Table 18: Airflow Performance - Bottom Duct Application
JA3ZJ (3.0 Ton) Bottom 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 0.932.
