    Question Canopy air vents for positive pressure

    Was looking around for some air vents or “scoops” for my canopy and found 4x4direct sell a few...

    https://4x4direct.co.za/538-air-vents-and-handles

    Not sure which would be better to get as I seem to accumulate dust from the rear door.

    Anyone here with experience with the vents? I don’t care about the price difference... just whichever one works best. They all seem easy to install.

    That bottom one of R640 works. https://4x4direct.co.za/air-vents-an...-canopies.html

    Did a 10 day trip with that one on my canopy in Moremei and Kwai. No dust even with no extra sealing of the load bin.

    I also used the aluminum one. Closed day to day and seals well. Open on dirt roads to make a positive pressure inside the canopy. Also seal the tailgate as this also helps

    I just open the sliding window next to the cab.

    Thanks, unfortunately I don’t have a sliding window on the Alu-Cab.

    Seems like the alu one is the one I’ll get.

    I've got the alu one...

    just to note, even with the vent, if you don't seal the tailgate, you'll still get dust in the back

    popup drain plug. Like the one you have in your bathroom sink. Easy to install, is made to be waterproof.

    I've done a few for friends and my previous 2 canopies.

    I always install it facing forward in one of the top corners.

    Will see if I can find a picture.

    Edit: Found some.

    Great Idea - will use it in Future.
    Cutting the square hole for the alu vent can be quite a pain. With the round drain plug, you simply use a hole cutter. And you can add additional ones if required.
    If you have a single (square one) you have to be careful of how you pack the stuff inside the canopy, so as to not block the opening or hinder airflow. Hence the fact that more than one small one may be of help.
    Also, be careful of critters seeking out the heat generated by you fridge, entering through the large hole. One again, the drain plug may prevent this.

    That drain plug idea is brilliant.
    I recall someone once posting a pic of a canopy with a snorkel.

    Thanks for that, this will probably work well on my trailer

    I have also installed the popup alu one. It works like a dream. Got one at the local trailer parts place for a lot cheaper than R640.

    Like the others have said the popup alu one is the winner

    At first I tried the Badger circular one, the vents sit too close to the canopy body and don't seem to scoop up any air at all.

    Jip, this one works well. But try to seal your tailgate just so that less air escapes than what the scoop forces in. Positive pressure equals no dust...

    Without hijacking/derailing the thread: Is there any vent one can use on a canvas canopy?

    Just make a small window in front which you can close with velcrow, mine worked like that for many years and min dust in the back.

    On my aluminium defender canopy, i drilled a large hole (+-80mm) on the front left and right corners. A box was then riveted over this hole both on the front and inside. The bottom of the box on the outside/front was open, and top of the inside box was also open. This prevented rain from entering. Very cheap to make,

    Hi all

    This thread is a good example of why I love this forum.

    I had issues with dust in the canopy and until I read this thread, it hadn't occured to me that I could do something about it.

    Thank you all!

    Here is what I did:

    Drilled a 40mm hole on each side of the canopy at the front
    Inserted 40mm compression type tank adaptors as used in JoJo tanks
    Hand tightened 40mm tank plugs
    Cost: R110 and 20 minutes.
