Our patent-designed wind guide cone with 24pcs turbine wind gride blades structure is adopted in this ventilatior. Followiing a 360-degree swirl ventilation mode and being free from outside airstream interferes,it can work efficiently in sunny days to exhaust out the indoor heat &smell and not let any exterior air going in, so as to keep the living &working environment always clean& fresh. In raining windy days , this air draft design can also efficiently prevent the rains or winds from flowing backwardd.
To assist our solar exhaust fans be working excellent also in special environments like greenhouse / water tank where its surrounding is very humid, we've self-developed a brushless dc motor that is IP68 waterproof, and its quality can be guaranteed even by dipping it into water for tests!
1)Attaching thermostat to have the fan work/stop at preset temperature.
if 25 Celsius, on: 25ºC +/- 3ºC; off: 18ºC +/- 5ºC,
if 28 Celsius, on: 28ºC +/- 3ºC; off: 21ºC +/- 5ºC
2)Using power cord switch to control solar fan works / stops manually at any time.
3)Adopting AC/DC power adapter to support the fan runs nonstop in sunless periods under grid supply,an inbuilt Controller will smartly take care of power switch between solar panel & grid electricity
4)Utilizing solar battery system to support the fan runs nonstop in sunless periods under battery supply
