FW: Fume Hoods suitable for glue - both brush on and spray types

Thanks everyone for your valuable input.

Since posting my query I have learnt that charcoal filters tend to attract
similar properties to itself for filtering - carbon. (A perfect application
is in submarines for clean air filtration) The problem I found was, I
couldn't find any carbon product or by-product in the glues or thinners MSDS
(Material safety data sheets) we use.

I also found out that any particle other than carbon will attach to the
charcoal and immeadiately block that area, rendering it useless as a filter.
Does that mean we need to shake the charcoal filter around a bit ? If the
particles are trapped on the carbon, I wondered if we were still exposed to
the fumes regardless

Not being a chemical engineer I cannot say for sure the charcoal filters
really work for the purpose we need them to.

Here is my original question and I would like to post a summary of the
responses


Hi everyone,
I am presently doing research on a suitable fume hood for our small glue
station to reduce health symptoms. We currently don't have one and I would
like to hear from everyone on;
what you use
do you think it is effective and if so, how do you know. (Because the
manufacturers literature says so or have external tests have been done)
If you use the charcoal filters how often do you need to change the
charcoal?

Thank you very much,

The responses were great and full of welcome advice. Many others asked for
the responses to be posted as they were also wondering.
As well, thanks to the companys who responded.

As I didn't clarify that I would post original responses I feel responsible
to only post a summary.

Overall, the opinions expressed were equal for either the ventilation
extraction system or the charcoal fume busters (Atlas seemed to be the
most used source)
The charcoal needed to be replaced 3 - 12 months depending on the company at
an ~ cost of $50 USD
No matter which one was being utilized, everyone expressed satisfaction,
fumes almost non-existent and the drying time is cut in half
It works good for small jobs It is a great system and is very efficient



My personal opinion after the little I have learnt is the ventilation
extraction system would be best, get the particles outside.

Hope this helps you all.
