How Does the CPM 3–7 HP Screw Air Compressor Work?
The CPM Series uses advanced rotary screw technology to deliver a continuous, efficient, and reliable supply of compressed air. Here’s how the process works:
Step 1 – Air Intake
Ambient air enters the compressor through the air intake filter, where dust and contaminants are removed.
Step 2 – Air Compression
Two precision-engineered rotary screws compress the filtered air, creating a smooth and continuous airflow.
Step 3 – Cooling & Lubrication
Oil is injected into the compression chamber to cool, lubricate, and seal the rotors for efficient operation and longer component life.
Step 4 – Oil Separation
The compressed air passes through an oil separator, ensuring clean compressed air with minimal oil carryover.
Step 5 – Air Delivery
The compressed air is stored in the receiver tank (if equipped) and supplied at a stable pressure to power your pneumatic tools and industrial equipment.
This layout works exceptionally well as a 5-step horizontal timeline or vertical process with icons, making it easy for industrial buyers to understand the compressor’s operation at a glance.
