Determining the most appropriate motor is discussed at length in North American’s COMBUSTION HANDBOOK; or a North American engineer can work with you to consider the entire combustion system as well as the blower.
Other blowers can be furnished for 600°F air, using modifications similar to those listed above. On applications where blower is protected against cold air overload or seldom handles cold air, e.g., TwinBed II™ fired continuous furnace exhaust fans, the "hot" horsepower requirement is less than the cold air standard and a smaller motor can be specified.
For coupled, V-belt drive, or blowers not listed, consult Fives North American Combustion, Inc., Cleveland.
