Exhaust ventilator for MC garage

[yamagrl]

Check this out! It works great!

 

Now I don't have to open the garage door and let the air conditioning out. And there is Zero exhaust escaping inside.

 

 

Kitty Litter pail

Small double squirrel cage

2@ 4 inch x 20 ft aluminum collapsible ducts

2@ 4 inch connectors

Half dozen self tappers and couple of zip ties

And about an hour labor

Ingenious for the home shop. Cheap too.

 

Very similar to mine but a smaller scale. Mine is two deheaded 55 gallon barrels welded together on a rolling barrel dolly utilizing two six inch air ducts but I work on semi trucks. The top barrel is a removable end type retained by a clamp. The fan is a 10" explosion proof axial flow unit and moves a lot of air but an installed VFD regulates the speed. My shop is a bit larger than the home garage so it works well discharging through a port on either sidewall.

 

It's nice to run trucks inside and not choke on the fumes.

The air conditioning in garage part kind of threw me for a loop. Up here in da U.P. we don't want the cold coming in!

Down here in L.A. (short for Lower Alabama...that's what we call the Fla panhandle) we don't want the cold getting out!

Perhaps a stupid question but wouldn't it create a vacuum, increasing the breathings thru the motor and creating false adjustments on the carbs?

It doesn't seal around the exhaust pipes. I designed it after the exhaust ventilation that is part of the dynamometer inside the local motorcycle performance shop. Their's has a hugely larger draw and it doesn't seem to effect anything. The 4" flex duct is quite a bit larger than the exhaust pipes and that squirrel cage realy does move a huge amount of air... but it is enough to move the exhaust to the outside of the building.
