70W solar attic fan is used for ventilation and drop temperature of buildings such as factory public halls and warehouses.
1. Product Description
Solar fan is a ventilation device that uses solar panels to convert solar energy into electrical energy and drive the motor to operate.
Solar fan can keep fresh air in the room.
Install solar fans on the roof,and keep ventilation to reduce mold growth in winter and temperature can be reduced in summer.
100% solar energy, energy saving and environmental protection, reducing electricity bills.
Solar roof fans are mainly composed of solar panels, brushless DC motors, fan blades, air ducts and bases.
Brushless DC motor, long life and low noise.
High-efficiency solar panels last up to 25 years and the frame is made of aluminum.
The support structure is made of stainless steel.
The air duct and the base are made of hot-dip galvanized steel,spraying the coated surface with epoxy resin prevents corrosion.
The temperature control sensor switch is set on the fan, and the starting temperature of the motor can be selected from 15/20/25±5°C.The temperature control switch may not be used in warm areas.
It can be equipped with an adapter to work in the absence of sunlight.
SUS304 fasteners have good corrosion resistance and long-lasting stability.
The butterfly nut design makes the roof installation easier and safer.
