Rotary oil injected screw compressor manufacturer for chemical

Direct Driven Screw Air Compressor

Constant Speed & Variable Speed Drives (VSD)

22-630KW  30-850HP

1.Product Profiles

The direct driven screw air compressor transmits electric power to the airend through a flexible coupling, it consumes 

almost no energy in the transmit process, so that direct driven is the most efficient transmission mode.

2.Advantage

(1).There is no intermediate drive, so there is no energy loss.

(2).Larger rotors operate at lower speeds, so it is more efficient and further reducing energy consumption.

(3).It avoids some shortcomings of belt driven air compressor, such as unbalanced force, easy to generate 

heat, the belt is easy to break, frequent belt change, and need to re-adjust the level of the pulley and the 

tension of the belt frequently.

(4).Due to the coaxial transmission of the flexible coupling, the force is balanced and the vibration is 

reduced, which increases the reliability and reduces the maintenance cost.
