This is 3 Stage Compressor driven by Flame Proof Motor and lubricated by flash and forced lubrication system. The compressor along with interstage coils and purge vessels are immersed in a water filled tank to avoid in any pressurized acetylene to come in contact with air and also to make sure that all the components are continuously cooled. The third stage pressure is determined by the setting of backpressure regulating valve.
