Selection of fans

2019-04-18View Original

Thread Content

I would like to ask the experts in the group for help. I’ve recently encountered a problem with selecting fans – I’m not sure how to calculate the air resistance in the ducts, nor how to determine the total pressure required by the fan Is there an approximate calculation formula? Thank you

What is the compression ratio of the fan? What is the maximum negative pressure at the inlet of a centrifugal fan?
