8430A634 Coleman-Mach CHILLGRILL, DUCTED UNIT - COOL ONLY, BLACK

The 8430A634 Coleman‑Mach ChillGrill (Black, Ducted, Cool‑Only) is the OEM ducted ceiling assembly designed for Coleman‑Mach rooftop air conditioners. This cool‑only ChillGrill provides strong, efficient airflow through the RV’s duct system while allowing direct dump‑air cooling when needed. Its low‑profile black finish offers a modern interior look, and the assembly installs cleanly into standard 14" × 14" roof openings. Built to Coleman‑Mach specifications for durability, quiet operation, and a precise fit, it’s ideal for replacing worn plenums or completing a new A/C installation.
