Installation and operation
5.1.4 Site requirements
 Install the air compressor in a clean, dry, cool, and dust
free room as extreme temperatures (hot or cold),
moisture, and airborne contaminants can significantly
affect compressor performance, durability, and
compressed air quality.
 Be aware the entrance to the compressor room should
be high enough and wide enough to carry the
compressor in and out.
 Leave a minimum of 1m (3.28ft) space around the
compressor for safe and proper inspection, cleaning,
and maintenance activities.
 Leave a minimum of 2m (6.56ft) space above the
compressor for hot air to flow away from the
compressor.
 Ensure the compressor is protected against direct
sunlight and rain.
 Avoid exposing the compressor to excessive moisture
(from rain, dryer vent, etc.) as moisture can affect
airend lubrication, promote rust formation on the
compressor, and lead to electrical problems of the
motor.
 Neither install the machine in a location where flame is
used nor place any inflammable objects near the
compressor.
 Ensure the room temperature is within 45
o
C (113
o
F), as
high ambient temperatures will result in reduced oil life
due to higher discharge oil temperature (DOT). It also
results in high approach temperatures affecting the
cooling and condensation efficiency in the after-cooler
and in air treatment equipment like air dryers.
 Ensure the hot medium of other utility equipment like
gensets/dryers/ boilers, etc., is not sucked by the
compressor inlet or that in any way the room
temperature does not rise to prevent high discharge oil
temperature.
 Ensure the ambient temperature does not drop below
0
o
C (32
o
F). Provide air supply openings and adjustable
louvers to ensure that the minimum temperature does
not drop down below 0
o
C (32
o
F).
 Install the compressor on a smooth, solid, level
industrial concrete floor capable of bearing the weight of
the compressor. Ensure unevenness of the surface is
within 6mm (0.25") and taper is within 50 per meter.
 If the floor is splashed frequently with water while
cleaning, then place your compressor on a raised
concrete plinth 100 to 150 mm (4 to 6 inches) high.
 Ensure the compressor base makes 100% contact
directly with the floor.
 Know that an industrial floor with a level surface
capable of supporting the weight of the compressor is
sufficient for installing your compressor. No special
foundation or anchoring is necessary for rotary screw
compressors.
 Do not store toxic, volatile, or corrosive agents near the
compressor.
 Isolate the compressor from corrosive agents like
ammonia, chlorine, salt spray, and other chemicals as
these may erode the internal components and also
contaminate the oil and filters.
 Do not allow hot air from additional equipment to blow
towards the compressor.
 If you operate in high dust applications like rice mills,
cement, flour mills, etc., clean and replace the filters
more often.
 Good practice is to have overhead lifting in the
compressor room to facilitate any major overhaul. If an
overhead hoist is not available, you should be able to
use a mobile crane or forklift truck in your compressor
room at a minimum.
5.1.5 Ventilation and exhausting hot air
 Ensure adequate ventilation in the compressor
installation area. Your compressor has a ventilating air
requirement of 600 to 1200 cfm.
