Stationary

LW 450 E

Robust, low RPM units with low maintenance and running costs for the user. Pneumatic/electric compressor control with final pressure cut off and automatic condensation drain ensures easy and trouble free operation. The compressors are ideal for continuous operation and a favourite choice for overseas diving centers with very long service intervals [e.g. replacement of concentric suction/pressure valves (3) every 6000 hours!].
