I don't remember whether it rained the two years I had the vent, but it overlaps the hole in the roof so as to present a minimal problem. Also the fit it tight and I do not seal it. Btw, the RV fan is about 750 cfm on high speed, using about the same power as the swamp cooler fan. I think I have a "Fan-tastic" fan.
I have given up on filters. The first couple of years on playa with the hexayurt I had furnace filters in many places. They are now all gone. I effectively have one filter now, the porous thing in the TurboKool swamp cooler against which the water is thrown by the fan/pump. It gets dirty after a week, but most of the dust sinks down to the bottom of the shallow reservoir from which the water is pumped - in other words it's nearly self-cleaning.

I like the idea of having a vent in the roof that opens or closes with a hand crank. Have you had any issues with water leakage in yours (or has water even been tested with yours)? Also do you put any filters on it as well so when it is open your not letting dust in? Perhaps with just the pressure like your saying, air / dust wouldn't come in there anyway so this wouldn't be a problem? I'm more curious on the water sealing of it, as I want to be prepared for rain :). Any recommendations on cheaper RV exhaust units that have airflow up to 500-900CFM? (As this is probably what I'll be cranking with the Endless Breeze I'm using with my swamp cooler). I was looking through Amazon but wondering if you had any you prefer. -- You received this message because you are subscribed to the Google Groups "hexayurt" group.
