Festo
546448
Basic valve LFMB-D-MAXI-U
The Festo 546448 is an industrial component featuring a Maxi size D-series fiber filter with a 1 µm filtration grade and a manually rotating condensate drain. It operates within a pressure range of 0.1 MPa to 1.6 MPa (1 bar to 16 bar or 14.5 psi to 232 psi) using compressed air conforming to ISO 8573-1:2010 [6:4:4] or inert gas, while delivering an output air quality class of ISO 8573-1:2010 [5:4:3]. Equipped with a metal bowl guard and a 2.7 US fl oz maximum condensate volume, this unit maintains a 99.99% filter efficiency with a moderate corrosion resistance class (CRC 2) and operates at a medium and ambient temperature range of 14 °F to 140 °F.
