2.1 GENERAL DESCRIPTION
The CAS40P unit is designed for heavy-duty
performance, optimal power consumption, and for use in
areas where installation space is limited.
This type of compressor increases the pressure of the
supply air by reducing its volume. This equipment
operates by taking in successive volumes of air, in
repeated cycles, that is confined in an enclosed space, a
sealed chamber, which then compresses this air mass to
a higher pressure.
The reciprocating air compressor accomplishes this by
using pistons to compress the air inside a set of
cylinders, which confine the air mass. As the pistons
move into the cylinders, the area containing the air mass
decreases and the pressure increases.
The enclosure is constructed of powder-coated,
galvanneal sheet steel to protect the unit. It is designed
so that daily inspections can be accomplished without
removing any panels. However, the panels can be
removed easily for more extensive maintenance and
repairs.
The unit’s steel frame is also powder-coated and has bolt
holes for securing it to a vehicle body mounting platform
or base.

DESCRIPTION
WARNING
DO NOT attempt to service the
equipment while it is operating.
WARNING
Before performing maintenance or repair
operations on the compressor, ensure
that all power has been removed and
locked out to prevent accidental
application.
DO NOT assume that because the
compressor is in a STOPPED condition
that power has been removed.
NOTE
The purpose of this section is to provide
descriptions of key machine components
and systems, and their functions. For
detailed information on servicing the
compressor, consult
