AIR CLEANER

This is an inexpensive unit to build and does a good job picking up dust especially sanding dust.
I used 3/4 plywood to build the box and 3/4 oak for the door
I used a felt weather stripping on the door provides an airtight seal
The unit has two filters. The primary filter is a 14×20 furnace filter.
The secondary filter is a “K&N Performance Filter” #33-2035, made for a Corvette,
and can be bought at most auto parts stores.
This one I wash out a few times a year.
I just spray it with any household cleaner like Fantastic and rinse with water
The three-foot long duct on the discharge moves the clean air away from the unit
so as not to pull the same air into it repeatedly, like the store bought cleaners

Very slick.
Very nice looking.
Very resourceful, in parts selection.

I’ve had lots of K&N’s. Good product.

Looks like a small block filter, right ? Maybe 427cid, but NOT a 454 ;-)

Do you know the HP and or the CFM of the motor you used ?

Absolutely ingenious, I love the exhaust duct and incorporating the car parts.

MikeDe,
Very nice unit.
I’m in the process of designing/setting up my shop (tool/machine placement, DC ducting, lighting/electical). All this includes building my own air cleaner. Seeing your work inspires me to attempt to build one of nearly equivalent quality, not just a “functional” unit. Thanks for sharing your project.

I love the idea of using the duct to keep from recycling the same air time after time. I’ll bet most of us are filing this under “Why didn’t I think of that?”

Thanks for sharing

”so as not to pull the same air into it repeatedly, like the store bought cleaners”
Nice idea , but my air cleaners are three feet long and suck the dust in one end and exhaust the filtered air out the other end , and they’re store bought and it’s virtually impossible to recirculate the same air with the velocity created by them.
I’ve yet to see any “store bought” units that are built square in the first place , and / or exhaust anywhere near the intake area.
Yours looks like a nice unit for being homemade …what fan and motor are you using in it ? : )

-- I'm absolutely positive that I couldn't be more uncertain!

Nice design and looks fairly easy to do. Could you add some info on the fan/blower unit?
