2.0 INSTALLATION
2.1 VENTILATION
Oil flooded rotary air compressors produce large
amounts of heat. Because of this large heat production,
the compressor must be placed in a room with adequate
ventilation. A room in which the amount of air that is
drawn in and exhausted is equal to or greater than the
cooling fan air flow requirement for the compressor that
is installed.
If heated air from the compressor exhaust is allowed to
recirculate back to the compressor, the compressor will
overheat and shut down. This heat must be exhausted
from the room. You should take this into consideration
when you decide where to place the compressor within
your plant. Consider that the required maintenance
clearance is 3 ft (.9 m) all around the compressor.
However 42” (1.06m), or minimum required by latest
NEC or applicable local codes, must be maintained in
front of control panel.
Ambient temperatures higher than 115°F (46°C)
should be avoided as well as areas of high humidity.
Consider also the environment surrounding or near
the compressor. The area selected for the location of
the compressor should be free of dust, chemicals,
metal filings, paint fumes and overspray.
AIR INTAKE
2.2 FOUNDATION REQUIREMENTS
Refer to the foundation plan for the particular model
compressor to be installed. See Section 8.0.
The compressor can be installed on any level floor that is
capable of supporting it. Compressor weights are listed
on the foundation plans.
When sound transmission is of particular importance it is
often helpful to install a sheet of rubber-fabric-matting, or
cork under the compressor to reduce the possibility of
resonant sounds being transmitted or amplified through
the floor.
2.3 PIPING
The use of plastic bowls on line filters without metal
guards can be hazardous. Their safety can be affected
by either synthetic lubricants or the additives used in
mineral oil. From a safety standpoint, metal bowls should
be used on any pressurized system. Review of your plant
air line system is recommended.
The built-in aftercooler reduces the discharge air
temperature well below the dew point (for most ambient
conditions), therefore, considerable water vapor is
condensed. To remove this condensation, each
compressor with built-in aftercooler is furnished with a
combination condensate separator/trap.
DUST
CHEMICALS
METAL
FILINGS
PAINT
SPRAY
OVERSPRAY
Do not use plastic pipe, soldered copper
fittings or rubber hose for discharge piping.
WARNING
Never elevate the compressor unit
above the floor level. This may allow air
to enter the cabinet under the base.
Performance will be affected.
