First, find the drawdown multiplier by matching the pump start-up and shut-off pressures onChart 2. For example, the multiplier for a 30-50 PSI pressurerange is.

3 , insert the pump GPM capacity and desired minimumrun time into this formula:To assume dependable drawdown volumes, and in keepingwith present industry practice, drawdowns are based onBoyle s Law. For example, using a 10 GPM pump, a oneminute minimum run time, and a 30-50 PSI pressure range,the formula is as follows:Then, using Chart 3, select the tank that has a minimumvolume that meets or exceeds your minimum volumerequirement and supplies adequate drawdown at therequired pressure range. Minimum drawdown equals PumpGPM X Minimum Run Time. Therefore, in the aboveexample, select the PAD-36S 36-gallon tank. It providesadequate drawdown at 30-50 charts below allow you to easily select the rightPerma-Air PAD Series tank for standard-size pumpsbetween 2-1/2 and 30 gallons in capacity and for 20-40 PSI,30-50 PSI and 40-60 PSI pressure ranges.

4 Minimum runtimes shown (from start-up) are 1 minute, 1-1/2 minutes and2 minutes. For example, for a system that delivers 10 GPMat 30-50 PSI, with a minimum run time of 1 minute, Chart 1indicates that the proper tank is the PAD-14 PAD-14 PAD-20 PAD-36 SPAD-36 SPAD-52 PAD-86 PAD-86 PAD-86 PAD-14 PAD-20 PAD-36 SPAD-52 PAD-52 PAD-86 PAD-86 PAD-119(2)PA D -86 PAD-14 PAD-36 SPAD-52 PAD-86 PAD-86 PAD-86 PAD-119(2)PA D -86(2)PA D -86 PAD-14 PAD-20 PAD-36 SPAD-36 SPAD-52 PAD-52 PAD-86 PAD-86 PAD-119 PAD-14 PAD-36 SPAD-36 SPAD-52 PAD-86 PAD-86 PAD-119(2)PA D -86(2)PA D -86 PAD-20 PAD-36 SPAD-52 PAD-86 PAD-86 PAD-119(2)PA D -86(2)PA D -86(2)PA D -119 PAD-14 PAD-20 PAD-36 SPAD-52 PAD-52 PAD-86 PAD-86 PAD-96 PAD-119 PAD-20 PAD-36 SPAD-52 PAD-86 PAD-86 PAD-96 PAD-119(2)PA D -86(2)
