Answer: The pressure drop of the air pipe should not exceed 5% of the nominal exhaust pressure of the air compressor, so it is best to use a larger pipe diameter for the compressed air pipe, the pipe should have fewer turns, and the number of valves should be minimized. The main pipe should have a slope of 1°-2° to facilitate the discharge of condensed water in the pipe (the pipe should have a drainage screw plug). When several compressor units share the compressed air main pipeline, a check valve should be installed between each compressor unit and the main pipeline.
If there are gas storage tanks, dryers and other devices, the air compressor unit should be connected to the gas storage tank first and then to the dryer.
