Pressure Modulation Control (PMC) Assembly

Feature

Description

1 Pressure sensor

This activates the pressure switch when the PMC reaches a predetermined pressure.

2 Blowdown valve

This bleeds off any remaining air in the system when it shuts down.

3 Pressure regulator

This regulates the air circuit in fixed mode and limits the system's maximum pressure in auto mode.

4 Manual adjustment screw

This calibrates the air pressure in fixed mode.

5 Mounting bracket

This is used to mount the PMC on the compressor assembly.
