• Shaded areas represent selectable area.
Contact your local Trane ® representative for

• 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: 20 ton - 9,000 Cfm, 25 ton - 11,000
Cfm.
• Minimum motor horsepower is 3 hp.
Maximum motor horsepower is 20 hp.
Maximum fan RPM is 2400.
