Important:
• Relief fan performance curve includes internal resistance of rooftop. For total static pressure determination, add
together return ESP and relief damper pressure drop.
• Static pressure drops from the space to the relief fan (relief damper + return ESP) cannot exceed 3.5 in w.c.
• Curve can show combined operating min/max for multiple tonnages. Refer to general data for appropriate
operating parameters such as motor horsepower and airflow ranges.
• Shaded areas represent unavailable selections. Contact your local Trane® representative for more information
on selections in these shaded regions.
• EC motors are not offered in integral horsepower increments. Fans will be offered with a nominal motor power
rated to cover the operating envelope of the fan. Power limitation is indicated by the highest power shown on
the curve.
• Max RPM is indicated on curve and RPM values are in increments of 200 RPM unless otherwise shown.
• Catalog curves represent fan data corrected to the following standard conditions: 70°F dry bulb temperature,
barometric pressure of 14.696 psia, and an air density of 0.075 lb/ft
fan curves for unit-specific operating temperatures and elevations.
