Festo
543641
Diaphragm air dryer MS6-LDM1-1/4-P20-Z
The Festo 543641 is a size 6 industrial component from the MS series featuring a membrane dryer design structure with a standard nominal flow rate of 200 l/min and a working pressure ranging from 3 to 12.5 bar. Constructed with an aluminum die-cast housing and a wrought aluminum alloy bowl, this unit requires a vertical assembly position within +/- 5° and operates with compressed air according to ISO8573-1:2010 [1:4:2], though lubricated operation is not possible. It achieves a pressure dew-point reduction of 20 K, delivering an air purity class at output to ISO8573-1:2010 [1:3:2] with medium and ambient temperatures between 2 and 50 °C. The component weighs 1.05 kg, includes G1/4 pneumatic connection ports, features CRC 2 corrosion resistance, and supports optional line installation or mounting with accessories while conforming to RoHS materials notes.
