HLTIT RV AC Condenser Fan Blade 10.5" for Dometic Duo-Therm & Penguin — 6-Blade, Impact-Resistant

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

When a cracked or warped condenser fan blade causes reduced cooling, noise, or vibration in your RV air conditioner, swapping in an exact replacement is the fastest, most cost-effective fix. The HLTIT 3310709.005 replicates the original part’s size and mounting interface so you can reinstall the blade quickly without modifying the unit. Built from impact-resistant engineering plastic and precision-balanced during molding, this fan blade helps the condenser coil shed heat consistently while minimizing wobble and extra strain on the motor.

How does this replacement blade match my Dometic Duo-Therm or Penguin unit?

The HLTIT 3310709.005 is manufactured to the same dimensional and mounting specifications used by the original equipment. Its 10.5-inch diameter, 3-inch thickness, and 1/2-inch D-shaped shaft hole align with the OEM geometry so it seats and locks like the original. Compatibility covers several part numbers and series commonly fitted to Brisk II and Penguin models.

• Exact dimensions: 10.5" diameter × 3" thick with 1/2" D-shaft hole.
• Compatible with series 3313107.015 and 3107914.008.
• Works with part references: B57915, B59146, B59186, B59196, B59516, B59530.
• Designed to match OEM mounting points and rotation direction.

Will this blade reduce noise and vibration in my RV AC?

The blade is molded with tight tolerances and then balanced to ensure smooth rotation at condenser RPMs. A well-balanced six-blade design distributes airflow evenly across the coil, which minimizes pulsation and vibration that cause audible noise. Replacing a damaged or unbalanced blade often eliminates rattles and reduces load on the fan motor.

• Six precision-shaped blades for uniform airflow.
• Molding process reduces out-of-balance conditions.
• Material choice resists deformation that leads to wobble.
• Quiet operation helps maintain comfortable cabin noise levels.

How durable is the HLTIT 3310709.005 for RV use and road conditions?

Built from a high-hardness engineering plastic, this replacement blade resists impacts from debris and does not easily warp under heat cycles typical of condenser operation. The material selection and structural design help the blade retain balance after minor strikes and extended service. You should still inspect the blade periodically for chips or cracks after rough travel conditions.

• Impact-resistant engineering plastic construction.
• Resists deformation from thermal cycling.
• Maintains balance after minor debris contact.
• Lightweight to limit extra load on the motor shaft.

How easy is installation and what tools will I need?

Installation is straightforward because the HLTIT blade replicates the OEM form factor and shaft interface. In most cases you remove the AC cover, unbolt or pull the old blade off the motor shaft, and press or secure the new blade onto the 1/2-inch D-shaped shaft. Typical installs take minutes with basic hand tools and eliminate the need to replace the entire condenser assembly.

• No special adapters—fits 1/2" D-shaft directly.
• Installs with common hand tools (screwdriver, wrench, pliers).
• Same bolt pattern and clearance as original blade.
• Quick swap saves time and replacement costs.

Who this part is for: RV owners, technicians, and fleet maintenance crews who use Dometic Duo-Therm Brisk II or Penguin rooftop air conditioners and need a reliable, OEM-dimension replacement fan blade. If your condenser is noisy, the motor is straining, or airflow is reduced because of a cracked or warped blade, the HLTIT 3310709.005 gives you an affordable way to restore proper condenser performance without replacing major components. Designed for straightforward installation and long-term durability, it’s suited to seasonal maintenance, roadside repairs, and proactive parts inventory for service shops.
