    Operation & Maintenance Manual Options 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 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.

  • Page 107: Options

    Options Operation & Maintenance Manual After removing the condensate and filtering, the compressed air then travels through IQ Minimum Pressure Valve and out through the IQ Service Air Valve (see IQ System Configuration later in this section). The Air Pressure Gauge on the instrument panel indicates the pressure inside the Separator Tank.
