Note:

Model number remarks: “F” as fixed speed, “V” as VSD. Due to the potentially different rotation speeds of motors, the air flow rates of fixed speed represent the minimum in the range (i.e 30kW 8 bar 5.67m³/min), while VSD can reach the maximum at full loading.
Standard voltage in 380V (+/-10%), 50Hz +/-2% and available for customized voltage 220/380/440/460V/60Hz.

In cases of elevated altitudes, extreme temperatures, excessive humidity, heavy dust exposure, or any other challenging operational environments, we can offer tailored product designs to meet your specific needs. Customization is available to align with your unique requirements.

Frequently Asked Questions

What is permanent variable speed rotary screw air compressor?

A permanent variable speed rotary screw air compressor utilizes a permanent magnet synchronous motor, which does not require reactive magnetizing current and can significantly improve power factor (up to 1, even capacitive), reducing stator current and resistance losses. Additionally, there is no rotor loss during stable operation, which can reduce fan (even eliminating it in small capacity motors) and corresponding windage losses, resulting in an efficiency improvement of 2-8 percentage points compared to a regular motor of the same specifications.

Why choose high end permanent variable speed rotary screw air compressor?

High-end permanent variable speed rotary screw air compressors offer a range of benefits, including energy efficiency, reduced maintenance costs, and improved air quality. Compared to the normal type, the high end permanent a longer lifespan and can handle heavy-duty industrial applications with ease. While they may have a higher upfront cost, the long-term savings and benefits make them a worthwhile investment for many businesses.
