
The Festo part number 546439 is a mini-sized structural fiber filter from the D series, featuring a 0.01 µm grade of filtration and a manual rotating condensate drain. It operates within a pressure range of 0.1 MPa to 1.6 MPa (1 bar to 16 bar) utilizing compressed air per ISO 8573-1:2010 [6:4:4] or inert gases, and delivers an output air quality class of [3:4:2] with a 99.9999% filter efficiency. This component includes a metal bowl guard, a CRC rating of 2 for moderate corrosion stress, and supports in-line installation or mounting with accessories across a medium temperature range of 33.8 °F to 140 °F and an ambient temperature range of 14 °F to 140 °F.
