Compressor
The compressor assembly is a positive displacement, oil flood lubricated,
helical rotary screw type unit employing a single stage of compression.
The components include housing or stator, two rotors or screws,
bearings and bearing supports.
In operation two helical grooved rotors mesh to compress air. Inlet air
entering the compressor becomes trapped between the lobes of the
rotors. As the rotors turn, this trapped volume of air is reduced in volume
or compressed and is pushed to the discharge end of the compressor.
This process delivers smooth flowing air at full pressure to the receiver.
During the compression cycle, oil is injected into the compressor for the
purposes of lubricating, cooling, and sealing. Compressed air laden with
oil leaves the compressor through a discharge port designed to provide
optimum performance within the desired pressure range.
Air/Oil System
The air/oil system is almost completely contained within the compressor
housing. Within or directly attached to the housing are the air filter, oil
filter and the air/oil separator element.
Air Filter
The air filter is a high efficiency ring style located on top of the inlet valve
of the compressor. It will provide nearly constant efficiency of filtration at
all load conditions. The element has a high dirt holding capacity
for a long life. It is specially treated to be insensitive to heat, cold, water,
and oil.
Oil Filter
The oil filter is a 10-micron spin-on style. It is sized to maintain system
cleanliness and to give good service life. The housing is equipped with a
bypass to insure that there is oil flow on startup. The restriction created
at the filter will have a direct effect on the operating temperature of the
compressor. So you must be sure to maintain it.
Air/Oil Separator
This unit utilizes a spin-on air/oil separator to make maintenance much
more convenient than the element in vessel design. This does not
diminish its operating efficiency. In fact the separation of the element from
the pre-separation tank enhances the performance. The purpose of
the separator is to remove aerosols. The vapor pressure of the oil, the
operating temperature of the unit, operating pressure of the unit and the
operating cycle will affect its performance.
