Coleman Mach 6-Inch A/C Duct Divider 8330-3612
Coleman Mach 6-Inch A/C Duct Divider 8330-3612 — Product description
This is the genuine Coleman Mach 6-inch duct divider, part 8330-3612. It's the piece inside a ducted rooftop RV air conditioner that splits conditioned air between the supply runs. When the original cracks with age, airflow goes lopsided. Swapping in a fresh divider is a quick, cheap way to get balanced cooling back.
If your Coleman Mach rooftop air conditioner isn't pushing air evenly through the coach, a cracked or missing duct divider is a common culprit. This is the genuine Coleman Mach 6-inch duct divider, part number 8330-3612, and it's the piece that sits inside the ceiling assembly to split conditioned air between the supply ducts.
It's a small part that does real work. The divider keeps airflow balanced so one run doesn't hog all the cold air while another barely breathes. When the original gets brittle from age and heat cycling, swapping it in is a quick fix that gets your ducted system moving air the way it should.
This one's built for Coleman Mach ducted air conditioners. If you're chasing weak airflow at one of the vents, it's worth pulling the ceiling shroud and checking the divider before you blame the blower. We'd rather sell you a nine-dollar part than a whole new A/C.
