Notes:
1. Fan performance for 40, 50, and 55 ton rooftops is
identical. However, note maximum motor hp size for
each size. Contact your local Trane representative for
information on oversized motors.
2. Shaded areas at table extremes note non-standard
Bhp or Rpm selection. Contact your local Trane
representative for more information.
3. Supply fan performance table 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
exhaust fan, optional heating system, optional
cooling only extended casing, optional roof curb).
4. Maximum Cfm (for UL approval) as follows:
40 Ton — 18,000 Cfm
50 Ton — 22,500 Cfm
55 Ton — 24,000 Cfm
5. Minimum motor horsepower is 7.5 hp.
6. Maximum motor horsepower as follows:
40 Ton — 30 hp
50 Ton — 30 hp
55 Ton — 30 hp
7. Maximum 7.5 hp to 15 hp motor Rpm is 1,141 Rpm,
maximum 20 hp to 30 hp motor Rpm is 1,170 Rpm.
8. See RT-EB-104 for further details.
