While not every storage container needs to be ventilated, but certain environments need ventilation.

In this article, we’ll look at what ventilation should be used in storage containers and whether you need a vent for yours.

Does My Storage Container Need Ventilation?


When using a shipping storage container, it may surprise you to see that there are vents already included.

These vents are known as pressure vents that help to circulate air within the container.

However, these are not proper ventilation ports.

Poor ventilation can damage your items that are inside it and can be harmful in environments where people may be in.

Harmful issues caused by poor ventilation include:

  • Condensation, which is water vapor on a surface. Condensation is what helps lead to mold.
  • Mold, a type of fungus that can cause harm if inhaled. Mold is also very expensive when removing if left untreated.
  • Air borne diseases, like pneumonia and respiratory diseases, are often caused by poor ventilation.
  • Rust, which is a result of a build up of condensation. This can cause damage to the container itself, but also any metal pipework that has been installed.
  • Odor, such as musty smells. This is due to the dampness and lingering scents.

Now that you understand what poor ventilation can mean to your storage container, let’s look at the different types of ventilation you can use.

Types of Ventilation


There are three types of ventilation that can be used in your storage container – rooftop turbine, fixed louver, and exhaust fan.

Let’s look at all three.

Rooftop turbine vents

Rooftop turbine vents are an inexpensive option, as well as a popular one for storage container ventilation.

These vents are mounted on the roof and can be placed in multiple places on the roof’s surface.

Because there’s no power required for these types of vents, they are often used for storage container owners and renters who might be on a limited budget.

They’re good for storing temperature sensitive items.


Fixed louver vents

Louver vents are available in different sizes and are normally installed along with exhaust fans. They can also be installed without exhaust.

These types of vents allow air to pass through while also keeping out unwanted elements, like dust and water.

Fixed Louver Vents for Storage Container Ventilation

Louver vents can also come with screens to help block out weather elements and unwanted pests. They rely on natural airflow.


Exhaust fan vents

Like rooftop turbines, exhaust fan vents can be placed in places other than the roof of a container.

These vents tend to be a bit smaller, which allows them to be place anywhere on the storage container.

When to Use Storage Container Ventilation


We’ve looked at what can happen when you don’t ventilate your storage container and the different types of vents that you can use.

Let’s look at when you would want to use storage container ventilation.

We mentioned earlier that not every storage container needs to be ventilated, but it depends on what you’ll be using the container for.

If you’re planning on storing non-temperature sensitive items, you could get away with just using a storage container that may already have pressure vents.

Equipment like lawn materials or athletic equipment are best suited for these types of storage containers.

These also work best in moderate climate locations.

You should use storage container ventilation whenever you store materials that could be damaged by additional heat or moisture.

Household items, for example, should be stored in a conex box with ventilation. This is important during home projects, like renovations or remodels.

Dry goods are another item that should have proper airflow.

Shelf items can rot due to condensation, which can degrade the food or liquid inside. Residents or businesses that use portable pantries should have ventilation.

Shipping storage containers have been popular additions for construction sites, both in terms of storage and mobile offices.

Mobile offices and temporary workspaces have an increased popularity.

This allows businesses, entrepreneurs, and freelancers to work in a professional capacity without renting expensive business spaces.

When using storage containers as workplace, proper ventilation may be law within your city or state.

This ensures that all employees and staff are working in a habitable, non-harmful environment.

In this article, we answered the common question of “does my storage container need ventilation?”

While the situation might depend on what is being stored, in many cases you will want to make sure that your storage container has proper ventilation.

Installing vents within a container helps to maintain the airflow within, keeping items and people safe from harmful effects.
