Note :

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 through 15 hp motor Rpm is 1,141 Rpm, maximum 20 hp through 30 hp motor Rpm is 1,170 Rpm.

8. See RT-EB-104 for further details.
