homemade shop exhaust system

home made exhaust system I built a while back. a lot of diesel engines run in shop, and shop is built very "tight" and heated/ac so don't like wasting energy leaving doors open
old furnace fan, welded adaptor onto side to my inlet. outlet was welded into a funnel shape to accept a 5" exhaust pipe which runs through wall to outside and is capped with a semi truck rain cap with a light spring to hold shut to keep outside air out when not in use
my inlet side has a T which will allow it to **** down the wall tube and into my rubber flex section, other end of t goes to ceiling with another truck rain cap and a spring to hold shut. has a manual pull cord to prop cap open to **** diesel exhaust and other continuants from ceiling.
metal pipe is "insulated" style with an airgap between the inner and outer pipe, resulting in outer pipe not getting hot

the rubber hose is 24' with a truck exhaust for a U in the middle for the length heading back towards ground, hooked to an old air hose reel with rope wound up on it, so when not in use it hangs verticle and no hose to trip on.
easily reaches my two lift bays for tailpipes.

That's impressive, was it all with parts you had on hand? Is it noisy?

super cheep and easy build to be safe in the shop.

could also do same thing for welding area dirty air removal .

Looks like a good idea. That should work out pretty well for you.

Great idea and simple design. What's it look like on the vent outside ?

works great, noise is almost non existent, so quite I need to add a "on light" so I remember to shut it down. you can see the access panel I installed to access wheel after I sucked a plastic bag into it because of my old man plugging hose to make top **** harder

had to buy all the insulated pipe but that was very cheap, the 4" exhaust hose not so much! $250 in just the hose, but it has to sustain high temps for diesel exhaust, it will get so hot that you cant handle it when running a truck on high idle trying to make heat in the engine

That is really cool and you shop is nice. Is it a commercial shop or a hobby?

Fantastic! Warming up my Liberty CRD can be a real hassle. A heated garage would be nice to wrench on it in!

Something goes wrong you're going to be on the hook for it. Just saying. Don't know if you got employees but you gotta be careful with this stuff in a commercial setting.
