Why does my house smell musty when it hasn't rained?
Often the damp isn't coming from the sky. It's under your floor, where the air sits still and the moisture has nowhere to go.
The Solar Whiz SW 2100 subfloor fan runs off a 40 W solar panel and moves 2,100 mÂł/h. It starts when the sun comes up and stops when it goes down. No switch, no timer, no mains power.
Send Solair a photo of your subfloor, a floor plan or a rough description. You get a specification back, not a sales call.
