The blower motor and HEPA filter arrived so it allowed me to begin making the temporary flow hood. I decided on a Tjernlund M-6 Inline Duct Booster Fan (460 CFM, 6" diameter) because I can repurpose it after setting up the clean room and full-size laminar flow bench. It will be used to circulate air through the GAHT pipes already buried next to the Aqua house. The temporary hood construction is simply painted plywood and a frame.

The HEPA filter is a 2' x2' x 1' standard size filter although I bought a "V" configuration for higher air flow since I wasn't sure about the capacity of the blower motor under pressure. I'm completing the front extension (actual work area) tomorrow, I hope.
