Notes:
• Shaded areas represent selectable area.
Contact your local Trane® representative for
more information.
• Supply fan performance curve includes internal
resistance of rooftop. For total static pressure
determination, system external static must be
added to appropriate component static
pressure drops (evaporator coil, filters, optional
economizer, optional relief fan, optional heating
system, optional cooling only extended casing,
optional roof curb).
• Maximum Cfm (for cULus approval) as follows:
30 ton - 13,500 Cfm.
• Minimum motor horsepower is 5 hp. Maximum
motor horsepower is 20 hp. Maximum fan RPM
is 1450.
