Smoke Bomb/Grenade Ventilation Test from Shipping Container with Big Air Passive Vents.



We have a wire pull smoke bomb here, blue in color that we're going to set off inside this 40 foot high cube one-time use shipping container. This has two Big Air 45's installed up high in opposing corners, that's two less than we recommend in 40s. We'd like to see two high and two low, but nevertheless we're gonna set this thing off and show you how well this ventilation setup exhausts air out of this container and how long it takes to to exchange the air and for everything to circulate.


So here we go, I think blue might have been a bad color given the sky's nice and blue right now, just to really get a visual on how much this is exhausting. There's no fans in here, there's nothing blowing this out, this is the natural pressure of the earth creating all that smoke or exhausting everything, so when you have two vents inside your container, one's an intake one's an exhaust, and it really depends on the wind direction and the sun. Who knows, there's so many variables that would change that, but you can see here, air is moving out of this thing. A lot of times you can stick your hand up by these things and feel a good airflow, and so now this just really helps us visualize this.


Pretty happy with how this is this is exhausting, especially inside of a 40 foot. Two vents are what we suggest for a 20 foot, and four for 40 foot. We'd potentially see double this air movement if we had the proper amount of vents, and these here are the Big Air 45 vents. They're sold on Amazon or you can check out our website tcg.ca. We have all of our modification products and accessories available there. We have other types of vents there, and something that's really cool coming out shortly here, is we have a solar powered axial fan with a small solar panel that's connected to these things. So all throughout the day, as the sun's beating on your container, it will actually be running an axial fan and exhausting. The air is really pulling it out and then you pair that with two of these vents and then the other two would passively ventilate all throughout the night.


I guess what's interesting to note, this wall right here is facing due south, this is the south wall. The sun is beating on it right now and the winds coming from the west and blowing east, so if someone's planning on, or they want to really know which side to put a vent on, or especially if you wanted to control which one would be an intake or exhaust, or just know which one in this variable with a wind from the west, the sun beating on it, on a south wall, we are having this vent be the exhaust and the north vent that does not have any sun on it is the intake.


So it's been almost an hour or right about an hour, and so we want to jump inside this thing and see how well it's removed all that smoke. It produces a ton of blue powder smoke inside there so we'll see how much is left...


Smells like gunpowder in here, so yeah there's still some time to go. I wouldn't call it a full air exchange where every speck of air inside this container has fully exhausted out and exchanged, but I I wonder in a non-vented container, if we set one of these off and came back into it in an hour, it would just be like a blue cloud entirely just overtaking you as you open the door. I'm certain this has made a huge difference, and again this is only half the amount of vents that we recommend for 40s. We'd like to see a couple low as well and then you get some nice cross flow ventilation, whether it's just the hot air and cold air, or if there's any vapors in here you can exhaust fumes, that would be either heavier or lighter than air through having high and low ventilation. So that's that's definitely a recommendation if someone's looking to install these big air 45 vents, but I hope you enjoyed our little experiment here, it was fun doing it.
