WSRXG RV Air Conditioner 8" Blower Wheel - Plastic Impeller with Reinforced Aluminum Core, 1/2" Bore

WSRXG's upgraded 8" blower wheel is a drop-in replacement for RV and camper AC units, combining a lightweight plastic impeller with a reinforced 6063-T5 aluminum core for reliable, low-vibration airflow.

This blower wheel (compatible part numbers 3313107, 3313107033, 3104887.009, 385002300) is engineered for RV and camper air conditioners where space, weight, and durability matter. The design pairs an abrasion-resistant plastic body with a CNC-machined aluminum center to reduce overall mass while improving heat dispersion and structural stability. Pre-drilled mounting holes and included fasteners make installation straightforward for DIYers and technicians alike.

How durable is the WSRXG blower wheel under outdoor RV conditions?

The unit uses a 6063-T5 anodized aluminum core that resists corrosion, chemical exposure, and UV damage—traits important for rooftop and exposed compartments. The plastic impeller body resists dents and maintains blade geometry under typical vibration and thermal cycles. Together these materials extend service life compared with plain plastic or untreated metal cores.

• 6063-T5 aluminum core, CNC-machined for precision and strength
• Anodized surface finish resists corrosion and UV fading
• Plastic impeller formulated to resist abrasion and deformation
• Balanced assembly to minimize vibration and wear

Will this blower wheel fit my RV air conditioner and how easy is installation?

The blower wheel is sized at 8 inches in diameter with a width of approximately 2.9 inches and a 1/2" shaft bore, matching common RV AC OEM specs. It arrives with pre-installed mounting holes and M4 screws plus a magnetic hex key, so alignment and fastening take only minutes for most models. Check your original part numbers for compatibility or measure shaft and housing clearance before ordering.

• 8" diameter, ~2.9" width, 1/2" shaft bore for common RV units
• Pre-drilled mounting holes that align with OEM patterns
• Includes M4 screws and magnetic hex key for tool-free servicing
• Step-by-step detach, rinse, air-dry, and reinstall maintenance

How does the reinforced aluminum core improve performance?

The aluminum hub is roughly 30% lighter than comparable steel cores, helping reduce rotating mass so the motor works less to spin the fan. Improved heat dissipation prevents localized overheating at the hub, which is beneficial in rooftop units exposed to sun and high ambient temperatures. The rigid metal core also keeps the impeller true, reducing wobble and bearing strain.

• 30% lighter than steel cores lowers rotating inertia
• 2x heat dissipation efficiency protects motor and hub area
• Rigid hub improves balance and reduces bearing loads
• Anodized finish prevents corrosion that can unbalance the wheel

What maintenance does this blower wheel require?

Maintenance is straightforward: remove the wheel in about three minutes, rinse with water, use a neutral detergent only if needed for grease removal, and air-dry before reassembly. The plastic body and anodized core are compatible with routine cleaning agents used for HVAC upkeep. Regular inspection for chips or excessive play in the shaft bore helps prevent failure.

• Quick-detach design for fast cleaning and inspection
• Compatible with neutral detergents for degreasing
• Air-dry only—no harsh solvents required
• Periodic checks of shaft fit and mounting hardware recommended

Who is this for: RV owners, mobile-home technicians, and DIYers looking for a robust, lightweight replacement blower wheel that matches common OEM part numbers (3313107033, 3313107.033, 3104887.009, 385002300). It’s well suited for rooftop air conditioners on campervans and motorhomes where reduced vibration, improved heat handling, and simple installation matter. If you need a direct-fit, serviceable fan wheel that balances performance and longevity, this WSRXG upgrade is built to meet those needs.
