Laminar Flow Cabinet Build

[Afid]

I recently built a laminar flow cabinet for seed flasking and I thought I would share some pictures and info on its construction. I just used it for the first time today and it seemed to work great! Long story short, I took a clean room filter (from a photography lab I think) and built a coroplast box around it with a plexiglass front. I also added a pair of furnace filters at the intake vents to block any larger stuff from getting into the more expensive filter.

I forgot to mention that there is an led light on the inside so that you can see what is going on in there as well.

The biggest issue I have found with it so far is that plastic is very prone to static electricity, resulting in every little piece of dust (and in this case hay) in the area sticking to it. To help with this I wipe it down as often as I can with Alchohol (to remove and sterilize dust) and periodically sterilize the entire room with ozone gas.

You might be able to do away with the flanges altogether. Looks good though. :

What is pushing the air through the filter into the box?

How are you able to access the interior?

Most of the silver box shown at the back is a big fan.
The plexiglass sheet across the front slides up on rails.
