Product Description

Quiet High Pressure Oil-Free Air Compressor for PET Manufacturing

Our high pressure air compressor system includes the main engine, motor, water cooler, separator, and instrument cabinet fixed on a single base. The integrated pipeline system connects all components into a high-performance, compact compressor unit.

Three-Stage Compression Technology: The first stage uses a screw compressor (up to 0.8MPa), followed by second and third stage oil-free piston boosters reaching 2.0~4.0MPa. This ensures the gas is clean, colorless, and odorless.
