TWO THROWS UNIT

TP 100 Series

The Two Throw version of the Knox-Western TP class frame is another one of our precision balanced machines capable of 1800 RPM with vibration free operation. As with all Knox-Western compressors, the Two Throw frame with its rugged construction was designed to operate in hostile environments with available features such as double compartment distance pieces, special materials of construction, and full flow oil filtration. Capable of one or two stages of compression.
