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!!!
Next up on the “Dungeon To Lair” Metamorphosis…..
The building of a “Super Sled” for my TS.
Well, that’s the plan at least!!!
