6 FAQs about [Variable frequency screw air compressor low frequency use]

What is a variable speed drive compressor?

Variable speed control Variable speed drive (variable frequency drive) compressor controls use a frequency drive to control the frequency of the electrical signal to the motor. This, in turn, varies the speed of the motor and airend, controlling capacity. This provides a nearly proportional flow to power ratio at part load.

What is a variable speed screw compressor?

In these applications, screw compressors coupled with VFDs have been utilized to ensure efficient compression at partial and full capacities. Variable speed screw compres-sors allow a wide range of capacity control while maximizing efficiency. WHY COMPROMISE?
