Exhaust Fan Data
EXHAUST FAN MOTOR SIZING INSTRUCTIONS
In order to determine the proper exhaust fan motor size, add the return duct static pres-
sure to the appropriate damper pressure drop value in
Table 16 on page 53
to get the
total static pressure applied to the exhaust fan. Based on the exhaust fan airflow and total
static pressure, determine the brake horsepower (BHP) and RPM of the exhaust fan.
