Coleman Mach Duct Divider 84303012 | RV AC Part — Product description
The genuine Coleman replacement duct divider for Mach air conditioner ceiling assemblies built with lateral ducts. It's the single molded piece that splits conditioned air between the left and right duct runs, so cool air spreads evenly through the coach. Part 84303012, sold on its own.
This is the duct divider for Coleman Mach air conditioner ceiling assemblies built with lateral ducts. It's the single molded piece that splits airflow inside the assembly and sends conditioned air down the left and right duct runs instead of dumping it all in one spot. Small part, but it's the reason a ducted system spreads cool air evenly through the coach.
If yours cracked, warped from heat, or went missing during a ceiling assembly swap, this drops right back into place. It's sold as a single piece, just the divider, not the whole ceiling assembly. So order it when the divider is the only thing you need and you don't want to pay for parts you already have.
We see these come up when folks are servicing an older Mach ducted setup and find the original divider gone brittle. Match the part number to what you pulled out and you're good. Coleman part 84303012.
