Floor Vent Details

Lots of people talk about putting vents in/through the floor, or using the existing vent locations at the rear corners. I'm interested to know how this has worked out, and most of all how you keep water, dust, critters, and anything else that isn't "AIR" out.


It seems we're mostly past the freezing point here in SW Ontario so I can get going on the stuff that involves putting holes through the sheet metal, painting, and sealing.


Any other tips, tricks, suggestions that are relevant would be appreciated.

The floor hole in my conversion is open 95% of the time. Close it on dusty roads and at night in cold weather.

Have a screen to keep out the critters. The location just in front of the diver side rear wheel does not get water inside.

There comes a point when it becomes pointless to keep explaining what you did over and over.

Consider the climate difference between my location and most of "y'all". The last thing I want is for any floor vents to become covered by frozen slush in the winter. Actually, call that second last. The last is the intrusion of water through or around the vent.

This will not be passive, rather it will be connected to a heat recovery ventilator.

Here's some detail on another method, similar to Orton's. with a filter under the van and a blast gate with remote cable to restrict dust, critters, and such, as well as close it completely when desired.

I have one possibly 2 of these planned in a design. I don't want to cut a big hole in my ceiling for a vent/fan. Holes in the floor have problems all of which can be overcome with screens, filters and dampers that get closed in the winter. A small cover could be made so that the opening pointed to the rear of the vehicle to block most of the large stuff like ice and water.

If you are referring to my post, I think it is obvious that the OP had not found any information on a floor vent. The reason for posting is to try and give the poster information.

Fail to see why posting multiple times to interested people is a crime. Why is it a problem? If others have read the information they can simply skip reading the post.

Keep in mind how air must flow to get any benefit from a vent. Having high and low openings can make use of convection to move the air. Otherwise, only a fan pressurizing (or depressurizing) the space will circulate air from outside, to inside, then back out again.

Having openings at either end of the living space gets air moving across the space with a better chance of reducing stagnant areas due to the flow path. If both vents are too close together the air in the living space won't be circulated as effectively.

Give thought to how it will perform the job early on in the design stage and make the best use of vents, fans, and physics to maintain a comfortable living space.

Fellow forum *addicts* should be tolerant of each other about such things. They are likely the only ones who realize that is what's happening.

I stayed away from this forum for quite a long while until recently showing up again to find lots of new people and as you may have noticed I've gotten sucked in now and then to re-posting stuff I know is elsewhere in the forum quicksand.

It triggers a twinge of guilt every time I do it.

Good point – Orton is addressing the needs of those who don’t want to or can’t search out all the prior history on things. I appreciate that surly Bill has at least consolidated the tire stuff. Does anyone know if we can post stickies for the most common subjects? The sticky itself could simply be a post with links to all the various forum threads about the same things over and over again.
