The blower draws air into the box or plenum. The air remains there and as the pressure builds it starts forcing it out through the path of the least resistance the hepa filter.That is just plain awesome microbe... I like the air flow design, air is forced from the top and mixed then evenly distributed through the filter. Is that correct? Very inspiring...
Pressure is built up evenly and allowing for the air to exit evenly and at the same rate and speed across the entire face of the filter.

I finished building Big Bertha yesterday.
She don't look pretty, but as long as she works.
All of the wood glue and silicone will fully cured today, so I have to make room for her somewhere.

Your going to love working in front of a hood. It really makes a difference as far as efficiencies are concerned. Its just a pita to work with a lot of product in a sab without having a sore back.I finished building Big Bertha yesterday.

My hood doesn't blow out the flame until it is 2" from the filter. Should I get worry about a fan speed controller to turn it down?

It shouldnt blow out the flame at all but just bend it up to a 45 degree angle. I would stack prefilters first and if you still cant dial it in, then add the speed controller.My hood doesn't blow out the flame until it is 2" from the filter.

No problem. I love DIY builds and when done correctly you could save hundreds or even thousands of dollars depending on the build.Thank you for this. Mine is nothing like yours but I was able to use this thread to build my hood. So far it's just built and flame tested but all looks right. I really appreciate you taking the time to document your builds.
I appreciate you appreciating my build!
