Ordering Information | Hot Air Blowers
2600 Blowers are designated as follows: 26 - / - /
Horsepower of motor furnished. Horsepower of standard cold air blower (to determine proper impeller).
Frame number/stages Cold air blower pressure in osi. 2600 Blower series.
The horsepower of the motor furnished is the maximum available. This horsepower may decrease with the actual number of pounds being utilized.

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 (316 °C) 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.
