Note ! Pump Efficiency is the ratio of pump input and output power. This is the motor shaft (output) power. Since the CPR is always greater than 1.0 and the value of gam, the ratio of specific heats, is about 1.4 for air, the total temperature ratio is also greater than 1.0. Using a small amount of compressed air as their power source, Super Air Amplifiers pull in large volumes of surrounding air to produce high volume, high velocity outlet flows through a fixed air gap. Bore: (diameter) Stroke: Cylinder Head Volume: Effective Dome Volume: Use (-) for Dome and (+) for Dish. Filter pressure drop, air usage and leakage, installation pipework and more.
