Notes:

1.Fan performance for 20 and 25 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: 20 Ton — 9,000, Cfm 25 Ton — 11,000 Cfm.

5.Minimum motor horsepower is 3 hp.

6.Maximum motor horsepower as follows: 20 Ton — 10 hp, 25 Ton — 15 hp.

7.Maximum 3 hp and 5 hp motor Rpm is 1,100, maximum 7.5 hp to 15 hp motor Rpm is 1655.

8.See RT-EB-104 for further details
