New – Big Air 45 Louvered Gable Vent with Bug Screen (2 Pack)


The new BIG AIR 45 Container Vent with Bug Screen is engineered to be installed anywhere on shipping container sidewalls, end walls, or doors – from floor to ceiling.

► Other vent designs can only be installed tight up against the top rail of containers and stick out up to 4″ causing the container doors to damage the vents when they fully swing open.

► Other vent designs that protrude add width to a shack or sea can which may require the need for over width permits to transport.

The BIG AIR 45 comes with a 9′ x 14′ marking guide to make cutting a hole as easy as possible! Rivets and self-tapping screws are also included (we recommend using rivets).

Eliminate moisture and excess heat with our state of the art computer-modeled design. Made with highly durable Polypropylene and Aluminum, the BIG AIR 45 will never rust!

Our high-quality Bug Screen Attachments are easy to remove and clean!

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
► Specifically the roof
► Number of stock vents in the container

Unfortunately, stock container vents are not enough to prevent condensation. Typical used containers have between 2 and 4 vents and the actual total air passage hole is about the size of a dime. These vents are designed to keep seawater out and are meant more as a method to equalize pressure than exchange air.
