How will this blower wheel affect my RV’s airflow and performance?

Restoring a worn or damaged blower wheel brings the fan back to its intended airflow and balance, which helps the rooftop unit move air efficiently. While it replaces the mechanical fan only, a balanced, properly sized wheel supports smoother operation and reduces strain on the motor.

• Squirrel-cage design for consistent, directed airflow
• Correct diameter and width to maintain rated airflow volume
• Balanced construction to minimize vibration and noise
• Helps prevent premature motor wear from imbalanced fans

How difficult is installation and what tools are required?

Installation is straightforward for someone with basic RV repair experience: remove the access panel, detach the old wheel, and slide the replacement onto the motor shaft. The Pellethead unit is built for secure mounting and aligns with the original retention method used in Duo-Therm housings.

• Typical tools: screwdriver set, pliers, socket wrench, and retaining-ring tool if applicable
• No permanent modifications required — direct-fit design
• Approximate install time: 30–60 minutes for experienced DIYers
• Inspect shaft key/retaining hardware and replace if worn

What are the construction and durability features of this replacement wheel?

The blower wheel uses a robust squirrel-cage frame sized to OEM dimensions, produced to resist deformation and keep blades aligned under operating load. The materials and balance help maintain consistent performance over many seasons of RV use.

• Sturdy cage profile to resist bending and blade fatigue
• Precision bore for snug 1/2" shaft fit and reduced wobble
• Approximately 2.9" width to match original clearance and airflow path
• Manufactured as an aftermarket OEM-equivalent replacement
