Profile: Kaishan USA is an industrial air compressor manufacturer who produces compressed air equipment for a variety of industries. We manufacture rotary screw air compressors, vacuum pumps, portable air compressors, ORC power expanders, steam screw expanders and air treatment equipment to take care of all of compressed air needs. Direct drive air compressors are part of extensive line of air compressor products ? intended for applications where durability, efficiency and reliability are key. Direct driven air compressors are a type of rotary screw air compressor and are typically compared with belt driven compressors when choosing the right equipment for an application. In a direct drive air compressor, the motor is connected directly to the compressor, transferring power right from the motor to the pump. In contrast to a belt driven air compressor, where a belt facilitates the transfer of power, a direct driven air compressor operates more efficiently, with no power lost in the transition from the motor to the belt to the pump. In addition, a direct drive compressor has fewer moving parts and, thus, is less subject to failure, while incurring reduced wear and tear.
