My Roots blower has an air volume of 14.9 m3/min and an air pressure of 7 m; which model of inverter would be suitable for it? Why?

Why is a frequency converter needed for rotary vane blowers? Does the flow rate change frequently?
Reply #32015-07-13
The frequency converter is selected based on the motor, not on the air volume and pressure of the Roots blower. It’s best to go and ask in the electronics section
