2018-Present

Upgrade of the third generation two-stage compression screw air-end and motor

(Adopting horizontal dual-motor structure: it has all the advantages of vertical dual-motor, and compared with vertical twin-motor, horizontal dual-motor air-end has lower center of gravity and less vibration, so it operates more smoothly and reliably)

2015-2017

Upgrade of the second generation two-stage compression screw air-end and motor

(Vertical dual-motor structure: coaxial one-piece structure with 100% transmission efficiency, one and two rotational speeds can be independently controlled to match the optimal rotational speed and give full play to the best performance of the air-end and motor)

2014

The first generation of two-stage compression screw air-end and motor on the market

(Vertical gear structure: lower pressure ratio per stage, reduce internal and external leakage, improve volumetric and adiabatic efficiency as well as energy efficiency of compressor)
