What it does

Move air so storage stays usable.

Vents and fans help reduce trapped heat, moisture, fumes, and stale air inside shipping containers.

Passive or powered airflow

Choose louvered vents, roof vents, solar vents, or exhaust fans based on the container use and airflow target.

Helps manage moisture

Better air exchange can help with condensation risk when the stored contents or site conditions need it.

Match the opening

Confirm cut size, placement, hood direction, and whether the unit needs power or sun exposure.

Install notes

Plan high/low airflow paths before cutting the container.
Seal all cut edges and fastener penetrations to protect weather-tightness.
For powered ventilation, confirm electrical requirements, controls, and trade support before install.

BIG AIR® Louvered Container Vents are engineered to be installed anywhere on shipping container sidewalls, end walls, or doors - from floor to ceiling.

BIG AIR® Louvered Container Vents (sizes: 30, 45 & 60), come with a marking guide to make cutting a hole as easy as possible! Rivets (Alum/Alum, 3/16", 1/4") and self-tapping screws are also included (we recommend using rivets).

A minimum of two vents are required per container for temperature & moisture control in temperate climates. Four vents per container are suggested in tropical climates. For HAZMAT ventilation, two vents installed high and two vents installed low are suggested. It is the customer's responsibility to ensure OSHA compliance when storing hazardous materials.

Eliminate moisture and excess heat with our state-of-the-art computer-modeled design. Made with highly durable Polypropylene and Aluminum, the BIG AIR® will never rust!

The variables inside a shipping container are always changing. When the combination of those variables creates an environment prone to humidity, condensation will happen.

The above-mentioned variables include, but are not limited to the following:

Humidity
Interior temperature
Exterior temperature
Wind direction
Wind speed
Foundation
Adequate airflow under the container
Direct sunlight to roof
Direct sunlight to walls/doors
Type of contents stored
The volume of contents stored inside
Color of container
Number of stock vents in the container
