How to Use Your Mixed Flow Fan

The WhispAir Mixed Flow Fans work by moving your stale humid air out of your grow room - attach them to our WhispAir Carbon Filter and you can say goodbye to unwanted odours at the same time. Simply attach the fan to the filter using several options of different clips, couplings or clamps. Hang the fan and filter in your grow room, then attach ducting to the other end of the fan, feed the ducting through your extraction sock (ideally through the top of the grow tent) making sure to keep it as straight as you can.
