Intake and Control System

It filters any harmful dusts that may be sucked by the compressor from the external environment, so
that the compressor works at the preset pressure interval. This system comprises of two
subassemblies, i.e. the Intake System and the Intake Control System.

3.3.1 Intake System

The abrasives in the air drawn by the compressor enter any point where the oil penetrates in
the compressor, and abrades the surfaces it contacts. The bearings life, O-rings and seals are
rapidly shortened as a result of the increased friction. Furthermore, the filters clogged by dust suck
less air. Due to blockade, both the cooling and intake air quantities are reduced, so that the
compressor capacity is diminished with the operating temperature rising. The higher operating
temperature has adverse effects on all the internal parts and components of the compressor. The
hoses are hardened, the bearings are worn, and the oil id degraded in shorter times. Hence, the
failure in handling regular and timely cleaning and maintenance does not allow saving, but results in
higher power consumption and increased operating costs. The intake system comprises of a panel
filter outside the compressor, and an air filter and connection hoses inside the compressor.
