In a previous blog entry, I started to document the building of my ambient air cleaner. I didn’t do a blog on it’s completion and the WW gods spited me for it…..
I initially installed 2 pre-filters (intake side) and a third MERV 12 filter on the exhaust side. After building the air cleaner, I learned that this arrangement is not recommended. I found out why! It seams that the filter, placed after the squirrel cage blower, puts back pressure on the fan and causes the motor to run hot. So hot that there was a burning ordor. Unplug, investigate, MODIFY.
Here are pictures of the mod…..
In order to relocate the 4” MERV 12 filter (behind the first two & deeper within the intake) I first had to remove the cleats that held the two pre-filters.
You can just make out where the cleats were and the new cleats for the 4” MERV 12 filter:
Ramming speed; Filter install:
4” Filter installed:
In order to install & change out the 4” filter, I needed to make a “Removable Filter Cartridge” for the two Pre-Filters:
1” Merv 9 Pre-Filter, in the cartridge:
1” Generic Pre-Filter, in the cartridge:
“Cartridge” going deep:
4” Merv filter & the “Cartridge” with 2 Pre-Filters installed:
My ambient air cleaner is back, up & running….
I can now breathe much easier, both literally & figuratively!!!

The building of a “Super Sled” for my TS.
Well, that’s the plan at least!!!

Can you hold your breath a little longer while we test to see if it’s safe? This shouldn’t take more than a couple of hours…..

You live and learn Randy. Glad you were in there to smell the odor. Good call and great fix.

Dave,
I have it on a timer, so I can continue to filter the air after I leave. I easily could have been out of the shop and not caught it. I don’t think the landlord or my housemate would have appreciated that!!!

Jeff,
That is quite the deal!
Dave,
YES, but you have to move the forge inside, or get a really HUGE blower!!!

Randy – how come you didn’t post all the pics of the air cleaner? I saw some more pics you posted here. That seems like a pretty cool design…..you would be pulling the dust directly from the sanding table which is probably the dusty spot in the shop…..right?
If you build another one in the ceiling, I would leave this alone….looks well engineered man…...

Jeff,
That was someone’s project post, not about my air cleaner. I only posted to show my solution to low ceilings & show the squirrel cage blower.
I’m going to see if my “closet” unit performs well or not. If it doesn’t, then I’ll go through the effort of the ceiling duct. Having dual units may just be the way to go, though!!! Time will tell.
