Festo
543661
Membrane air dryer MS6N-LDM1-3/8-P40-Z
The Festo 543661 is an MS-series size 6 membrane dryer featuring 3/8 NPT pneumatic connections for both connection 1 and connection 2, engineered for vertical ±5° mounting via in-line installation or accessories. It operates within a 3 bar to 12.5 bar pressure range, delivering a normal nominal flow rate of 400 l/min and a pressure dew point reduction of 20 K for compressed air conforming to ISO 8573-1:2010 [1:4:2]. This 1.3 kg component maintains a medium and ambient temperature range of 2 °C to 50 °C, provides an output air quality class of ISO 8573-1:2010 [1:3:2], and achieves a moderate corrosion resistance class (CRC 2) with VDMA24364-B2-L LABS conformity.
