Project Information

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.

Hundred bucks.

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 !!!!

Nice CL score. How is the fine dust collection with it sitting on the floor? I need one of these though it will probably go on the ceiling.

I believe that's explosion proof, not bomb proof. If it bomb proof, you could sell that to the military for big $$!

nicely done. just for heavens sake - cover that hole to the spinning metal thingy… ;)

the good thing is - in case of bombing, we know one project will survive it for sure!

Chunk: LOL ! Changed it. Thanks.

Sharon: the seller has, and-when he can-will get me the "shutters" that came with the fan:



Scott: I already have one hanging from the joists:



I'll use this at the "other end" of my shop. I figure … the fines are probably just as likely to be pulled down as pulled up, so … I'll go at 'em both ways.

Ellen: It's only fair, since … technically … I have about SIX eyes at any given time :)

Wouldn't the appropriate monster here be the Chipacaja?

As a thought - could you make the height so it could be used as a table saw out feed table when one is needed - Ive been looking to fashion as out feed table and your fan project probably will be incorporated into what I will build - thanks for inspiring my thought process !!!!!!!

Thanks Neil. Now you make me think I need 2 and I don't even have 1.

Rand:

So noted ! I'm waiting to see if it starts rolling around on its own, from the fan pushing so hard, and the box being on casters :)

1yeldud1: good thought. I did think about that, but … a) It was already getting pretty big, and b) I din't put locking casters on it. Having it move easily would be a negative for an outfeed table. I thought about a set of blocks on the outer corners of the box's top, making it easy to set a small "table" on the TOP OF the box, and matching its height to the height of my workbench, if need be.

It IS either pretty versatile, or pretty cumbersome-depending on how you look at it.

SASmith: you came to the wrong place, if you're looking for ways to SAVE money :)

Good job Neil. When you move that tank try not to scratch your new bench, :)

I was thinking (which is dangerous) on the side that you would put closest to the table saw - use 2 fixed casters. On the side away from the table saw use either 2 wood blocks or bolts to establish a level surface and to keep the "box" from shifting around on the floor. To move the fan box you would have to slightly lift the edge of the box on the side with the wooden blocks and move to its new location using the fixed rollers For the top I was also thinking of a surface that could be adjusted in height using a series of leveling bolts or a second "box" set on top of the fan to match the height of the table saw of your workbench. Just my thoughts.

Looking at your photos it looks like you have already acquired a small storage space under the fan. A great area fro items that are not affected by fine dust !!!!! Possibly a medium sized plastic sealed container from wally world would fit the space - can never have too much storage !!!!!

Fan specs: Number of Blades 4.
There are 6 blades on the photo. Is it the right fan?

Ok Neil, now you can get into spray painting in a serious way. I think that might be the real purpose for that fan. There are some good articles in FWW about how to set up a portable garage spray booth.

1yeldud:

I like where you're going with this !

I built the beast bigger than needed, and square, largely because … many people that BUY pre-built shop air filtration units … have gripes about the odd-sized filters they need to buy.

Moving the rear shelf, and replacing the 1/8" hardboard divider with one that has a different size "window" cut into it … will give me the flexibility to use pretty much any filter up to 30×30".

I'm probably more likely … in my shop … to build a fold-out outfeed stand, if anything, and … I say "if anything" because the Bosch outfeed extension do a darned good job with everything I ask … except … providing extensions for the miter slots, for things like my crosscut sled.

Mike: One other design feature I built IS the capacity to add about another 6" of filter, in the stack. From what I understand, you need a carbon or charcoal-based filter to get at odors and fumes for things like finish.

But … it's there.

In reality, though … if I build any kind of spray booth … I'm likely to take OUT that fan, and turn it into a simple exhaust fan FOR the booth. Then, with the change of one 30×30" ply panel … I can put a squirrel cage motor into THIS beast, and not miss a beat :)

Viktor: Good eye ! I'm pretty sure this fan is a couple years old. The seller provided the specs, and … I'm assuming … it was based on the equivalent NEW model. Next time I'm rooting around in the box, I'll see if I can dig up the actual model number.

But … browsing the Grainger site, for the "explosion-proof" Daytons … they pretty much all seem to be 4-blade, now.

Fernando: thanks ! I've decided that …. what these fixtures do to each other-particularly when I'm NOT there-is simply beyond my control :)
