Selection example: For air flow of 9,000 m3/h and Static pressure (Pa) 200 Pa Transfer the desired air flow rate (m3/h x 1,000) to the flow rate scale Transfer the static pressure value (Pa) to the pressure scale. The intersection of the flow rate and pressure lines produces a point X. This point X provides the following information: The turbine rotation speed - 790 rpm in our example The sound pressure - 55 dB in our example The power input - 2.0 kW in our example To define the motor power required for your installation, select a motor with a power reserve of 10 to 20%.
Static pressure : pressure level in dB(A) measured at 5 m in a room with average reverberation. Intake and discharge outlets connected. Precision ±3 dB(A). To obtain the power level, add 15 dB to the values written on the curves.
