TNITRIB AC Condenser Fan Blade Replacement for Dometic Brisk Air Duo-Therm — Direct-Fit 6-Blade Polymer

TNITRIB 3313107.015 is a direct-fit replacement condenser fan blade designed to restore airflow and quiet operation for Dometic Brisk Air and Duo-Therm RV air conditioners.

This precision-molded fan blade replaces Dometic part numbers 3313107.0150000001, 317937.000, and 3107914.008 to bring your rooftop air conditioner back to effective cooling performance without buying a whole unit. Built to match the original geometry, the TNITRIB blade uses six aerodynamic fins and durable materials to push more air through the condenser while resisting damage from debris. It’s intended for owners of RV, motorhome, and camper units who need an exact-fit replacement that’s affordable and straightforward to install.

How does this replacement blade improve my RV air conditioner’s performance?

Replacing a worn, cracked, or noisy fan blade restores the condenser’s ability to move air efficiently, which helps the unit reach desired temperatures faster and reduces strain on the fan motor. The six-blade design is optimized for steady airflow and balanced rotation.

• Restores original airflow volume and balance for smoother operation
• Reduces vibration and noise compared to damaged or warped blades
• Helps maintain condenser heat transfer efficiency

Will this TNITRIB blade fit my Dometic Brisk Air or Duo-Therm model?

This part is made for Dometic Brisk Air and Duo-Therm rooftop systems and lists compatibility with a wide range of Brisk Air and Heat Pump models. Check your current Dometic part number to confirm a match before ordering to ensure a correct, bolt-on fit.

• Direct replacement for Dometic part numbers 3313107.0150000001, 317937.000, 3107914.008
• Compatible with Brisk Air series models including 532, 546, 548, 557, 558, 559, 570, 578, 579, 589, 590, 595
• Also fits Duo-Therm heat pump models such as 390 and 591

What materials and durability features does this fan blade offer?

The TNITRIB blade is fabricated from reinforced polymer engineered to survive the impact and fatigue stresses common on rooftop units. Its construction resists cracking and warping even when exposed to road debris or high-speed rotation.

• Robust polymer composition minimizes breakage from foreign-object impacts
• Precision molding preserves original blade profile for proper balance
• Corrosion-resistant material suitable for outdoor RV conditions

How difficult is installation and what should I check before replacing the blade?

Installation is typically straightforward for someone comfortable with basic hand tools—remove the top cover, unbolt the old blade from the motor shaft, and mount the TNITRIB replacement in the same orientation. Verify shaft size and secure fasteners to factory torque to maintain balance.

• Requires basic tools: screwdriver, socket set, and thread locker if desired
• Confirm motor shaft diameter and blade orientation before tightening
• Inspect motor bearings and electrical connections while unit is open
