Fan idea..still needs work

[cranetruck]

Thought I could make use of the fuel burning heater when it got hot outside also, as a fan, but the idea has stalled out.
This goes back a year or so and when I noticed the thread about the nifty fans earlier today, figured that it may be appropriate to mention.

The idea was to use the blower in the heater without the heater actually being turned on so it could fan the driver (and passenger) via existing duct work.

Turned out that it is not very effective and the deflector and nozzle must also be moved further down, since the home made deflector obstructs the view.

The switch box has two switches, one to disable the heater and one to turn on the fan.

Can't tell from the pic but if the heater box is located near the engine, kind of how the deuce heater is under the hood, it could just blow more hot air in the cab. Just a thought on my part.

Bob, the air comes from the outside. Note the two mushroom covers, the one on the left is for the heater.

The problem, besides the obstructed view was the amount of air flowing. Now when this project is "activated" again, I may continue to experiment...

Would something like these outlets work. Mount to the dog house and you could rotate forward to use as defrost or rotate back to direct air to the driver / codriver stations. Just a thought.

Hey Diesel Bob were did you find that ? I could use something like that for my M920.

Yeah, something like that might work, The two defroster ducts can be closed off (there is a baffle) and a new opening made in the fiberglass main duct.
The air delivery is about 130 CFM so with only one duct for the driver, at least, there may be enough.

Well, installed my original single switch control box and experimented a bit. There is actually plenty of air flow when all except one "register" is closed off.

Lowered the nozzle/deflector assys and the fan is now doing its job without taking up windshield space. Feels like the cooling effect from a small fan, except using outside air.
If not mentioned before, the exhaust from the fuel burning heater must be uncovered (I usually have it covered to keep rain out).
