Efficient Screw Compression

Unlike Roots blowers that rely mainly on external compression, the screw blower uses internal compression to improve operating efficiency and reduce energy loss.

The optimized screw rotor design provides smoother airflow, lower pulsation and more stable pressure, making it suitable for long-term industrial operation.

Typical Applications

Suitable for:

• Wastewater Treatment
• Sewage Aeration
• Pneumatic Conveying
• Cement Industry
• Chemical Processing
• Textile Industry
• Food Processing
• Power Plants
• Aquaculture
• General Industrial Air Supply

For applications requiring large airflow, low pressure and continuous operation, the permanent magnet VSD oil-free screw blower provides an energy-efficient and reliable alternative to traditional Roots blowers.
