Exhaust Fan

[Pansy-Paws]

Jason,

I'd suggest looking at a hydroponics supply store for an axial fan like that shown in the link.

Interesting that it's a local store that popped up in my Google search ... we obviously have a lot of demand for hydroponics equipment. Especially cash sales I understand
