Blower Performance tables
This equipment is outfitted with a belt driven blower assembly in order to accommodate a large variety of duct
configurations and airflow selections. The blower has been factory inspected for proper alignment, operation and
rotational direction prior to the drive motor being situated in the shipping position. The blower drive belt is located
with these instructions and must be installed by the service technician. For a more detailed explanation of belt driven
blower drives and the operation of their components please refer to any of the installation instructions listed below
for the high static drive kits.
The factory standard drive installed in these units has been set to deliver 400 Cfm/ton at an External Static Pressure
(ESP) of 0.25-0.30 in-Wg. Tables 5-8 show the full blower curves of these drive configurations and can be utilized
to easily set the adjustable motor sheave for alternate configurations. Refer to the Legend below for a description
of the table information. Once a sheave setting has been made, always inspect the blower amp draw to ensure that
it is less then the service factor amps listed on the motor. For systems that include a large number of accessories
or have very restrictive duct systems, alternate drive kits are available – refer to table 4 below for the applicable
kits. The full blower curves for the HSD kits can be found in the applicable kit installation instructions or in the unit
technical service literature.
