Lau 02694007 Blower Wheel
The Lau 02694007 Blower Wheel is a high-performance direct drive blower wheel engineered for residential and light commercial HVAC applications. Also classified as Model DD11-8A, this double inlet blower wheel features a 11 3/4" diameter and 8" width, making it a critical component for maintaining optimal static pressure in air handlers and furnaces. Built with 53 forward-curved blades and a Preslok center disc, the unit ensures positive blade retention and balanced rotation at speeds up to 1550 max RPM. The 1/2" bore and clockwise (CW) rotation are designed for a seamless fit with standard HVAC blower motors, specifically those utilized in direct drive configurations. Fabricated from heavy-gauge galvanized steel, this squirrel cage fan provides superior resistance to corrosion and mechanical stress. Whether you are performing a Lau blower wheel replacement or upgrading a forced-air system, this convex, high-capacity wheel delivers the low-noise, high-velocity airflow required by modern climate control systems.
Key Benefits
- Preslok Center Disc Construction: Features 53 blades mechanically locked into the center disc for high-speed stability and vibration reduction.
- Galvanized Steel Build: The cold-rolled galvanized steel construction prevents oxidation and extends the life of the wheel in high-humidity environments.
- Dynamically Balanced: Factory balancing reduces bearing wear on the blower motor and minimizes operational noise.
- Direct Drive Efficiency: Specifically designed for direct drive blower wheel systems, ensuring maximum torque transfer and efficiency.
Common Questions
How do I confirm the rotation of my existing blower wheel?
To determine the correct rotation, view the blower wheel from the bore (hub) end. The Lau 02694007 is a CW (clockwise) rotation model. If your motor requires CCW rotation, this part will not move air correctly.
Does this wheel fit 5/8" motor shafts?
No, this specific model features a 1/2" bore. Attempting to modify the hub for a larger shaft can compromise the balance and dynamic integrity of the wheel.
Can this be used in belt-drive applications?
This is an 11-8A series wheel designed specifically for direct drive setups. While dimensions may look similar to belt-drive wheels, the hub configuration and RPM rating are optimized for direct-coupled motors.
