Coleman Mach 1/3/10/15/Q RV AC Duct Upgrade Kit

Upgrade your Coleman Mach 1, Mach 3, Mach 10, Mach 15, or Mach Q rooftop RV air conditioner with this Glorence RV AC Duct Diverter. Designed specifically for ducted ceiling systems, this airflow improvement kit addresses common cooling issues like weak airflow, uneven temperature distribution, and noisy turbulence caused by poor duct design. By optimizing air distribution, it helps restore balanced cooling, reduce airflow loss, and enhance overall performance from your existing RV AC unit.

Engineered from high-strength, rigid plastic, this component is built to endure the demands of RV travel—resisting vibration, temperature fluctuations, and long-term use. Installation is straightforward and requires no permanent modifications: simply remove the AC cover, align the duct connections, seal the joints, and reinstall. Verify your AC model and duct layout before purchasing—this kit is not compatible with Mach 8 units, Dometic, Furrion, GE, ChillCube, non-ducted systems, or center-line duct configurations.
