    Cubic Meters/Hour

    So 467 Cubic Meters is 16,345 cubic feet per hour...divide that by 60 minutes in an hour and you get about 272 cubic feet per minute...you're good in that tent.

    If you're worried, get a speed controller or the fan

    You're running about 235 cfm through your fan...

    1 m3/h = 0.5885745 CFM

    m3/h is cubic meter per hour
