Can anybody recommend a ~ 18" wallmounted fan, preferably oscillating, that can take extreme wet conditions? I've been using "heavy duty" fans from the depot, but they are crapping out too fast in my conditions. I try to lube 'em on a regular basis, but one of my newest ones caught fire today. Luckily, I was close enough to hear it pop; otherwise, I may well have lost my roof. Scary stuff.
