Festo 531300 MS6N-LFR-1/2-D6-ERV-AS – Filter Regulator, 1/2 NPT, 40 µm, 0.3–7 bar, Automatic Drain
The Festo 531300 (type MS6N-LFR-1/2-D6-ERV-AS) is a filter regulator from Festo’s modular MS series, size 6. It is the MS6N version with NPT threads, which Festo offers for the North American market. One compact unit filters and regulates the compressed air. Its 40 µm filter element removes particles and condensate, and the regulator holds the outlet pressure steady across an adjustable range of 0.3 to 7 bar.
This version has a plastic bowl with plastic bowl guard and a fully automatic, normally open condensate drain, so the bowl empties without operator attention. It has an integrated pressure gauge, and the rotary knob can be locked using accessories. The 531300 suits standard factory air systems with 1/2 NPT piping, especially where the filter regulator must run without regular manual draining.
