Alright folks, I've been inspired to build a laminar flow hood. After years of doing TC in a ten gallon aquarium I am finally going to upgrade the facilities.
Here's what I have ordered: (All ebay)
Blower motor: http://www.ebay.com/itm/221332105204?ss ... 1423.l2649
Filter: http://www.ebay.com/itm/331105106736?ss ... 1423.l2649
Now the filter isn't designed for a laminar flow hood type application. It is a clean room air filter. So it can pass large amounts of air with a relatively low resistance. As such I will be coupling this filter with a couple of 3M filtrete allergy type filters to increase the static pressure to "laminarize" the flow. Also, in my design I am leaving about 9 inches from the back of the filter to the back of the box for plenum, just to get a large pressurized volume to help achieve laminar flow.
The box will be made out of 5/8 MDF and have 1/2 inch x 1/2 inch square polar dowels at the corners to fasten it together.
So far my rough dimensions will give me a 13" working depth, with a 24" by 24" cross section. It'll be like working in a palace compared to what I am used to. I'll post pics as things arrive and update this thread with build progress.
I am very excited about this project. Also, I wanted to dump my build progress on a non-"medicinal" mushroom forum. Since all of the really good build projects seem to be documented on legally questionable websites.
