Abstract
A system and method for controlling air flow into a rotary screw compressor is provided. The system includes an unloader valve for controlling airflow into the compressor. An anti-rumble system may be included in the unloader valve housing. The unloader valve is an air operated sleeve-type valve. The anti-rumble system includes an integrated vent path for the discharge side of the compressor. All moving parts are sealed within the unloader housing to prevent malfunction due to dirt entering the mechanism.
