The innovative German SME developed a solar-powered, independent and therefore mobile air ventilation system for boats, tents, caravans, mobile homes and camper vans. It is intended to be used in the wintertime or when the caravan is not in use for a longer time.
With no need to attach it to the caravan, the system is easy to assemble and fully operational upon receipt. After opening one of the skylights it can just be put up on top, without causing damage to the vehicle. It operates by siphoning fresh air, warming it up and then feeding it to the interior of the caravan.
