Exhaust fans are used in many attics and commercial buildings to draw out warm air out of the structure causing a cooling effect and air draft for that space. As you can expect, a dog box or trailer will warm up fast with a dog’s body heat. Exhaust fans or blowers can be easily installed with minimum cost and effort.
I decided to share my project as an example for you to have an idea how to install blowers in your box or trailer. Of course your box design may vary from mine. My dog box is a Creative Sports Model DT700. It is a 3 hole with a 5” storage compartment on top giving me sufficient space for the install.
My concerns of installing the fans were to keep them out of the weather and all wiring out of the area of the dogs to prevent chewing. All components are inside the storage compartment. I installed the switches outside the box so I would not have to open the storage compartment to turn the fans on or off. I used rubber grommets to protect the switches on the out side the box. Cowl vents are the key to getting the air outside the box without exposing the blowers. I used a rubber coupling to connect the blower and cowl vent.
Another key factor is having the option of taking the dog box out of your truck or SUV. You need something that quick connects the wiring from your battery to the box. I used 24V Trolling Motor plugs for this connection. The plugs are simple, waterproof, and reliable.
Holes are drilled in the storage floor bottom / dog space top, such that the air can flow up out of the dog space. I mounted my two blowers so that each of them would take air from two dog spaces or in other words, on the centerline of the dividers. The bowers are used to take air outside the dog’s space on non-windy days or while traveling. On windy days, simply open the storage compartment to create a breezeway.
Please scroll down for step-by-step demonstration of how my project was done. I hesitate to give you any dimensions. I created this page only as a guide for your project. You will have to get creative and work out the details for your box or trailer. You can click on any of the pictures for a larger view. Also I will answer as many questions that I can through email. Good Luck!!!
