The Cool-J 5m Ducting Kit Stops Your Underbunk Air Con Cooking Half the Van
60mm ducting, 3 outlet vents, black or white - built for Cool-J underbunk air conditioners
Aircon's running, compressor's humming, and the back of the van is still an oven. Nine times out of ten it's not the unit - it's tired, perished or missing ducting bleeding all the cool air out before it reaches anywhere useful.
This is the fix: 5 metres of proper 60mm ducting plus 3 outlet vents, made by Cool-J for their underbunk air conditioners. Run it once, get airflow to every bunk, done.
Why Vanners Rate the Cool-J 5m Ducting Kit
- 5 metres of 60mm ducting. Enough to run one main line to a set of outlets without joining short offcuts together.
- 3 outlet vents included. Spread the airflow to the front, middle and back of the van instead of one hot spot near the unit.
- Black or white to match your interior. Not stuck with whatever colour the last supplier had in stock (no offence, Dave).
- Genuine Cool-J part. OEM code 3J-KCR2200-U, made to fit Cool-J underbunk air conditioners.
- DIY-friendly. No special tools - cut to length, push-fit the vents, done in an afternoon.

Will This Fit Your Air Conditioner?
This is a genuine Cool-J part (OEM code 3J-KCR2200-U), made to suit Cool-J underbunk air conditioners. If you're not sure it matches your unit, measure the duct spigot before you order or give us a call on 03 7056 6732 and we'll check it with you.
Why 5 vents can beat one
A lot of underbunk installs run one short duct straight up near the unit and call it done, which is why the front of the van cools down while the back stays warm. Splitting the airflow across 3 outlets spread through the van gets even cooling instead of one cold spot and two warm ones. It's a bit more cutting and fitting up front for a much more even result every trip after.
Not Sure If This Is the Right Ducting Kit?
Go the 5m kit if you're running one main duct run with a single split to 3 outlets in a smaller van or camper. If you need to reach outlets at both ends of a longer van, look at the 10m kit instead so you're not joining lengths of ducting together. Still not sure? Call the store on 03 7056 6732 or send an SMS to 0476 330 590 and we'll talk through your layout.
