Solar Powered Roof Fan Ventilator, 200mm Low Profile Exhaust Fan for Greenhouse Shed RV Boat, Ultra Quiet DC Motor Ventilation System

Features:Solar Powered Warm Air Extractor FanOur new for Ultra low profile aerodynamic extraction unit is for Ultra quiet, and extract 950cu.ft per hourFeaturing a large efficient solar panel that does not need intense direct sunlight to operate.200 mm Diameter, and ONLY 25 mm HIGH - for Ultra LOW PROFILE extrusionSimple to fit - Just cut an 82mm and above hole , place the vent body into the hole and then tighten inside by hand with the large plastic nut. Its that easy.No nuts, bolts, or drilling required.for Ultra low no noise, simple installation.When exposed to decent levels of sunlight, the vent will turn on within 20 seconds and start extracting warm air automatically.When clouds come over on a sunny day, the vent has in built capacitors that will store charge for a short while if it needs to compensate, and will adjust the fan speed to a slower speed if required until full sunlight resumes.On overcast Spring / Summer days the vent will work intermittently, for example 20 seconds on, 20 seconds on (to charge)May not work in light due to low lux levels.Suitable for any application, garden sheds, greenhouses, toilets, roofs, gable, campers, caravans and wall or roof mounting.Specifications:Solar Panel: polycrystalline 5.5V, 2.5W DC Fan: 5V 2W RPM: 2500 RPM Airflow: 33 CFM Motor Type: DC Ball Bearing Noise Static Pressure: 27 dhPackage Contents:1*Solar Fan
