Lau 38251301M Blower Assembly
The Lau 38251301M (Model DD9-7A) is a contractor-grade direct drive blower assembly engineered for drop-in compatibility in residential furnaces and light commercial air handlers. This assembly features a 9-3/16-inch by 10-1/4-inch double inlet blower wheel housed in a heavy-gauge G90 galvanized steel housing, ensuring structural integrity during high-static operation. Built with a 1/2-inch bore for CW (clockwise) rotation, it integrates seamlessly with standard direct drive motors. The unit utilizes Lau’s precision-balancing technology to minimize shaft vibration and bearing wear, which is critical for maintaining CFM output in ducted systems. To streamline installation, the assembly includes a universal motor mounting bracket and pre-installed Vibro-Pads for acoustic isolation. This HVAC blower replacement is the industry standard for technicians requiring a reliable, centrifugal fan assembly that meets tight tolerance specifications for air movement and heat exchange efficiency.
Key Benefits for Contractors
- Universal Mounting Flexibility: Equipped with adjustable motor brackets and universal housing supports to accommodate various furnace duct configurations.
- Superior Vibration Dampening: Integrated Vibro-Pads reduce mechanical resonance and noise transfer through the ductwork.
- High-Efficiency Airflow: The precision-balanced blower wheel ensures consistent static pressure performance and reduces the load on the motor.
- Industrial Build Quality: Heavy-gauge galvanized steel construction prevents corrosion and housing flex in high-humidity environments.
Common Questions
Is this blower assembly compatible with different motor speeds?
Yes, as a direct drive configuration, the Lau 38251301M is designed to work with multi-speed motors, provided the motor horsepower and RPM ratings match your system's static pressure requirements.
Does this unit include the blower wheel and housing?
This is a complete blower deck assembly, featuring the centrifugal wheel, the galvanized housing, and the necessary mounting hardware for the motor.
How do I verify the rotation for my application?
This model is configured for Clockwise (CW) rotation when viewing the unit from the motor/shaft side. Always verify your existing blower's orientation to ensure proper airflow direction.
