The 21 Inch Green Roof Ventilation Fan in Aluminum from Lijan Greentech is a practical and energy-efficient solution for improving ventilation in buildings. Designed as a wind-driven roof ventilator, the fan uses naturally occurring wind movement to help extract hot and stagnant air from the interior or roof space and release it outside.

Heat can accumulate beneath metal roofs and in enclosed industrial or commercial spaces, particularly in warm climates. Effective roof ventilation helps move this trapped hot air out of the building and encourages better natural air circulation. The 21 inch roof ventilator is designed to support this ventilation process without depending on electrical power.

Manufactured using aluminum, the ventilation fan combines a lightweight structure with durability for roof-mounted applications. Aluminum is well suited for outdoor environments and helps provide a practical solution for continuous roof ventilation.

The Green Roof Ventilation Fan can be used across a wide range of applications, including industrial buildings, factories, warehouses, workshops, commercial buildings, kitchens, and residential properties. It is particularly useful in spaces where heat, humidity, fumes, or stagnant air can accumulate.

Unlike electrically powered exhaust fans, a wind-powered roof ventilator operates through natural wind movement, helping provide ventilation without adding electricity consumption. This makes it a suitable component for energy-efficient building ventilation and sustainable building solutions.

Lijan Greentech provides roof ventilation solutions designed to complement its wider range of energy-saving products, including thermal insulation and daylighting solutions. The company specializes in ventilation, thermal insulation, and energy-efficient solutions for industrial, commercial, and residential applications.
