Criteria for distinguishing blowers from compressors
Thread Content
I would like to ask the experts: How can one distinguish between a blower and a compressor? Is it by the compression ratio?
Yes, blowers and compressors can usually be distinguished by their compression ratio. The compression ratio of blowers is usually less than 1.3, whereas that of compressors is greater than 1.3. .
Thank you! Jing asked, what is the basis for a compression ratio of 1.3?
**The standards stipulate that: 1) Machinery with a pressure increase of less than 30 kPĎ is referred to as a ventilator. 2) Machinery with an outlet gauge pressure between 30 kPĎ and 0.2 üPĎ is called a blower. 3) Machinery whose outlet gauge pressure is greater than 0.2üPĎ is called a compressor.
I’m sorry, there’s an issue with the unit display.
I’ve learned that the discharge pressure is a more intuitive indicator than the compression ratio. Could fans also be further classified into high-pressure fans, medium-pressure fans, and low-pressure fans? I would appreciate further guidance from experts.
