Re: flow hood question [Re: Bacon18]

I'm not 100% sure on this model, but I think there should be another hose going to that second hose barb. Do you see one in there? Is the minihelic in the same chamber as the filter or is in in another area? One barb should be exposed to the plenum and the other barb should be exposed to outside the flowhood. If it is inside the part where the filter is mounted, like you can see the back of the filter where the minihelic is, then it doesn't need to have the second hose since it's already in the plenum.

the minihelic is the gauge, sorry friend :laugh:

is the back of it in the same chamber as the filter (the plenum) or is it in a separate chamber?

just so you guys know the mini helic is supposed to read 0.5 on this gauge as per the online manual. I figured out there was an air speed adjustment and bumped it up to that level.

Nice good to know. So it would be 0.5" for a new filter and 1.0" for a maximum used up filter (while the unit is making 100fpm) Make sure to buy a 0.5" w.g replacement hepa for it then. A lot are 1.0".

Hey Bacon..,
Just for giggles you can build a water gauge with silicone a plastic clear flex  tube and water. Oh a ruler to measure the rise and fall of the water column in the tube when running the filter. One end of the tube in the plenum and the other end to the outside atmosphere. Don't forget to shape the tube into a U....
