The recommended air requirement for the operation of APT tools is 90 psi (6.2 bar). Lower air pressure will decrease power, too high a pressure will increase unwanted stresses in the tool. For proper CFM ratings, please refer to the specification charts shown for each tool in this catalog.
APT recommends the use of at least 1⁄2” inside diameter or larger hoses to assure sufficient air flow to the tool. For portable compressor hose and longer lengths, 3⁄4 “ hose is recommended. Keep the overall length of the hose to a minimum to prevent pressure loss at the tool.
Hoses should be rated for a minimum of 250 psi (17.2 bar). Before connecting the air hose to the tool, check the tool inlet connector to be sure it is clean and free of dirt or debris. Keeping dirt and debris from entering the tool will assure long and satisfactory operation.
