Characteristics: It can be used for workshops, storages and various kinds of attics to ventilate, to change and dry air.

The system is solar-powered.

It is no need to connect the mains supply.

It works with low DC voltage, safe and reliable.

Automatically control the air quantity according to the intensity of the sun, the stronger the sunlight is, the more powerful the wind blows, up to 750m3/h.

Intelligent temperature control without manual operation.

It starts working when temperature is above 77℉ and stops below 73.4℉.

High-quality solar panel, heat resisting, high pressure resistant, stable, and long service life.

Sealed shell design.

Anti-UV material is added in the outside shell.

Perfect weather fastness, durable.

Multiple protective devices, waterproof, insect prevention, rat proof and sundries proof.

temperature controlling: When the attic’s temperature is equal to or higher than 77℉-84℉, it will automatically switch on the fan.

Back-up power (optional): cloudy or after sunset, it will switch to backup power supply automatically.

The solar attic fan continues to work making your attic temperature fall, so it will clean the stagnant air in your house to build a cool and refreshing summer night.

The professional solar attic fan can continue to run at night.

Protecting net: stainless steel screen prevents fragments, insects, birds and small rodents from accessing the device.

It allows air to circulate freely.

The solar attic fan we produce including various types, such as 20W, 15W solar attic fans, 20W solar indoor ceiling fan.

And shell case contains ABS or metal material, we would be glad to provide other details if you like.
