Air compressor data book:

1. Single stage air-cooled air compressor
When the pressure of Single air-cooled air compressor control in 0-0.8MPa, the air displacement in every KW it produce is more than Two-stage air-cooled air compressor. For example, when pressure is up to 0.8MPa, we advice you to use Two-stage air-cooled air compressor.

2. Two-stage air-cooled air compressor
Two-stage air-cooled air compressor's pressure is between 0.7-1.2MPa. Beacuse the compressed air is cooled when it comes to the second compress and the compress is little, using the Single stage air-cooled air compressor will be high efficiency, electrical-saved.
