Lau 02895769 Blower Wheel

The Lau 02895769 Blower Wheel is a high-performance single inlet centrifugal fan wheel engineered for precise air movement in restricted spaces. Designed as the primary direct replacement for S1-8865-3611, this wheel features a 3-13/16" diameter and a 1-7/8" width, making it a critical component for maintaining static pressure in packaged terminal air conditioners (PTAC) and fan coil units. Constructed from heavy-duty galvanized steel, it provides the structural integrity required to handle a 4500 max RPM rating while resisting corrosion in high-moisture environments. The 5/16" bore is standard for most small-diameter motor shafts, though the hub can be field-bored up to 5/8" to clear specialized applications. With its counter-clockwise (CCW) rotation, identified from the backplate side, this direct drive blower wheel ensures optimal efficiency in draft inducers and power burners where airflow consistency is non-negotiable for combustion safety.

Key Benefits

• Universal Compatibility: Serves as a drop-in replacement for part number S1-8865-3611, ensuring zero-clearance issues during emergency repairs.
• Industrial-Grade Build: Standard galvanized steel construction prevents rust and blade deformation under high-velocity stress.
• High-Speed Rating: Rated for 4500 RPM, allowing for use in high-static pressure inducer assemblies and blowers.
• Modular Design: The single inlet design allows for back-to-back mounting if a double-inlet configuration is required for custom HVAC retrofits.
• Field Versatility: Features a 5/16" bore that can be modified to 5/8", accommodating a wider range of motor shaft diameters in the field.

Common Questions

How do I determine the rotation for the Lau 02895769?
Rotation for this single inlet wheel is determined by looking at the backplate (the closed side opposite the inlet). This model is CCW (Counter-Clockwise) rotation.

Can this wheel replace a plastic blower wheel of the same size?
Yes, if the diameter (3-13/16"), width (1-7/8"), and bore (5/16") match, this galvanized steel wheel is a durable upgrade over plastic OEM wheels.

What systems typically use this specific wheel size?
Technicians commonly find this wheel in PTAC units, draft inducers for furnaces, power burners, and small fan coil units across residential and commercial sectors.
