Frequent Asked Question

1. What is fixed speed compressor?

A fixed-speed air compressor is a device that compresses air by using rotors with helical teeth that mesh together in opposite directions to pressurize the gas. It operates at a constant frequency, meaning the motor speed does not adjust based on air demand. Therefore, for customers with energy-saving needs, a permanent magnet variable frequency air compressor is a more ideal choice. It can adjust the motor speed according to actual demand, achieving higher energy efficiency.

2.What is the difference between VSD and fixed speed compressor?

The fixed speed air compressor is based on the standard AC power of the national grid, which is fixed and unchangeable, and the relative main engine speed is also unchangeable.
VSD is to add frequency converter on the basis of industrial frequency machine to realize frequency conversion, the frequency can be large or small, using the frequency regulation to control the main engine speed. Achieve the effect of energy saving and power saving without idle load.

3.How to select screw compressor ?

Please provide the required power (KW) and pressure (bar) for the screw air compressor.
Please provide the voltage (V) and frequency (Hz) specifications.
Please specify the intended application for the screw air compressor.
Please provide details of your working environment (humidity conditions, dust levels).
Please share the local electricity rate (per KWh).

In this way, we can provide you with a comprehensive gas solution.

4.what about quality warranty?

1 year warranty for whole machine and 2 years warranty for the air end except consumables.

5.Should I use a fixed-speed or variable-speed air compressor?

If the requirements for the air pressure used are not high, and the air volume generated by the selected air compressor is close to the required air volume, it is recommended to use the fix speed.
If your power supply costs are high, the compressor runs for many hours a day, and your needs vary widely, then VSD makes sense. In addition,a clean, dry installation area and good power supply are required for VSD.

6.How about your delivery time？

Our standard delivery time for permanent magnet variable frequency air compressors is typically between 4 to 6 weeks, depending on the specific configuration and customization requirements. However, we strive to accommodate urgent orders, so please feel free to discuss any time-sensitive needs with us, and we will do our best to expedite the process.
