Awesome thanks for the encouring advice!

I have had an answer back regarding the intake fan:

"Hi there it will push 130m'3/hr at 2800rpm"

THe exhaust fan i have is here: Amazon.com: Inline Fan TT100 4" 115CFM 2 Speed: Kitchen & Dining - the specs listed are:

115CFM 2 Speed

You have me a little concerned about the power ration between the intake and exhaust system i bought.. can you confirm with the information above that they will be sufficent and work together well?

Or do you need more info, just let me know

Thanks again!
