fanVflo in bus

i currently have fans boosting airflo in the front of my bus in the tinware, but was talking to Kruizinkombi and he recommended setting up panels to flo-thru into door armrests and to back. didnt realise til afterward that fans are in panel that i would have to change therefore fans would be useless or armrests would be useless when fans on.
any ideas?

Huh?:o

Put the armrests on, but block them at the back edge. Cut holes and fit the vents wherever they will be the most use to you. You'll need the fans in the dash, and the microbus duct-ends so that the air goes into the armrests. It then has nowhere to go except out through your new vents. :thumb
