Frequent Asked Question

1. What is fixed speed compressor?

A fixed-speed air compressor operates by supplying a consistent — or fixed — voltage and frequency to its motor, which in turn drives its rotary screws at a consistent speed to draw in and pressurize air.To adjust the airflow, the fixed-speed air compressor needs to adjust the air inlet valve to let more or less air out. So the disadvantage is even when the air demand is low, the motor always operates at the same speed, so it is a waste of energy.

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 fixed speed compressor size?

Flow, often measured in cubic feet per minute (cfm), or cubic meters per minute (m3/min), is determined by time. Determining the right flow of a fixed screw compressor depends on how long you need to get a job done.
Pressure, measured in pounds per inch (psi) or bar, is all about force. How much pressure you need depends on the resistance of a task. If you need to move heavy objects, you’ll need higher pressure.

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.
