Selection guide for air compressor

Selection of working pressure (exhaust pressure): When the user is preparing to purchase an air compressor, first determine the working pressure required by the air end, add a margin of 1-2 bar, and then select the pressure of the air compressor (the margin is considered from the air compressor The pressure loss from the installation site to the actual gas end pipeline distance, according to the length of the distance between 1-2 bar, appropriately consider the pressure margin)
