Did a search for a flue system, but could not find any thing....

Looking for pics and Ideas for blowing the exhaust out the top of my enclosed trailer....

Right now I have nothing, I know, I know, I am supid, but just need to get around to it, summer is killing me with heat in there...

mounting is what I am looking for, worried about traveling 75 mph down the highway and losing cap, plus shifting weight and bounce of duct on the inside....

Thanks in advance,

Matt
 
I would look at some vent systems used in the mobile kitchen industry - caterers, concession stands, etc. I have also seen some nice fan systems that mount on the side of the trailer. they are very low profile.
 
Here is an 8 inch flue adapter. This is very heavy steel that screws to your exhaust on your machine. I use self tappers but most have holes already there... ie- miTm, Tuff, Landa..

We have these available in out store soon to be on our site. They come with a gasket that mounts between the two. I drill a hole in this and ad the engine exhaust. I can show you how to do that too.

I build these trailers weekly so I have exhausted many. This next one will be 8" B-vent pipe with a standard furnace lid. Because this is not really made to travel, I am building a small ramp in front of it to throw the air up over. This will be out of sheet metal and have to be screwed to the roof and then sealed. We'll put wood inside the trailer and do it right the first time. It shouldn't leak and will be effective. I then drill the hole in it and walla I ad the 1 1/4 hose coming off the briggs and screw it to the inside of the pipe. Everything then exhausts.

I have done many others also but yet to come up with a surfire one step exhaust system for trailers.

Here is a picture of the vent.

Here's one

This works great for travelling but not real well when it's raining and sitting still. We are learning all the time also so posts like this help us all. You'd be surprised how many people just let the exhaust in the trailer or van. I know of many.

I have heard that you need a gap of about a inch, from the machine and duct work to properly vent your system....

Justin, What is your opinion of performance after set-up of your machines that you build, with the duct up against the machine?

I also like big petes Idea, looks low profile for sure...

Well, I don't have that gap that everyone says I need. I have never had any problems with that. I've been venting machines for years and this method seems to work. That other method may be better and if it is, I'll switch for sure but these same flue adapters will work for that also. I'll just make an adapter or cut some of the adapter out to act as a draft.

I must do a little research on this. Anyone that know's for sure should speak up because these are manufactured and intended to do just what they do. The manufacture must have some sort of knowledge of this. If so, why wouldn't they creat the amount of draft needed?

I will look into this further.
 
Great thread............I have to vent my box truck soon.

Justin, is that roof vent facing the rear so the rain won't get in while driving?
 
That was the purpose, yes. but it's probably not the best resolution for it. It is more like a heavy duty dryer vent. It does work but I have another idea that's a little better yet.

I am builiding another trailer so I'll find a better way. Suggestions are definately helping.
 
Justin, How much do you sell the adapters for your flues?

Also look under exhaust mod. in a search mode, there you will find about the gap I was talking about on flue systems...

Email me or go to my website and I have pictures of them in new products section. The store is not up yet but pictures and price are available in the forum.
 
roof vent cover

Justin,

If your concern about that roof vent in the picture is that rain will go into it, take a look at building something like the cover used on RV roof vents. The pic is plastic, but you could easily fabricate a metal one.

Just an idea, what if you did the vent somewhat like Justins but had the gap between the vent and machine, which I do think you need, and instead of having a fixed vent on top of the trailer, you had a sliding piece of round duct that you could slide up a few inches out a hole in the top of the trailer when in use, then slide down a few inches and the top of the trailer would have a lid that would close. Sounds good to me. Hey, did I just invent something? lol

I need this flue adapter. I need to buy one ASAP. Any distributors on here sell them?
 
You could also look into something like what the big rigs have....18 wheelers......on there exhaust stacks....may even stop in one of the parts places and see if they sell just the top section and fabricate it to your exhaust.
This way it opens when your machine is running and closes by itself when it is not.......prob pick up one at a muffler shop.
