is there amy way to measure how many cfm are actually moving through your ducting?
950 cfm carbon filter? What brand? Can filter?
I'll figure it out when I get home and get back to ya.I gotta look up all the specs and calculate it out.
So you have an intake fan too? Just an fyi unless the intake fan is the same size as the exhaust fan it's not doing anything. It's better to just have an exhaust fan pulling with a backdraft damper on the intake. If you put a small fan on the intake it just chokes the whole system down. The exhaust fan will pull whatever it's gonna pull.
Most exhaust fans do not have controls on the, you have to use a speed controller to control the speed. If the exhaust is significantly larger than the intake fan, it is making the exhaust fan work harder as the intake fan is actually impeding the inflow of air.
I'm trying to understand.. Fans have controls on them. How is a smaller fan not helping. It's lessoning the stattic pressure yes? It's a special phresh inline filter. You dound like you know what your talking about.
Passive intake is all you need. If your cooling your lights with the fan then your rooms temp is all you need to know if your cfm's are enough.
the way to measure air flow is with a hot wire anemometer. they are not cheap and honesty it will not tell you want you want to know
