HP300 IQ System
The IQ System is a complete, self--contained system
which provides cooler, cleaner air than from a
standard portable compressor. The system utilizes an
integral aftercooler, high--efficiency filtration, and a
patented condensate disposal system to provide the
cool, clean air. The condensate disposal system
injects all liquid condensed from the moisture
separator and filters into the engine exhaust system
where it is vaporized by heat. This eliminates the need
for collecting the condensate, and the added cost of
disposing of the condensate, which is often regulated
by local, state, and/or federal regulations.
Theory of Operation
The compressed air exits the separator tank through
the top cover piping, and can then travel along one of
two paths, selectable via manual valving. Refer to
Illustration 36535177.
One path allows Standard Operation, which bypasses
the IQ System, and delivers air quality equivalent to a
standard oil--flooded portable compressor. If the IQ
System is enabled by proper setting of the 3--way
valve, the compressed air first enters the aftercooler.
The aftercooler is cooled by the incoming compressor
package air. The compressed air and condensate
(water with a small amount of compressor lubricant)
exits the aftercooler and enters the moisture
separator, where most of the condensate is removed.
The compressed air then flows through two stages of
filtration, where the aerosol water and oil is removed
down to approximately 0.01 ppm, and all particulates
are removed down to 0.01 micron.
At the bottom of the moisture separator and both filters
are condensation lines.
These condensate lines are piped together, and the
condensate is injected at a single point into the
exhaust system. The compressed air then travels

through the minimum pressure valve, and out through

The air pressure gauge on the instrument panel
indicates the pressure inside the separator tank. The
air pressure gage located at dual filters on lifting bail
indicates delivered air pressure of the IQ System.
If the IQ System is bypassed (Standard Operation
selected), the delivered air pressure will be
approximately equal to the separator tank pressure.
If the IQ System operation is selected, the delivered
air pressure will be slightly less than separator tank
pressure depending on the restriction of the filters,
