  • Heating indoor air mode, can keep heating the room air, and keeps away from any wet or cold or smog air. When people at home or when in the winter morning, just open the room air inlet; when people out or at noon, close the room air inlet and introduce fresh air to ventilate and dehumidify.
    For other models or other brands, the air speed will decrease when air pressure goes up, therefore, the efficiency of heating absorption will decrease. In case you open the window or some other gap to let air go out, but meanwhile, the heat will also be lost. So internal circulation mode is the most suitable for heating room air in the winter or cloudy day.
  • Special heating absorption board: Corrugated special anodic aluminum oxide, texture nano heat insulation coating, high absorption, low reflection. Solar absorbance of selective absorbing coating: 0.92; Hemisphere emittance of selective absorbing coating: 0.12.
  • Solar photovoltaic panels are produced with well-known brand cell in high quality, high photoelectric conversion efficiency, low conversion efficiency attenuation rate, with life expectancy for 20 years. Collectors can be used to dry crops such as vegetables, fruits and grains. The service life of photovoltaic panels will not be affected even under high temperature and strong light in tropical and subtropical regions.     
  • Instead of hydraulic fan, double ball fan is adopted, with longer lifespan, low temperature resistant. SUNON from Taiwan is the most well-known fan brand in the world.
  • Under sunlight, the air inside the OS collector flows along both sides of the heat absorbing plate and can absorb the heat well from the absorbing plate. Tested in 900W / m2 sunlight, when the air volume is the same, the temperature of the OS collector is 4 ℃ higher than the collector where air flows only from one side of the heat absorbing plate.  

  • Air outlet: it can be opened and closed manually or automatically, with 5mm thermal insulation cotton inside, good insulation effect.  Automatically turns off when the fan is not running.
  • Sealing strips are with high-quality silicone rubber: anti-UV, climate-resistance, better appearance.
  • Frame: exclusively for open air, anti-UV texture coating, anti-UV outdoor screws.
  • Low iron solar tempered glass is with big intensity, high elasticity, the transmission is excellent. Lower diffuse reflection can prevent heat loss.

                                                                        OSCAR Warranty conditions  

  • SUNON fan life expectance: 70000 hours; 40000 hours warranty.  Thermostat, air outlet can be replaced free of charge within 2 years.  The lifespan for solar pv panel is 20 years, guaranteed for 10 years. While glass and aluminum materials are with long lifespan.
  • Easy installation, maintenance and operation.
    OS32, OS40/42 can be installed in 2 different directions.

  • Note that by setting up two panels, e.g. one facing east-southeast and one south-southwest, you can take full advantage of the available sunshine throughout the day.
  • Can be installed on the wall or roof without the help of electrician/ construction worker. Small area, light weight. Installing your solar panel is so easy that you can do it yourselves. Product includes thermostat and all the necessary accessories for installation, such as screws, fixing clips, air ducts, air outlets, manuals, etc. Please distinguish wooden house and brick wall, so the correct electric drill is adopted.

  • Wooden house tools:Heating indoor air mode: when people at home or in winter morning, just open the room air inlet; when people out, close the room air inlet and lead in fresh air to ventilate and dehumidify. If you want a higher heating efficiency, please turn on the air outlet to maximum, heated air losses less if air speed is higher. Please turn down the air outlet, if you need air going to the room with higher temperature. For rooms without good ventilation in winter, we need to turn down the air outlet, so the air pressure will not increase rapidly, then the heated air can be blown into the room easily.  
  • Transportation
    If just 1-5pcs samples, it will be cheapest by express to your door. If about 10pcs, we can consider air transport to airport. It usually takes 7-10 days by air to airport or by express. Sea shipping will be much cheaper for larger order quantity. It usually takes 40 days to seaport.
    Unpack the appliance and ensure that nothing is damaged and that all contents are present. If parcel arrives with serious damage, please contact express customer service before receipt, meanwhile please take pictures to retain evidence. In case of loss or damage for air delivery or sea shipment, we recommend ordering insurance. 20pcs/pallets for OS series.
