The core of oil-free screw air compressor is outstanding two-stage compressor. After 20 processes of finishing, the rotor line shape achieves unparalleled accuracy and durability. High quality bearings and precision gears are installed inside to ensure the coaxiality of the rotor and make the rotor fit accurately, so as to maintain long-term, efficient and reliable operation.
无油螺杆空压机是属于微型往复式活塞式压缩机，电机单轴驱动对称分布曲柄摇杆机械结构，主运动付为活塞环，副运动付为铝合金圆柱面，运动付之间同活塞环自润滑而不添加任何润滑剂。
The oil-free screw air compressor belongs to the micro reciprocating piston compressor. The motor drives the mechanical structure of the crank rocker symmetrically. The main movement pair is the piston ring, and the auxiliary movement pair is the aluminum alloy cylindrical surface. The movement pair is self-lubricating with the piston ring without adding any lubricant
