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.
When equipped with the low ambient feature, the IQ
System automatically adjusts movable louvers to con-
trol airflow through the aftercooler, ensuring that the
compressed air temperature always remains above
freezing temperatures (typically 45ºF) at any ambient
temperature down to --20ºF. This prevents the need
for 120V AC heat tracing systems, or any manual ad-
justment to prevent freezing of the compressed air
system. All drain points for the condensate handling
system are heated with 24VDC heat tracing, which is
integral to the compressor heater system.
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.
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 selector
valve, the compressed air first enters the aftercooler.
The aftercooler is cooled by the incoming compressor
package air, which is controlled by movable louvers
mounted on the aftercooler (if equipped with low ambi-
ent option). At most conditions, the louvers are fully
open, and maximum aftercooling is available. 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 aero-
sol 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 strainers and constant--bleed orifices, which are
sized to allow the maximum flow of condensate while
minimizing compressed air loss.
The condensate lines are then piped together, and the
condensate is injected at a single point into the engine
exhaust piping. The compressed air then travels
through the minimum pressure valve, and out through
the service air valve. The air pressure gauge on the
instrument panel indicates the pressure inside the
separator tank. A service air pressure gauge is lo-
cated inside the front door of the compressor on the fil-
ter support.
If the IQ System is bypassed (Standard Operation se-
lected), the delivered air pressure will be approximate-
ly equal to the separator tank pressure. If the IQ Sys-
tem operation is selected, the delivered air pressure
will be slightly less, depending on the restriction of the
filters.
