FAQ

Q: What is it and what are its differences from fixed speed air compressor?

A: Adjustable speed air compressor adopts VSD technology to adjust motor speed matching actual air consumption, while fixed speed compressor runs at constant speed and adjusts air volume only by loading and unloading mode. VSD compressor eliminates no-load power loss with up to 35% energy saving, softer startup and more stable air pressure, which is more suitable for sites with unstable air demand.

Q: How about its energy saving performance? Are the data authentic?

A: Equipped with original Atlas Copco VSD frequency conversion technology, verified by long-term practical tests and comparison experiments, it can save energy up to 35% compared with traditional fixed speed compressors. All data are tested in accordance with ISO 1217 standard with high authenticity.

Q: What is the maximum operating ambient temperature?

A: Equipped with W-fin heat dissipation system and high temperature thermostat valve, it can run continuously and stably under ambient temperature up to 46℃, adapting to high temperature seasons and harsh working environments.

Q: Is daily maintenance difficult? What is the regular maintenance cycle?

A: Core components adopt quick disassembly structure for easy daily inspection and replacement. The regular maintenance cycle is about 2000 to 4000 hours, which varies according to actual working conditions and lubricant quality.

Q: Does it support remote monitoring and fault alarm function?

A: Yes. It is equipped with Elektronikon intelligent controller and SmartLink remote system, supporting real-time operating parameter monitoring, abnormal fault alarm and maintenance reminder to realize unattended management.

Q: What installation methods are available? Does it occupy large space?

A: Floor-mounted and tank-mounted two installation types are optional. The standard G7-15VSD model dimension is only 770×620×970mm with compact structure, saving much installation space.

Q: What pressure and flow range can it cover?

A: Standard working pressure ranges from 3.5bar to 10bar(e), and air flow covers 0.38 to 3.92m³/min within G7-22VSD series, fully meeting air supply demands of medium and small-scale industrial production.
