For users with higher energy efficiency requirements, we also offer the Pro+ Series two-stage compression air compressors. The Pro+ Series adopts a horizontal two-stage compression screw airend, paired with an IE5 oil-cooled permanent magnet motor and a variable frequency controller. The double-end isothermal compression enhances compression efficiency while reducing energy consumption, achieving approximately 15% energy savings and complying with national energy-saving certifications. Equipped with an intelligent variable frequency system, the equipment can adjust the motor speed in real time according to the production air demand, reduces the speed during low air demand periods to avoid energy waste.
