Notes:
1. Fan performance table includes internal resistances of cabinet, and 2” standard filters. For other components refer to component static pressure drop table. Add the
pressure drops from any additional components to the duct (external) static pressure, enter the table, and select motor bhp.
2. The pressure drop from the supply fan to the space cannot exceed 2.25”.
3. Maximum air flow for 27½ ton — 12,100 cfm, 30 ton — 13,200 cfm, 35 ton — 14,400 cfm.
4. Maximum motor horsepower for 27½ ton — 10 hp, 30 ton — 10 hp, 35 ton — 15 hp.
