The luclyyasys 6733-3221 is an 11-inch, six-blade replacement fan for Coleman Mach RV air conditioners that restores airflow and cooling performance with durable, high-temperature resistant materials.

If your Coleman Camper or Mach-series rooftop air conditioner is underperforming or making unusual noises, a worn or damaged fan blade is often the culprit. The luclyyasys 6733-3221 replacement is engineered to match common Coleman part fits while using anti-corrosion, heat-resistant materials to survive rooftop exposure.
