• Tank-mounted CR with electric motor: The compressor on a horizontal or vertical air receiver with air
outlet valve, pressure gauge, pressure relief valve, air pressure switch with an on/off button (MDR), and
condensate drain valve.
• Tank-mounted CR with gas engine: The compressor on an air receiver with air outlet valve, pressure

• CR base-mounted unit is a fully operational unit with air pressure switch and on/off switches mounted

• CR Contractor units are mobile compressors. They are equipped with a gas engine. The compressors
have two outlet connections:
• A connection for compressed air at working pressure.
• A connection for compressed air at reduced pressure via a pressure regulator.
2.2 Hour meter option
The hour meter is triggered by the motor’s magnetic field, so the hours display actual operation. When the
motor is on, the hours icon will blink on/off indicating the hour meter is active.
With solid-state technology the hour meter is built with a custom chip and with solid construction for
maximum durability for harsh environments and rugged applications.
