BLDC MOTOR DIRECT DRIVEN AXIAL FLOW TYPE 14'' ROOF MOUNT SOLAR AIR VENT FAN

We are 100% Reliable Solar Powered Ventilation Fan Manufacturer, Look High into the Product Qualities & Utilities!

Solar Attic Fan Part:

* Unique Brushless DC Motor

- High Efficiency + Unique Waterproof

* Patented Ventilation Structure

- Wind Guide Baldes + Fan Blades

* Reliable Product Performance

* Easy Installation

* Standardized Production

* High Consistency

* Unique Brushless DC Motor

Our Solar Attic Fan Roof Air Fan will start and keep running once sunlight is available, own to it is equipped with a best motor. This engine is IP68 waterproof, to assure the fan be suitable to install anywhere!

High Efficiency + Unique Waterproof

* The high energy efficiency feature in our motor supports the fan start running once solar panel input reaches 9V in the morning, and it keeps running until solar panel output drops down to 9V in the afternoon!
* Since IP68 waterproof, our fan is guaranteed to work well in a long run, even in those special environments like greenhouse / water tanks, etc., while other similar items can not do!

* Patented Ventilation Structure
 

This solar attic fan is an axial flow type roof ventilator, but it is made with a 360-degree swirl turbine air ventilation structure to guarantee no backward air flow from the exterior. This is essential & beneficial!

Wind Guide Baldes + Fan Blades

* The wind guide cone with 24pcs wind guide blade structure is held a patent by us, to effectively support the interior hot air be extracted out and no any counterforce to reduce the fan efficiency!
* The axial flow type 7pcs fan blade structure is uniquely made from nylon-fiber-aluminum, to upgrade the fan system with better performance and in quieter operation!

* Reliable Product Performance at Easy Installation!

Being a self-contained solar ventilation roof fan, our equipment will work friendly & reliably after you put it onto the building roof. Moreover, own to good product structure and off-grid solar feature, our solar vent would effectively reduce the possible maintenance trouble for you in future.
 

Many Practical Product Applications from Our Solar Attic Roof Vent:

* Standardized Production with High Consistency!

Our solar fan productions run on a well scheduled line, with each fan part be tested before assembly & the fully assembled unit be further 100% tested before package. This standardized production guideline brings our products a high consistency!

THIS SOLAR FAN CAN RUN SMARTLY NONSTOP ALSO AT NIGHT!

Dual Power Supplier Part:

The fan motor engine is connected with solar panel & AC/DC adapter, 2 circuits, and it will run immediately once sunlight is available. Magically, as long as sunlight is sufficient there, AC/DC adapter will not supply power, which means AC/DC adapter will not consume grid electricity when solar panel is working!

day: by 60W/24V mono solar panel

* integrated-assemble on the fan cover, receives sunshine to power motor directly when sunlight is available

night: by 18V/21V 1.5A AC/DC adapter
* plug to a wall socket by 3m cable, through connection with grid circuit to serve as energy backup when sunlight is unavailable

An inbuilt Smart Power Controller ensures 24 hours nonstop cooperating in a best way!

if solar panel is supplying direct power at X%,
AC/DC adapter will be at (100-X)%

- you don't need to do any manual shifting operation
- you don't need to worry about any unnecessary energy consumption
