This part changes according to the change of working conditions. If the gas consumption is stable and matches the air compressor's exhaust volume well, then this part has a small loss, otherwise, the loss is large.
If it is a belt-driven screw machine, the belt needs to be replaced.
The burden of the post-processing device of the piston air compressor is heavier, which may increase the maintenance cost of the post-processing device.
Another factor to consider is that after a period of time, the piston air compressor will reduce the exhaust volume due to wear. If the margin is not considered enough when selecting the model, it will cause insufficient gas and affect production efficiency. Sometimes An additional air compressor with a small displacement must be added to make up, which is also an additional expense. And the displacement of the screw air compressor will never drop
