How Does the CPI 75–120 HP Screw Air Compressor Work?

The CPI Series utilizes advanced rotary screw technology and a high-efficiency gear-driven transmission to deliver a continuous supply of compressed air for demanding industrial operations.

Step 1 – Air Intake

Ambient air is drawn through a high-performance intake filter to remove dust and contaminants.

Step 2 – Air Compression

Twin precision-engineered rotary screw elements compress the air efficiently, producing a stable and high-volume airflow.

Step 3 – Gear-Driven Power Transmission

The gear-driven system transfers power directly to the air-end with minimal energy losses, maximizing compressor efficiency.

Step 4 – Cooling & Oil Separation

Oil cools and lubricates the compression chamber before being separated to ensure clean, high-quality compressed air.

Step 5 – Air Delivery

Compressed air is delivered at consistent pressure to support production lines, industrial machinery, and pneumatic systems without interruption.
