Notes:
1. Fan performance for 60, 70 and 75 ton rooftops are identical. Contact your local Trane representative for information on non-standard 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: 60 Ton — 27,000 Cfm, 70 & 75 Ton — 30,000 Cfm
5. Minimum motor horsepower is 10 hp.
6. Maximum motor horsepower is 40 hp.
7. Maximum motor Rpm is 1,130.
8. See RT-EB-104 for further details.
