The Latin American Suck Box.
Allegedly, it’s taken the lives of dozens of innocents.
In this case it’s being accused of things that are FAR less loathsome and macabre.
It’s a roll-about air cleaner.
Okay, so …. CraigsList had an ad for a explosion-proof fan [see SPECS, below] for sale.
It goes for $700, new
So … I picked up a couple sheets of 3/4” ply, used a bunch of scrap, bought two 3M Filtrete Furnace Filters, grabbed one of my “used” 5” pleated media filters, and …. got busy.
12-1/2” hole cut with the jigsaw. Got lucky, first time. All the joinery is “glueing blocks—” the vertical and horizontal 30×30” pieces of ply are screwed into common blocks at the joint corner—about 2×2x18” long. No glue was harmed in the making of this film.
The fan frame (16×16”) is screwed into 4×1x20” cleats, on the back of the front panel. It’s rock solid.
There’s a center divider panel, on the interior, made of 1/8” ply. It slips into blocks arranged as upper and lower guide tracks. In the ply, I cut a 19×23” opening. That’s the way the air is forced through the filters, and outward from the fan.
In the forward (fan) compartment, I have a couple sheets of Prodex foil-backed reflective insulation, for a modicum of sound dampening.
There’s a shelf in the rear (visible in the pics) that elevates the filters to … nearly central to the box. I actually do NOT need the filter access door, so … while cute … it’s inoperative. I cut the rear opening large enough to simply change the filters through it.
Suction keeps the filters securely in place.
I bought a 15’ appliance (14/3) extension cord, simply hacked off the female end, and used the remainder AS my power cord. I’ll splice the switch into that cord … when I get to it ;-)
This thing is rather rough, but … the Suck Box is known for its stealth, and its effectiveness, NOT its elegant good looks.
The last step—I jumped ahead, out of a desire to see it work—is to wire in the switch—a 12-hour timer switch. Maybe later this week. For now, straight electrical cord.
I’m doing what I can to keep the shop a little cleaner, my sino-pulmonary system … free from dust bunnies, and the upstairs (basement shop) looking noticeably different from my wood shop.
It seems to work … beautifully, and … I’m not sure, but … it MAY be quieter than my joist-mounted JDS filter, even when the JDS is on low.
So … the dust can run, but … it cannot hide. NO PLACE is safe … from the legendary CHUPACAJA !!!!
