Systainer air scrubber

Ha was thinking of something like that other day

Would love to see the inside, could be a fun build project

Hell use an xxl 337 and you can fit a lot of airflow in there
 
Hilti have been making something similar for quite awhile. Two different sizes, and even more expensive that this.

Some creative air outlet...

I hope this isn't an apartment, cause if it is... hose might take some water when the upstairs neighbors flush their toilet.

Also no way this would result in 450 m3/h
 
I’ve been working on designing my own (in cad) as I was unaware of this solution….. I found a YouTube video

Having read all of the info on the website and watched some product videos, I’m seriously thinking about ordering one of these - and thanks to [member=76043]bobtskutter[/member] for making me aware of it. I fit 10-15 kitchens every year, and the more ‘finished’ a project gets, the more critical dust control becomes. I can’t tell you how happy it would make me not to have to spend hours at the end of every job cleaning everywhere up. It strikes me that the key to this unit’s effectiveness is where you position it - locate it on the floor underneath where you’re drilling into a wall, locate it in front of your mitre saw, locate it at the rear of your workstation when you’re cutting tiles with a diamond blade, and so on. I can also imagine this on top of a little tower of other T-Locs, standing right next to the flexi-tub I’m using to mix 25kg bags of flooring compound or plaster. The dust generated when you tip out a full bag into a tub is gross. And then leave it running for a few hours at the end of the day, telling the customer to shut it off before they turn in for the night.

Although all of my cutting, sanding and routing equipment hooks up to a CTL26 + CT-VA-20, a lot of other daily-use tools don’t - and it’s the tail-end jobs such as cutting plinths, crowns and pelmets (all usually made from foil-wrapped or painted MDF) which always result in a brand-new kitchen whose air is filled with micro-particles which end up coating every surface, since the extractor captures most of it - but not all of it. “So do your cutting outside” I hear you say? …… it hasn’t stopped raining here for two weeks straight. This job I just finished was a nightmare - the cabinets were super-dark navy blue with a dead-flat acrylic paint finish which showed up every conceivable particle. It took forever to clean it all up at the end;

I also obviously worry that I’m breathing this junk in. Although it’s a lot of money, I’m very tempted.

That’s it, [member=76944]mcfal12[/member] - you set the precedent. Mine will be ordered at the end of this month when all my customers pay me. There’s a 30-day return guarantee, so I figure I’ve got nothing to lose and maybe a whole lot to gain. Congrats on your new purchase.

Google says this is equivalent to 265 CFM. which is at the lower end of the performance rated in the Wood magazine's review. According to its spec., the scrubber seems to be at least as noisy as a box fan (typically 55dBA at max speed).
 
If negative air pressure is the goal a simple bathroom exhaust fan in a box with flexible duct going out a window etc. would suffice, and fit in a much smaller Systainer. You only need the big expensive filtration rig if you’re recirculating the air in the room.

Fair point Chuck - but the article’s predominantly talking about larger, permanently- installed scrubbers in larger shops. The advantages of this (to me) revolve around its small size and its portability - added to the fact that kitchens and similar jobsites are much smaller spaces with a much lower air volume. A bit like a CTL-SYS - a great little small-task extractor which gets the job done, but which isn’t pretending to perform like a big shop vac.
 
I should point out that the box fan filtration system that Wood Magazine put together for its review test wasn't as efficient as it should be because it wasn't sealed on the outlet side. For best performances, the box fan and filter should be sealed or properly aligned:https://cleanaircrew.org/box-fan-filters/  (see davidelfstrom's shroud)

In terms of noise, I find that the furnace blower + filters housed in a wooden box the best (it's located just next to my table saw), while the box fan system (just the fan + a single filter (MERV 12(?) at max speed) is bearable if it's placed at least 8 feet from me.

Of course, the noise factor isn't a big deal when using a machine as I always put on hearing protection when milling or routing, etc.

Thanks Butcher- I agree it’s not the ‘best option’ and it’s certainly expensive, but I have one set of lungs and being I’m terribly allergic to dust (while it’s a ‘minor’ health affliction I’m perpetually stuffy at best) and as I was designing a Systainer solution anyway- my time is also worth a lot and in the end this will pay for itself a hundred or more times over.

I didn’t grab replacement filters, I’m hoping I don’t regret it and end up with another $100+ in shipping fees. I wanted to wait and see what size they are and if I can source a solution locally. For now I will be diligent about cleaning the prefilters often while I work out a longer term solution.

Festool MX-A #576759

I know [member=8955]Coen[/member] - I know. I’ve always looped the hose through the flexi-tub handle, then put on the wide floor nozzle which effectively does the same job as the 'proper' Festool hook-over gadget. But my backside puckers every time I do it - one of these days the nozzle’s going to fall off into a tub of sticky wet stuff  [crying]

As an aside - I emailed the company and told them about this thread. It would be kinda cool if they registered like so many other suppliers have done. And a 50% FOG discount would be just grand, thankyou.
 
I have three box fan air filtration systems (1 for the shop, 2 for the house), all used not much as they should be due to their noise (55 dB at max speed). That's all going to change, because the addition of the shroud has reduced the noise noticeably, which is also said to be improving airflow by 38 to 40% (I don't have an instrument to verify that):

Various reports have confirmed that the box fan outfits have performed even better than some of the commercial home air purifiers that sell for hundreds of dollars.

Wow, i never expected my post of that air scrubber to be so popular! :)

I really need to do something similar in my garage, the dust from my new table saw is awful.

Regards

Bob,

In North America, another common shop-made filtration system is the furnace blower version:

Quiet and powerful, but, of course, nowhere as portable as a box fan. I use two filters (one as a pre-filter) for that. When neighbors replaced their furnaces, the working blowers were ditched.
