Patented airflow design
A watertight container can still leave what’s inside wet.That’s why we designed the XL Vent Container.
Moisture can condense inside a container even when no rainwater gets in. Our patented airflow features help reduce the risk of condensation and dampness.

The problem
What causes condensation inside a container?
When warm air meets a cold surface, such as the steel roof and walls of a container, water vapour in the air can condense into droplets.
That matters most when a container is used for long-term storage, because damp can lead to mould and damage to what’s inside.
Good ventilation helps move moist air out before it settles. That’s the idea the XL Vent Container is built around.
How it works
Three sets of vents, working as one system.
Air can move through the container from the doors, the front wall and both sides.
-
Patented
XL Vents
Two large vents in the doors, each with 516 perforations. A labyrinth design inside helps keep rain out while air moves through.
-
Patented
Recessed airflow rail
A vented rail set back into the front wall. Because it sits back from the wall, air can still pass when the container is placed against another container or a building.
-
Standard
Side vents
A series of vents along both sides of the container adds further airflow to the system.
Placed tight against other containers or a wall?
Self-storage sites often line containers up end to end or against a building. The recessed airflow rail sits back in the front wall, so the container can go right up against something and air still has a way through.
Also built in
Built to help protect what you store. Designed for everyday use.
-
Damp Defence floor
A protective PU coating helps reduce water absorption through the wooden floor’s surface. Alongside the XL Vent Container’s patented airflow features, it adds another layer of defence against damp.
-
Security lockbox, already fitted
A steel lockbox shields your padlock from tampering, fitted as standard.
-
Waist-height locking bars
Easy-open handles at waist height, so there’s no bending down to open or close the doors.
Nothing extra to pay for the XL Vent Container features. They’re included on new standard and high cube 20ft and 40ft containers, subject to availability, and covered by our best container price guarantee*.
Who it’s for
Self-storage is their business. These are the containers they chose.
You can choose the same XL Vent Container for your own stock, equipment or personal belongings.
“I recently had to move a customer from a container purchased from another supplier as he was suffering with condensation issues. The XL Vent containers are far superior. I wish I could change all of the containers I previously ordered to Adaptainer containers.”
“Really happy with the containers and the XL Vents make a noticeable difference.”
-
Self-storage operators
Place containers side by side and end to end, and the recessed airflow rail still gives air a way through. Storage your customers can see the thought in.
-
Storing your own things
Load up, close the lockbox and let the airflow features do their job. Waist-height handles make getting in and out easy.

Do I pay more for the XL Vent Container features?
No. There’s nothing extra to pay for the XL Vent Container features, and new containers are covered by our best container price guarantee.
Will air still get in if my container is against other containers or a wall?
Yes, that’s what the recessed airflow rail is for. It sits back in the front wall, so air can still pass through when side or front wall vents are blocked.
Can I just open the doors now and then to let air in?
Opening the doors lets moist air in, and if it’s trapped when you close them it can condense. That’s why steady airflow matters: the vents help keep air moving after the doors are shut.
Will it stop condensation completely?
No container can rule condensation out completely, because it depends on the weather, humidity and how the container is used. The XL Vent Container’s patented airflow features help reduce the risk of condensation and dampness.
Are there other ways to help reduce condensation?
Yes. Options such as Grafotherm coating or insulation can be added at extra cost, typically from several hundred pounds to several thousand per container. Good airflow is the simplest place to start.
Which containers come with the XL Vent Container features?
XL Vents and the recessed airflow rail are included on new standard and high cube 20ft and 40ft containers, subject to availability.
