1-7. Equipment Characteristics, Capabilities, and Features. The compressor unit is driven by a two cylinder, air
cooled, diesel engine connected to a four stage, reciprocating, air cooled, compressor. It is designed for continuous
operation at a rated capacity of 20 cfm at pressures up to 3200 psi (22,064 kPa). It is also designed to operate under
extreme climatic conditions. The K-20-D Compressor Unit is a portable, self contained skid mounted unit. The frame is
constructed of welded steel channel. The subframe is attached to the main frame by 10 anti-vibration mounts.
Slinging/Tie-downs for hoisting or securing the compressor unit are welded to the skids and located at the four corners of
the skids.
