Coleman Mach Duct Divider Package | 8330-3501
Coleman Mach Duct Divider Package | 8330-3501 — Product description
This is the duct divider package for Coleman Mach ducted rooftop air conditioners. It's the internal partition that keeps supply and return air separated inside the ceiling assembly, so a ducted Mach 8330, 8370, 8430, 8530, or 8630 actually pushes cold air down the ducts.
This is the duct divider package for Coleman Mach ducted rooftop air conditioners, the internal partition that turns a bare ceiling assembly into a proper ducted system. If you're servicing a Mach 8330, 8370, 8430, 8530, or 8630 and the old divider is cracked, warped, or went missing during a previous repair, this is the part that gets your airflow behaving again.
Here's what the divider actually does. Inside a ducted install, cold supply air has to go one way and warm return air has to come back another. The divider is the wall between those two paths. Lose it, or drop in a ceiling assembly without one, and the unit short-cycles its own cold air straight back into the return. The result is a rooftop AC that runs and runs but never really cools the coach. Get the divider seated and the supply air goes where it's supposed to, down the ducts and out the registers at the far end of the rig.
It's a Coleman RVP part, so it fits the matching ceiling assembly without trimming or shimming. The fit is what you'd expect from the factory divider. If you've ever fought a panel that didn't quite seat, you'll appreciate that this one just goes in.
A couple of things worth knowing before you order. This is the divider package only, not a complete ceiling assembly and not a full air conditioner. It's the internal duct divider that a ducted ceiling assembly needs to work right. If your Mach unit is set up as a non-ducted, ceiling-discharge system, you don't use a divider at all, so make sure your coach is actually ducted before you buy. And check your model number against the fitment list. The 8330, 8370, 8430, 8530, and 8630 share this divider, but if you've got a different Mach series, check with us first.
Not sure whether your setup is ducted, or which ceiling assembly you're working with? Send us your model and serial and we'll sort it out. We rig these up all the time, and we'd rather get you the right part once than have you guessing at the parts counter.

Frequently asked questions
What exactly is this part?
It's the duct divider package, MPN 8330-3501, that fits inside a Coleman Mach ducted ceiling assembly. It's the internal partition that separates supply air from return air. It is not a complete ceiling assembly and not a full air conditioner.
Which Mach models does it fit?
Coleman Mach 8330, 8370, 8430, 8530, and 8630 ducted rooftop units. If you've got a different Mach series, send us your model number and we'll confirm the right divider before you order.
Do I need this if my system is non-ducted?
No. Non-ducted, ceiling-discharge setups don't use a divider at all. This part is only for ducted installations, so make sure your coach is actually ducted first.
What happens if the divider is damaged or missing?
The unit short-cycles its own cold air back into the return and never really cools the coach. It'll run constantly and still feel warm. Putting the divider back in restores proper airflow down the ducts.
Does it include the full ceiling assembly?
No, this is the divider package only. If you need the ceiling assembly itself or other interior components, those are separate parts. Ask us and we'll point you to the right ones.
Will it fit without modification?
Yes. It's the factory Coleman RVP part and drops into the matching ceiling assembly without trimming or shimming.
