ventilation installed but nothing but problems
installed my hood with the 650 cmf fan, the company supplied a ten inch flex pipe but do to my set up , i had to reduce it to 8". the pipe runs maybe 2 feet and is vented outside through a 8 in vent with baffle, this is a dead straight shot to the out side. turn on my fan, light a smoke and i watch the smoke curl up and over the hood. light a roll of paper and blow it out holding it at the torch head, the smoke comes straight back and into my face. holy smokes, should have stuck with a dust collector motor and a 6" pipe or a box fan at a window, From the moment i preassembled this unit, i had my doubts. baffle flange that one has to assemble to the unit, shows air light every where, the motor flanges are not tight(tape them?). so here i sit $400 in the hole, and what to do, SOB, really had hope this was a done deal, but now I have got to start all over and oh ya got a nice 8" hole out the side of my shop wall. Any suggestions?
