Features

Air End

The high durability and reliability of screw air end, the heart of air compressor.

The new generation of this screw compressors includes:

The latest casting technology is adopted to integrate various oil circuits and passages to reduce leakage points.
Using the world's leading asymmetrical screw type.
The long-tested bearing life of the compressor effectively prolongs the service life of the screw compressor and reduces the overall maintenance cost of your screw compressor.

Motor

TEFC enclosed high-efficiency motor, energy efficiency center certified IE3 motor.

Heavy-duty designed low-speed motors, which have longer bearing lifetime than high-speed motors.
Optional with IE4/IE5 motor.

Multiple Control Methods

Spiral Valve

The market-proven technology of spiral to control air capacity.

VSD Control

The most optimized VSD control system. It can adjust the speed of the air end by a wide range of regulation (the air volume adjustment range is up to 75%) to meet the changes in your air consumption.

Sprial Valve Technology (Optional)

Compressor with spiral valve feature a variable displacement Air End. Compression volume is varied to suit air demand by progressively opening or closing internal bypass ports on the Air End. And compression chamber closed bypass ports utilize the entire length of the rotor.

Capacity is matched to system demand - prevent the wastage of air.
Up to 55% turndown capability with spiral valve.
As compared to other compressors using suction throttling, or load/no load control, power saving up to 10% at part load conditions.
