Description
BigAir Louvered Container Vents are engineered to be installed anywhere on shipping container sidewalls, end walls, or doors - from floor to ceiling.
BigAir Louvered Container Vents (sizes: 30 & 45), 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). BigAir60 Vents do not come with a marking guide.
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 is suggested. 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 BigAir will never rust!

I'm not that skilled cutting long vertical lines with a cutoff wheel, so I made me a simple guide out of 1 1/2" light angle. I used the Big Air 60 vent as a pattern, welded the pieces together and drilled holes in each corner. I then went and purchased the corded 6" angle grinder from HFT (on sale, of course), since that grinder is perfect for this type of work. It seems like a 4 1/2" is too slow, and my 9" grinder is way too heavy... although I did try it. I hold the template in place and drill the first hole in the upper right corner and attach with the supplied screws. Then I drill a couple more holes and put more screws in to secure it. I then use it to keep my wheel straight and grind away. It worked out really great, since I have 4 Big Air 60 vents to install; one in each 40HC container. I then remove any burrs with a flap wheel on a 4 1/2" grinder. The holes in the Big Air 60 are perfect in that for all 4 vents I installed, the holes were always exactly the same and the pattern worked every time.
I live in Texas, so it gets hot in the summer. I purchased a 2-Pack of the BigAir 60 Louvered Vents with the bug screens. I have seen YouTube videos where the person makes their own bug screens, but the bug screens from CMW are fabricated and rivetted in, so it is a much cleaner installation and only a little more. I love the fact that not only does the "Container Guy" have an installation video, but they come with printed instructions. These vents are very well made. The kit comes with a couple bags of 3/16" diameter X 1/2" long rivets; enough to complete the installation. They fit perfectly and only require some caulking around the top and bottom to finish the job. I installed a Whirlybird 13 feet from the end of my 40' HC container and a BigAir 60 on the shady side near the door. I placed the BigAir 60 on a corrugation to clear the door so it would not smash into the vent if the door was swung back too far. I followed the directions, and everything went according to plan. Very pleased with these vents and plan to purchase another 2-Pack of BigAir 60's for my other 2 containers.
