AdaptAIR™ Roof Vent Adapter for Shipping Containers
Trusted by container owners for 7 years. AdaptAIR™ has been used in thousands of shipping container roof vent installs by DIY customers, builders, farms, shops, storage owners, and container modification companies who need a clean way to add ventilation — without welding or fabricating a custom roof mount.
Install a full-size 12" roof vent on your container
Standard turbine, solar, and static roof vents need a stable mounting surface. AdaptAIR creates the missing platform so you can install a 12-inch collar vent on a corrugated Conex / shipping container roof.
Why containers need real roof ventilation
Shipping containers trap heat and moisture. Without a proper airflow path, that trapped air can contribute to:
- Extreme interior heat
- Condensation and “container rain”
- Musty odors and stale air
- Rust risk and moisture damage to stored items
AdaptAIR gives you a container-specific, no-weld way to mount roof exhaust where it belongs — on the roof.
What’s included
- One (1) AdaptAIR™ vent adapter for standard 3.5" corrugation
- Complete installation kit: drill bits, driver bit, screws, abrasive pad
- Step-by-step photo instructions
Not included
- 12" vent / turbine — sold separately (fits most 12" collar vents, including Whirlybird-style turbines, solar, and static vents)
- Adhesive / sealant — use a professional-grade structural adhesive for metal
Want everything in one box? Shop our complete 20' roof vent system or 40' roof vent system — adapter, turbine, intake vents, and install kit included.
Important fit note
Fits standard 3.5" shipping container roof corrugation only. Measure between the raised and lower rib pattern before you order.
- Not designed for 3", 5.5", or 6.5" ribs
- Not intended for sidewall installation
Please check the measurement chart before ordering.
How many do you need?
- 20' container — we recommend one (1) AdaptAIR roof vent
- 40' container — we recommend two (2) AdaptAIR roof vents
Complete the airflow path
A roof turbine exhausts hot, moist air. For air to move efficiently, fresh air also needs a way in. Sidewall intake vents create dedicated entry points so the system isn’t pulling only through door gaps.
For best results, pair AdaptAIR + a 12" turbine with intake vents — or choose a complete 20' / 40' package where intakes are already included.
No-weld DIY installation
Installs with the included screws and a professional-grade structural adhesive for metal. We recommend Chem Link M-1.
- Do not use standard silicone caulk
- Do not use latex caulk or roof cement
- Do not use sealants not intended for exterior metal roofing and flashing

Frequently asked questions
What roof corrugation does this fit?
AdaptAIR™ and our roof vent systems fit standard 3.5" Conex-style shipping container roof corrugation only. Measure before you order. Not designed for 3", 5.5", or 6.5" ribs.
Do I need intake vents?
Yes for best results. Roof turbines exhaust hot, moist air. Sidewall intake vents give replacement air a dedicated path so airflow moves through the container instead of only leaking through door gaps.
What is the difference between the adapter and the complete vent system?
AdaptAIR™ is the no-weld roof adapter. A complete 20′ or 40′ vent system includes the adapter, 12" turbine, and intake vents as one package. Buy the adapter alone if you already have a compatible 12" turbine.
How many vents do I need for a 20 ft or 40 ft container?
We recommend one AdaptAIR™ roof vent for a 20′ container and two for a 40′ container. Our complete kits are sized that way.
