For a pressure loss of 4000 Pa, should a centrifugal fan or a Roots blower be used? !

Are Lohse fans considered constant-flow fans?
Based on the on-site process requirements, select the two types of fans first, and then consider factors such as power, ease of operation, supporting utility systems, and maintenance.
Air volume is very important. For low flow rates, rotary vane blowers are preferred; for high flow rates, centrifugal blowers are better
What level of low flow counts as low?
Write down your flow rate, medium, and resistance – everyone here will help you figure it out!
500CMH, air, final resistance of about 4000Pa.
Oh, that’s not right. It is 2000 CMH, air, with a final resistance of about 4000 Pa.
It’s better to use a centrifugal fan for this; it’s just a very small fan!
