The fan coils in the VED series have been designed to make it possible to adjust the static pressure supplied by the fan upon pres-
sure drops in the duct by choosing an appropriate set of three speeds.
The graph shows the useful static pressure of the machines with the uprated multispeed motor in function of the air flow rate and
speed of the fan (V1...V5).
