Table 15: Air Flow Performance - Side Duct Application

J15ZJ (15 Ton) Side Duct

Air Flow

(CFM)

Available External Static Pressure - IWG

1. Blower performance includes gas heat exchangers and 2” filters. See STATIC RESISTANCE table for additional applications.
2. See RPM SELECTION table to determine desired motor sheave setting and to determine the maximum continuous BHP.
3. kW = BHP x 0.898.
