If DIY is your thing I've no sites to recommened. Personaly I don't

What humidity level would you aim for, Dan?

I'd have to play with that; 40 to 50% rings a bell as being normal.
Off hand I'd say as high as is comfortable.
BTW, I'm quite sure low humidity contributes to high heating costs.
I never hear it mentioned when the news is about keeping the heat
bill down in winter.
I'm going to take myself seriously and check out those scrubbers
more thourghly. I've wood working equipment, etc, and some DIY
know-how. Dan

Thread thiefs got away with my thread. It is obvious to me that they
did not read any of the information at www.safelab.com.


Dan,

It would appear that you are directing this comment to me. Sorry if I have
offended you with bad news.

Yes, I have seen the Safelab site. Their clientele are not the hobbyist,
nor even photo minilabs. They serve industrial laboratories. It would
appear that all of their work is on custom installations. That is not cheap.

FYI I have 37 years of industrial experience as a licensed professional
engineer and have some understanding of the reasons for using a scrubber.
You use a scrubber when the EPA or state environmental quality people object
to a situation such as 1/2 ton of hydrochloric acid fumes being exhausted
each day. You go to Safelab when you stand to lose millions of dollars if
you are shut down or fined. You usually need skilled trades to maintain
scrubbers and technicians to test their operation. Only a hugh commercial
darkroom like Qualex would ever need a scrubber.

If you are still unconvinced, then check out the photo minilabs around you.
They would surely scrub the exhaust if photo quality or regularions called
for it. Ask if they are even required to scrub the exhaust air. They may
not even know what you are talking about. I just spoke with the minilab
operator at my camera store. They are a professional quality lab, and the
operator used to sell minilabs. They have no scrubber on their equipment
and know of no EPA regulation requiring it.

I sincerely think that you are off on a wild goose chase here.

I'm reminded of the Japanese animated series "The Adventures of
Robotech" A race of giant humanoids called the the Centrani were part
of the mix of characters. They were of huge proportions. I think
you have spent too much time in their world. Dan
