Lau DD10-10A Double Inlet Blower Wheel 10.625x10.625 in

Product Description

The LAU DD10-10A is a double inlet, direct drive blower wheel designed for use in forced-air HVAC systems where balanced airflow and quiet operation are required. Built from galvanized steel, this forward-curved wheel measures 10.625 inches in diameter by 10.625 inches in width and accepts a 1/2-inch bore shaft. It features a 48-blade configuration with a maximum rated speed of 1750 RPM. The Preslok center disc uses a specialized hub engineered specifically for direct drive blower applications. HVAC technicians and mechanical contractors install this wheel as a universal replacement in residential and light commercial blower assemblies.

This blower wheel fits double inlet blower housings in the 9-inch to 11-inch diameter range, making it a versatile replacement across a wide range of forced-air heating, cooling, and ventilation equipment. Precise blade spacing and consistent alignment contribute to stable airflow and reduced vibration during operation. It is appropriate for residential furnaces, air handlers, and similar ducted HVAC equipment where a direct drive, double inlet wheel is specified.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out all electrical power to the air handler or furnace before removing the existing blower wheel. Verify shaft diameter and rotation direction match the application before mounting. Ensure the set screw engages the flat on the motor shaft and that the wheel spins freely without contacting the housing before restoring power.
