VENTILATION CURVES
The following diagrams show the ow rate-useful static pressure curves (at vent) of the units, with 4-row coil and with a 0% clogging degree of
the G4 lter.
For units with dierent congurations or accessories, reduce the useful static pressure with the pressure drop values of the added components. The
values of these pressure drops can be found on the tables below the charts.
