HLTIT RV AC Condenser Fan Blade Replacement 10.5" Dia x 3" Thick for Dometic Duo‑Therm Brisk II & Penguin — Balanced, Impact‑Resis

HLTIT 3310709.005 is a direct-fit replacement condenser fan blade designed to restore proper airflow and quiet operation in Dometic Duo-Therm Brisk II and Penguin RV air conditioners.

When an RV roof air conditioning unit develops a cracked or unbalanced condenser fan blade, cooling efficiency drops and vibration or noise increases. This HLTIT replacement blade matches the original geometry and mounting profile of common Dometic parts so you can repair the condenser without replacing the whole unit. Built from impact-resistant engineering plastic and balanced at the factory, it aims to return stable, reliable performance quickly and affordably.

Will this fan blade fit my Dometic Brisk II or Penguin AC?

Yes — the 3310709.005 is manufactured to the same size and shaft interface used by many Duo-Therm Brisk II and Penguin condensers. It is intended as a direct substitute for several Dometic part numbers, so compatibility is broad for affected units.

• Matches the 10.5" diameter and 3" thickness of the original blade.
• Uses a 1/2" D-shaped shaft hole for a secure mechanical fit.
• Compatible with series and cross-reference numbers such as 3313107.015 and 3107914.008.
• Works with Dometic cross-references including B57915, B59146, B59186, B59196, B59516, B59530.

How durable and quiet is this replacement blade?

This fan blade is molded from a high-hardness engineering plastic selected to resist impact, deformation and the stresses of high-RPM operation. Precision balancing reduces wobble and vibration, so the condenser runs more quietly and maintains consistent coil airflow.

• High-hardness plastic resists cracking from road debris or thermal stress.
• Six blades are factory-balanced to minimize vibration and noise.
• Durable construction helps maintain correct airflow across the condenser coil.

Is installation difficult and what tools are required?

Installation is straightforward for anyone comfortable with basic RV maintenance: the blade is shaped and drilled to mirror the OEM part so removal and replacement follow the same steps. In most cases standard hand tools suffice and the swap can be completed in minutes without specialized equipment.

• Identical form factor to the original allows direct removal and reinstall.
• Typical installation requires a wrench or socket set and a screwdriver.
• No modification to the condenser or motor shaft is normally necessary.

What are the exact dimensions and mounting details?

The replacement conforms to the original dimensional specifications so it clears the shroud and engages the motor shaft precisely. Knowing these details helps confirm compatibility before purchase and ensures proper rotation and clearance after fitting.

• Overall diameter: 10.5 inches (measured across blade tips).
• Thickness (axial depth): 3 inches from front to back face.
• Shaft interface: 1/2-inch D-shaped hole to match common Duo-Therm motor shafts.
• Six-blade layout for even airflow distribution and balance.

Who this is for: RV owners, service technicians and DIYers who need a cost-effective way to restore their Dometic Duo-Therm Brisk II or Penguin rooftop air conditioner to proper operation. Choose this HLTIT replacement when the original condenser fan blade is cracked, warped or unbalanced and you want a part that mirrors the OEM fit and function without replacing the entire unit.
