Setting up a flowhood inside a greenhouse
    #23461137 - 07/20/16 10:56 PM (7 years, 6 months ago)

I have a laminar flowhood that I got from a science department. It's a big beast, and consequently the only place I can set it up is out in my steel shed. This shed/garage is pretty big (70ft x 100ft), and is also super dusty and real dirty. 

So I was thinking of buying a plastic walk-in greenhouse, and putting my flowhood inside it. I'd also cut a hole in the greenhouse wall and put a furnace filter over it so not too much dust is pulled in while the flowhood is operating. My thinking is that at least the air inside the greenhouse would be a bit cleaner than the surrounding garage air. Would also give me a small area I could use some lysol or oust on.

Has anyone done this, or does it seem pointless? :confused2:

Thanks, saintpedro

Dusty doesn't matter much as long as there are no strong draughts in the shed. Instead of spending a bunch of cash on a greenhouse, why not just buy that thick plastic sheeting used for construction sites? You can close off a corner with it to isolate yourself from the wind currents in your shed. Your hood will be blowing a wall of sterile air so as long as there isn't strong enough wind currents to disrupt your laminar flow, the room being dusty will not effect your contam rate.

The dust will effect the working life of your filter though, the more shit it has to clean, the faster it will end up getting clogged. Make sure to change the prefilter often as well, they usually recommend changing it every 6 months so maybe change it every 3? I don't really know how dusty your shed is so I'm just throwing a random number. You could visually inspect your prefilter once in a while to see if it's getting dirty, once you start noticing it turning grey, change it.

As long as there are no drafts. Still air you should be fine. I've set up my hood in a tent, an old barn. Didn't work out because there were drafts. I thought they were minimal enough but nah.

Thanks for the replies guys. Yeah, it's pretty draughty in there so I'll go with closing off a corner for the flowhood. :cheers:
