AIR DRYER (OPTION)
Function of air dryer
Since moisture contined in the atmos-
phere is compressed and warmed by
the air compressor, the amount of
moisture is in proportion to that of
compressed air.
This hot and humid air is cooled
down in reserve tanks or pipings to
form condensation. This condensation
washes away lubricants from the
moving parts of various devices or
equipment, resulting in unsatisfactory
actions of these devices or equip-
ment. In addition, impurities contained
in the condensation accelerates rust-
ing action to shorten the lives of relat-
ed devices or equipment. In cold
weather, this condensation can be
frozen and immobilize various devices
and equipment. Therefore, it is essen-
tial to remove moisture from com-
pressed air in order to extend the
service lives of devices, to enhance
reliablilty, and to prevent possible
damage or breaks.
