The old thread broke:
http://bethepro.com/forums/topic/new-bosch-vacs/I am sure there is lots more to be said about the Bosch vacs – 090a/s and 140a/s

Thanks John for catching that and opening the new thread. I am sure there will be more discussion on vacuums as OSHA starts to tighten up on air quality/dust issues.
From the ivinc.com website:
Crystalline Silica Standard
OSHA is looking to cut in half the permissible exposure limit (PEL) for crystalline silica. It contends that around 2.2 million workers are exposed to respirable crystalline silica while doing their jobs. These workers are mainly in the construction industry, but they also work in brick, concrete and pottery manufacturing, as well as operations using sand products, such as foundry work and oil and gas fracking.
OSHA wants to see the acceptable exposures reduced from around 100 micrograms of respirable crystalline silica per cubic meter of air (μg/m3), averaged over an eight-hour day, to a new PEL of 50 μg/m3. The same new PEL would apply to all industries it covers.
Read more about OSHA’s proposed rule.
At the end of the day, crystalline silica (a biproduct of sawing and drilling in concrete) is dangerous to the health of the workers on the site and the general public. If you work in concrete, make sure to follow all guidelines and wear protective gear as well as install proper dust removal apparatus to ensure a safe work environment.For more on the new rules, click here.

Nice link Jim. It was only a matter of time before OSHA started cracking down on silica PEL in the workplace. In my opinion, it probably will not be long before we see stricter PEL’s on drywall dust and sawdust.

Member since 12/07/2013I think the OSHA reality is also coming north of the border. It’s will cause some pain but I think it will benefit all. Dust of all kinds can be such an issue.
Speaking of which, I ordered up another HEPA for the vac last week.

Always willing to learn .
That was an interesting read on the proposed guidlines. It makes sence, but I’m sure there will be friction with some that don’t want to spend the money on good dust collection.
The silica dust rule will make a lot of changes and sell a lot of HEPA vacuum’s. It will add a lot of respirator certifications and dust control. I just ordered the Bosch dust collector for my rotary hammer to use on a project to control dust.

Was that to replace the one that you lost with your old vac Brad? I’ve never been able to find the filter specs for the regular filter. I would really like to know what the micron rating is.

I might not mind some more restrictions. Some times when the masons run their gas saws to cut block inside the rest of us choke on it

Yeah that’s more than a bit annoying. It’s exponentially worse indoors. I wouldn’t be surprised to see encouragement to cut with water also. The dust level is much more tolerable when cutting wet.

InstagramGwe use water whenever practicle when cutting concrete. Second choice is a vac and las is open dry cutting. I use a good mask when doing that.

Yup, to replace mine that got “lost”
I’ve never found out either. I am using the DD with mine when I use the hepa. Up next is a L4 to put it on so I can attach it to the top of the vac.

Self employed Pro since 2014!!Yep VOCs and now dust. It will be expensive to comply once dust collection becomes mandatory and will include outdoors as well as indoors.

Did you get compensated for the lost hepa filter Brad?
Do you always use the hepa or just for certain applications? Do you find any noticeable difference between it and the regular filter? I’ve been trying to decide if it’s worth it for me to get a hepa.

nope. And I just got a call from Bosch and I forgot to mention it…I’ll have to call him back.
I only use it when routering/cutting MDF and for concrete. I would use it on tile/grout as well or any time I am in a house cutting (which isn’t very often).
I am using it with the fleece bag.
I can’t tell any difference, it’s just that one’s a true HEPA and I have no idea what the other one is. The inside of my vac with the fleece or paper bag always looks clean. Like brand new clean.
Brad T
Self employed Pro since 2014!!I’m finding that the fleece bag seems to contain all the dust as well. There still isn’t any dust on the filter yet or inside the vac like you said. I’m really enjoying having the vac, it’s a game changer.

I can see it at some point. They are regulating everything else, I wonder why they have not gotten to this.
