BLOWER PERFORMANCE SPECIFICATIONS

Rev. 2
SINGLE STAGE
1. Units are shipped without filter(s). CFM in chart is without filter(s).
2. All furnaces shipped as high speed for cooling. Installer should adjust blower speeds as needed.
3. INSTALLATION IS TO BE ADJUSTED TO OBTAIN TEMPERATURE RISE WITHIN THE RANGE SPECIFIED ON THE
RATING PLATE.
4. The chart is for information only. For satisfactory operation, external static pressure not to exceed value shown on
rating plate. The shaded area indicates ranges in excess of maximum external static pressure allowed when heating.
5. The above chart is for U.S. furnaces installed at 0-2000 feet. At higher altitudes, a properly derated unit will have
approximately the same temperature rise at a particular CFM, while the ESP at that CFM will be lower.
Note: The models listed in the above airflow table use 10x8 blower assembly instead of 10x6 to achieve a full 4 tons of airflow. Listed below are
the model numbers along with the manufacturing numbers of the five units using the 10x8 blower assembly.
