Variable Speed Compressors are also know as changeable speed drive compressors, and are air compressors that take benefit of changeable speed drive technology. They employ a special drive which controls the Rpm (Revolutions Per Minute) speed of the compressor, and this in turn saves vigor when compared to its fixed speed equivalent.
The most tasteless form used in the air compressor commerce uses a variable-frequency drive, and this is used to convert the Ac input power to Dc and then back to a quasi-sinusoidal Ac power, with the use of an inverter switching circuit.

The main benefits are, reduced power cost, reduced power surges, and the delivery of more constant pressure. The downside is the heavy charge of the drive and their sensitivity to heat and moisture.
They combine a speed inverter, which converts the Ac signal to Dc and speeds up or slows down the motor, with a pressure transducer to indeed match the compressed air output to demand. The vigor efficiency of these compressors results in worthwhile savings on vigor costs for users with ranging compressed air requirements. The demands for air in nearly every compressed air system fluctuate to some extent. If a compressor has a fixed speed, then it means that it will be switching on and off and probably running inefficiently.
As vigor costs have increased it has come to be more cost productive to use these compressors. These types of compressors will only furnish the volume of compressed air required and can be a very productive way of recovery energy. If more than one fixed compressor is used, it may be more cost productive to have only one compressor to deal with the changeable part of the air demand. Studies have proven that better control, housekeeping and maintenance could save operators up to one third of the vigor used across their compressed air systems.
There are other types of air compressors and these can include:
o Rotary screw compressors
o changeable speed compressors
o Vane compressors
o Reciprocating compressors
With the focus on reducing your carbon footprint, changeable speed technology can sacrifice electrical running costs whilst maintaining system reliability.
