The main difference between an air compressor and an air blower is the pressure ratio of each. An air compressor operates at a high pressure to volume ratio, while an air blower tends to operate at a low-pressure ratio.
A compressor crams air into a small space which makes the air denser. A blower moves air/gas with a moderate increase of pressure. The direction of the air being pushed by the blower can be changed by making changes to the blade angle of the blower.
We have both air compressors and blowers here at Atlas Copco that can be used for a wide range of applications. Call us on 1800 023 469 to find out which is more suitable for your production.
