CLLOMAGY RV Condenser Fan Blade for Dometic Brisk Air 10.5" x 3" D‑1/2" Shaft — Direct Fit, Quiet Efficient Airflow

CLLOMAGY 3313107.015 is a direct-fit RV condenser fan blade designed to replace Dometic Brisk Air/Duo-Therm units (OEM 3107914.008) and restore quiet, efficient airflow.

If your RV or travel trailer air conditioner is noisy, vibrating, or not moving enough air, a worn or broken condenser fan blade is often the culprit. This CLLOMAGY replacement matches the original D-shaped 1/2" shaft interface and the original 10-1/2" diameter x 3" thickness to fit Brisk Air heat pump and AC series models. It’s a cost-effective way to get your cooling or heat-pump condenser moving properly again without replacing the entire head unit.

How does installing this blade improve RV AC performance?

A properly sized condenser blade promotes steady airflow across the condenser coil, which helps heat exchange and reduces noise from imbalance or blade damage. Replacing a cracked or unbalanced blade reduces vibration and can relieve strain on the motor and bearings.

• Restores balanced airflow to improve condenser efficiency and cooling performance.
• Reduces vibration and operating noise for quieter trips and campsites.
• Limits extra wear on the motor by replacing imbalanced or damaged paddles.

What are the key physical specs and installation tips?

Knowing dimensions and mounting orientation prevents fitment mistakes. This blade uses the same D-shaped 1/2" bore and overall size as the original so it mounts directly to compatible Dometic motors when oriented correctly.

• Dimensions: 10-1/2" diameter × 3" thick; shaft hole: D-shaped 1/2".
• Mounting note: the side with the screw holes faces the motor—confirm orientation before tightening.
• Watch installation videos or consult guides if unsure; double-check model fit before ordering.

Can I replace the fan blade myself, and what should I watch for?

Many RV owners handle this swap with basic tools, but attention to safety and proper alignment is essential. Follow manufacturer guidance and ensure power to the unit is fully disconnected before starting.

• Turn off shore power and battery connections before disassembly.
• Inspect motor shaft, set screws, and fan shroud for damage while replacing the blade.
• Confirm blade orientation and torque set screws per motor spec to avoid slippage.

Who this is for: This CLLOMAGY 3313107.015 fan blade is intended for RV owners, technicians, and DIYers who need a reliable, OEM-compatible replacement for Dometic Brisk Air and Duo-Therm systems.
