Rotary screw air compressors can either be belt drive or direct air compressors. The belt drive air compressors have a belt that connects the motor to the crankshaft. In the direct drive air compressor, the motor is attached directly to the crankshaft. As such, this type air compressor is fast and powerful.
The direct air compressors are less adjustable than the belt drive compressors. However, due to the direct connection they are more efficient and power loss through transmission is minimized. The direct drive air compressors have fewer moving parts than the belt drive. Consequently, this means there are fewer parts that can wear out or get damage stalling operations.
Direct air compressors are ideal for use in heavy commercial or industrial applications where the belt drive air compressors cannot be efficient. Direct air compressors require more upfront payment than belt drive air compressors. However, it becomes easy to recoup this investment because they use less fuel and deliver lots of power. They also require little maintenance therefore you save on those expenses.
The choice between a direct drive air compressor and a belt drive really rests on how you intend to use the compressor. For heavy uses a direct drive air compressor will do fine.
