Lennox 81G49 Motor

For mid-static pressure applications requiring precise airflow management, the Lennox 81G49 Blower Motor is a high-performance 1/5 HP HVAC replacement motor engineered for single-phase 208-230V systems. This PSC (Permanent Split Capacitor) drive operates at a nominal 825 RPM and features a 3-speed configuration, allowing technicians to fine-tune CFM delivery to meet specific cooling or heating loads. Built with a rugged 48Y frame and a 1/2-inch by 2.5-inch single-side flat shaft, this OEM blower motor ensures drop-in compatibility with Lennox CB19 and CBH19 series air handlers. The motor is thermally protected and utilizes self-aligning ball bearings for extended service life in direct drive blower assemblies. When replacing the 81G49, always verify the 5 MFD @ 370 VAC capacitor and inspect the blower wheel for balance to prevent premature bearing wear caused by vibration.

• Multi-Speed Versatility: Three distinct speed taps provide flexible airflow control for various duct static pressures.
• High-Efficiency PSC Design: Permanent Split Capacitor technology reduces energy draw compared to standard shaded-pole motors.
• Industrial Build Quality: Features a resilient steel frame and aluminum flange for superior heat dissipation in continuous air-over applications.
• Direct OEM Fit: Specifically engineered to replace 81G4901 and K55HXJRT-3026 models without bracket modification.

What air handler models are compatible with this motor?
The Lennox 81G49 is designed for use in Lennox, Armstrong, and Allied units, specifically fitting CB19-26 and CBH19-26 series blower decks.

Does this motor require a specific capacitor for startup?
Yes, this 825 RPM blower motor requires a 5 MFD at 370 VAC run capacitor. Using an incorrectly rated capacitor can lead to motor overheating or failure to start under load.

Can the rotation of the 81G49 be reversed in the field?
While many PSC motors are reversible, this model is typically factory-set for CCW Lead End (CCWLE) rotation. Always verify the rotation matches your existing blower wheel before final installation.
