Cold fingers? Let’s get you back to work.

Vent Link is a structural heater pass-through designed for routing warm-air ducting cleanly through rigid walls, panels, enclosures, campers, trailers, workshops, and other off-grid heating setups.

Instead of pushing flexible duct through an oversized hole or building a one-off collar, Vent Link creates a defined interface through the barrier so the heater can connect on one side and the duct can continue on the other.

The system uses a magnetic interface for fast connection and removal, making it easy to set up, tear down, or reconfigure without rebuilding the pass-through each time. A removable cover plate closes the opening when the system is not in use.

Printed in carbon-fiber-reinforced polycarbonate, Vent Link is built for dimensional stability, repeated heating cycles, and field use where common low-temperature plastics may soften or deform over time.

Full Kit Includes

2x Vent Link hose couplers
2x structural interface brackets
1x magnetic face plate
4x mounting bolts

Optional kits available without the face plate.

Designed for 4" flexible ducting.

Designed as part of a modular ecosystem. Pair Vent Link with additional Aetherium heater components and 12V DC accessories to build a cleaner, field-ready off-grid heating setup.

Engineered for those who live off the beaten path.
Proudly designed and tested in the Pacific Northwest, USA.

Every order supports Aetherium Innovations and our mission to develop tools and systems that lower the barriers in the skilled art trades.

Couldn’t be happier with how my interactions with this company went. Christian is a true visionary. I was immediately drawn to the design — there are other products out there that do the same thing, but this one just looked better.

I reached out to Christian with an idea for one add-on that wasn’t originally part of the design and would make it a more complete solution. He turned it around in one day, got it dialed, and I placed the order right away.

The first weekend it arrived, I mounted it up and test-ran it. The diesel heater connections completely exceeded my expectations. One of the biggest pain points with diesel heaters is the setup and connections, especially with a rooftop tent. With these brackets, it now takes me maybe 5–10 seconds to get everything connected and ready to go.

Will be doing more business soon.
