TABLE 20 – 50 THROUGH 65 TON EXHAUST FAN DATA
EXHAUST FAN MOTOR SIZING INSTRUCTIONS
In order to determine the proper exhaust fan motor size,
add the return duct static pressure to the appropriate
damper pressure drop value in Table 23 to get the total
static pressure applied to the exhaust fan. Based on
the exhaust fan air flow and total static pressure, deter-
mine the brake horsepower and RPM of the exhaust
fan.
