[Greenbuilding] controlled combustion air supply

[Stephen Collette]

Hi Ross and all,

I was wondering if you could mod up one of those dryer vent cap units, the ones with the spring loaded styrofoam ball, to work backwards, instead of exhausting? That way you have your seal when not in use, and I suspect you could tweak the spring tension to get it to what pressure you desire with some noodling. It does exactly what you need it to do. I'm just not sure if you could make it work, or if it's the most logical thing to use.

Cheers

Stephen
