Product Features & Fitment

This replacement interior ceiling plenum features contemporary low-profile Euro styling designed to sit tightly against your coach headliner, easily concealing older ceiling imprints, screw holes, or weathering marks left behind by legacy configurations. Conditioned air is systematically channeled forward and aft through adjustable dual-direction dampers, allowing travelers to quickly zone air delivery or open the louvers for an instant localized thermal dump into the primary living cabin. The smart design features dual pop-out retainer grilles that afford rapid, tool-free access to the washable air filters, helping to minimize routine maintenance times while actively preserving downstream evaporator coils from airborne lint and debris. It provides exceptional out-of-the-box compatibility with a wide cross-section of rooftop air conditioners, including the Coleman-Mach 1, Mach 3 Plus, Mach 15, Mach 8, and Roughneck series.

It is important to note that this package is structured strictly as a plenum housing kit only and is intentionally supplied without an internal control box, wall-mounted thermostat, or electric heating element. To complete a full operational system installation, this assembly must be paired with an appropriate 12V control kit (such as the 9330C755) and a matching wall thermostat (such as the 8530A3451 or 9420A382).
