The RV Airflow System is a non-electrical, non-mechanical device that improves airflow by capturing 100% of the air the A/C unit discharges and directs it into the RV ductwork. It reduces A/C noise by almost a quarter (3 dB) and is lightweight. Grand Design has been installing RV Airflow on Coleman AC’s at the factory since June 2020 . The system is composed of high-density, 3-pound extended polystyrene (EPS), custom shaped to correctly fit the air conditioner model. The shape of the primary isolation unit depends on your air conditioner model. The RV Airflow System is designed to improve the airflow of your AC’s output, if you have a ducted system . The optimized airflow reduces A/C noise by almost a quarter (3 dB), so you can actually enjoy the peace and quiet of nature . The community-reported measurements vary, but you should expect from 5 to 25 decibels in noise reduction. This will vary by the model, age, and the current condition of your AC unit. The RV Airflow’s EPS construction does not absorb water, which eliminates the potential for mold. The module is lightweight and won’t increase the load on your RV .<iframe width="560" height="315" src="https://www.youtube.com/embed/UzRU40UhuvQ?si=jTFPWkU-KUwvp-G_" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" allowfullscreen></iframe>
