nycstev said:Great Idea . I don't think the headloss through the T is a big deal since its drawing from both sides.The filters should be the same so the drop is the same there.It max it can flow CFM wise would be the capacity of that oval tube anyways. What I would like to see however are those pipes made of some non conducting material. Maybe some thermoplastic or something because they have to heat up eventually and become little heat exchangers themselves.
I may have the metal ceramic coated..not sure..but will do some kind of insulation..
