Lau 01556507 Blower Wheel

For contractors requiring a high-capacity replacement, the Lau 01556507 blower wheel (also identified as 150-01556507) is a direct drive blower wheel engineered for heavy-duty HVACR performance. This DD12-12A model features a 12 5/8" diameter and 12 5/8" width, utilizing a double inlet forward curved design to move maximum air volume while maintaining quiet operation. Built with galvanized steel and a concave center disc, it employs Preslok construction to ensure the 53 blades remain securely attached under high-torque conditions. Designed for a 1/2" bore motor shaft, this CW rotation wheel is rated for a 1200 max RPM and is typically used in residential furnaces and commercial air handlers. Precision balancing at the factory helps eliminate vibration, protecting the blower motor from premature bearing wear. This universal replacement wheel is the industry standard for restoring static pressure and airflow efficiency in systems requiring a 12-inch class squirrel cage fan.

• Preslok Center Disc: Mechanically attaches 53 forward curved blades to the center disc for superior structural integrity at 1200 RPM.
• Heavy-Duty Construction: Manufactured from galvanized cold-rolled steel to resist corrosion in moisture-rich air conditioning environments.
• Dynamic Balance: Optimized blade spacing and factory balancing minimize noise and mechanical stress on the HVAC blower motor.
• Universal Compatibility: Standard 1/2" bore and CW rotation make it a direct drop-in for numerous OEM direct drive assemblies.

• How do I confirm the rotation of this wheel? Rotation is determined by looking at the hub/bore end. This unit is Clockwise (CW) rotation.
• What causes a blower wheel to vibrate or shake? Excessive vibration is often caused by dirt buildup, a loose set screw, or a bent shaft. Using a balanced Lau 01556507 ensures a smooth, quiet spin.
• Will this wheel fit a 5/8" motor shaft? No, this specific model requires a 1/2" bore. Verify your motor shaft size using a caliper before installation.
