• Direct-fit geometry for Dometic 3310709.005 replacements
• Matches original mounting and blade count (six blades)
• Works with standard rooftop AC fan motors used in many RV models
• Basic hand tools required for replacement

How quiet and efficient is this replacement compared with the original?

The six-blade design optimizes airflow through the condenser while minimizing turbulence that creates noise. Balanced blades and sturdy construction help the fan turn smoothly at operating speed, reducing vibration and audible hum when correctly installed.

• Six blades for steady, high-volume airflow
• Precision molding reduces imbalance and vibration
• Durable material resists chip or crack from debris strikes
• Can help restore original noise and cooling performance

What materials and durability can I expect from TNITRIB parts?

TNITRIB manufactures this fan blade from reinforced plastic engineered to withstand the centrifugal forces of AC operation and occasional impacts from foreign objects. The material choice balances light weight with toughness so the blade resists breakage and maintains shape under heat and rotation.

• Reinforced polymer construction for impact resistance
• Stable at typical rooftop AC operating temperatures
• Less prone to cracking than cheap, brittle alternatives
• Quality inspected to meet or exceed original specifications

Can replacing just the fan blade fix cooling issues, or do I need a full motor swap?

Replacing a damaged or unbalanced blade often resolves airflow loss and noise problems without replacing the motor. However, if the motor shows signs of failure — such as seizing, excessive wobble, or electrical faults — a motor repair or replacement may be necessary in addition to the blade.

• Blade swap solves physical damage and imbalance issues
• Check motor for smooth rotation and no abnormal sound
• Inspect shaft and mounting hardware for wear before install
• Contact TNITRIB support if unsure about compatibility or symptoms

Who is this for: This TNITRIB fan blade is aimed at RV owners, technicians, and DIYers who need a dependable, cost-effective replacement for a Dometic 3310709.005 condenser fan blade. It suits anyone wanting to restore condenser airflow and reduce noise without replacing the entire rooftop unit, and it’s a practical part for maintenance shops stocking common Dometic replacement components.
