3.1 IK150 II and IK180 II Compressor Blocks
3.1.1
Description
The IK150 II and IK180 II compressors are used to compress air up to 5000 psi.
Both compressors are four cylinder, four stage air cooled, oil lubricated reciprocating compressors. The
4th stage cylinder is lubricated by means of the forced feed lubrication system, while the other cylinders
are splash lubricated. The cylinders are arranged 90° apart, with the 1st and 2nd stage, and the 3rd and 4th
stage opposite each other. These compressor blocks are particularly suitable for continuous operation
because of their rugged design and corrosion resistant intermediate filter and cooler assemblies.
