    Ah, if you're getting gravel into your vent fan you need to pick it up, its fallen over.

    Seriously, there are also glass bladed fans out there, all of ours are metal or glass, but I've never gotten anything into the blades.

    If for some god forsaken reason you are running a fan in such an eviroment you need to shut down! In addition to being bad for the fan its not good for the building or people down range of the fan to be pelted by gravel traveling at 100mph!

    We only use Aluminum blades on our fans, and, I have to admit, I've never seen a wood bladed fan for emergency operations.Our fan list is:

    Fire Engine, 1 16" square, electric

    Rescue Engine, 2 16" square, electric

    Heavy Rescue, 2 16" square, electric, 2 16" round, gas

    Tower Ladder, 2 16" square, electric, 2 16, round, gas

    I'd like to replace the gas fans ASAP with electric. Stay Safe....

    We purchased our first gas powered fan three years ago, and went through the same discussion. In the end we purchased a model with a wooden blade with black rubber protective coating.

    Never had a problem, and it has picked up and tossed a few stones in it's day. You don't do it intentionally, but if it is placed on a gravel walkway at the main door, sometimes stones get kicked up behind it.
