AUTO-DRAFT® VENTER FAN PERFORMANCE CURVES
Auto-Draft® Venter performance was independently tested by an accredited AMCA certified testing facility.
Selection of an Auto-Draft® Venter involves determination of the maximum volume of gas to be handled, the density of the gas and
the maximum static pressure which the fan must overcome.
Variable speed VSAD-Series Venters can operate at virtually any point to the left of the performance curve. For Side Wall applica-
tions add 0.50” W.C. to vent system resistance to accommodate the effects of wind loading.
Auto-Draft® Venter performance needs to be derated from 70
O
F performance curves to anticipated flue gas temperatures.
