CONTROLS & INSTRUMENTATION
GENERAL DESCRIPTION - The rotary screw compressor package is prewired with all controls, motor
and starter for the voltage and horsepower at the time of ordering. It is necessary only to connect the
compressor unit to the correct power supply and the shop air line. A standard compressor package
consists of the compressor, air/oil reservoir, oil cooling system and filter, motor, starter/control box and
control components.
This compressor unit features the AIRPILOT ELECTRONIC CONTROLLER, which integrates all the
control functions under microprocessor control. Its functions include safety and shutdown, compressor
regulation, operator control, and advisory/maintenance indicators. The keypad and display provide the
operator with a logical and easily operated control of the compressor package and indication of its
condition.
