Replaces: 8330-763

The 8330A763 Coleman‑Mach Ducted Ceiling Assembly (White) is the OEM interior air distribution box used on many Coleman‑Mach ducted rooftop A/C systems. It delivers conditioned air into the RV’s duct network while providing a clean, low‑profile interior finish. This assembly includes the directional louvers, return‑air grille, and integrated filter access, making it a complete replacement for worn or yellowed original ceiling assemblies. Its white finish blends with most RV interiors and is designed to fit standard 14" x 14" roof openings used across Coleman‑Mach ducted installations.

This model is part of the manual ducted ADB family, commonly paired with Coleman‑Mach 8xxx and 9xxx series rooftop units. It supports ducted cooling airflow, houses the return filter, and mounts securely to the existing ceiling frame. RV technicians choose this assembly for its durability, OEM fitment, and straightforward installation.
