• Shaded areas represent selectable area.
Contact your local Trane
® representative for
more information.
• 70-75 ton gas heat units use 30" DDP fans.
See
Figure 58, p. 89 .
• 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: 60 ton gas heat and 70, 75 tons -
27,000 Cfm.
• Minimum motor horsepower is 10 hp (2 x 5
hp motors). Maximum motor horsepower is
50 hp (2 x 25 hp motors). Maximum fan RPM
is 2,000.
