vertically mounted fan with rain cover--is it a good idea?

A carpenter friend of mine has a cargo van he works out of. He was talking about how hot it gets in the summer, and I suggested a MaxxFan, with the rain cover built in. He is reluctant to put one in the roof, with concerns about leaks onto expensive lumber. (I told him no need to worry, but I see his point.)

Would it be feasible to mount a Maxxfan vertically in an upper rear corner, where it could pull some air flow through a front window or side door?
  • Another option: Mount a 120mm computer fan toward the top of the van's wall. Cover the exterior with a "dryer vent" that is self-closing. Get fancy and install a switch on the (+) phase of fan wiring.
  • Another option is a Turbo Maxx.

    I have one. It mounts to the existing roof hatch and rests on a foam gasket between the roof and housing. The hatch can be left open and the fan thermostat set for auto run and shut off. Mine is over the bathroom and rain has never gotten even during severe thunderstorms. I do close it during tropical storms and near miss hurricanes.
  • Thanks for the comments, I will pass the info along to my friend & suggest that he contact Airxcel re warranty coverage in that installation.
  • Probablly not, use the fan one summer and then take the four scews that hold the fan motor off rotate the fan 180 and instal back, this will give the motor bearings some more life, squirrel cage fans run horizontal and do not have problems so this one should be good.

    If the work trailer has a generator I would use a small atic fan, they are mounted on a wall and install a normal RV vent also on the wall.

  • Yes you can install the fan on the wall with the max-air cover facing down so that the vent is pointing down also, make shure that there is a rain gutter above the fan just in case.
