Overall dimensions and technical information are provided solely for informative purposes and may be modified without notice Pressure booster 2 | 226 Series P+ 2 s Procedure 1) Calculate the K' ratio between the initial tank pressure and the inlet booster pressure (P2'/ P1). 2) Calculate the K'' ratio between the final tank pressure and the inlet booster pressure (P2''/ P1). 3) Locate, on the chart illustrating, the booster filling time, the intersection point between the K’ ratio and the curve, then trace a vertical line from the intersection point to the vertical axis and read the correspondent value T’ (in the example chart, to a ratio of 0.8 corresponds a time value of about 3.6 seconds). 4) Repeat the operation for the K’’ ratio, obtaining the T'' time. 5) Use the following formula to obtain the total time needed to take the tank of volume V from the pressure value P2’ to the pressure value P2’. Example of calculation of the necessary time to take a 10L tank from the pressure value P2’ to the value P2” Filling Characteristics (5 litres tank) Filling time (s) K ratio P2/P1 P1 = Inlet pressure P2 = Tank pressure
