Williams 2907 Blower Assembly

The Williams 2907 Blower Assembly is a high-performance, 125 CFM deluxe accessory engineered specifically for Monterey Plus Top Vent Gas Furnaces. This unit is designed to maximize thermal efficiency by forcing warm air circulation, effectively eliminating cold spots and reducing temperature stratification in large rooms. Built with a centrifugal squirrel cage fan, the motor provides powerful yet quiet airflow compared to standard axial blades. It is compatible with Monterey series 25098, 35098, and 50098 models, and is essential for the 50,000 BTU double-sided units which often require dual blowers for optimal heat distribution. The assembly includes a three-prong power cord and a thermostatically controlled fan switch with three settings: AUTO (thermal activation), ON (constant circulation), and OFF. This 115V field-installed kit features a soft-white finished grille to match the furnace cabinet and requires a standard outlet adjacent to the unit for operation.

Key Benefits:

• 125 CFM Airflow: High-capacity blower increases the heat throw and volume of warm air forced into the living space.
• Automatic Fan Switch: Features a heat sensor switch that activates the motor only when the plenum reaches operating temperature, preventing cold drafts.
• Squirrel Cage Design: The centrifugal fan blade ensures higher static pressure and quieter operation for residential applications.
• Multi-Model Compatibility: Verified for use with Williams 25098XX, 35098XX, and 50098XX furnace series.
• Dual-Blower Ready: Specifically designed for 50,000 BTU models that utilize two 2907 units for front and rear heat distribution.

Common Questions:

Does this blower run constantly or only when the heat is on?
When set to the AUTO position, the integrated fan/heat sensor switch automatically triggers the motor only after the furnace heat exchanger has warmed up. For continuous air filtration or circulation, you can manually toggle the switch to the ON position.

What electrical requirements are needed for installation?
The assembly is rated for 115V AC and draws less than 3 amps. A grounded electrical outlet must be installed within reach of the provided power supply cord. Ensure all wiring conforms to NFPA 70/ANSI National Electrical Code.

Will this work with Monterey 2901 series furnaces?
The 2907 is the high-flow 125 CFM deluxe version. While it shares mounting footprints with the 2901, it is the preferred replacement for contractors requiring maximum air movement in Top Vent Monterey Plus configurations.
