Description
Product Overview – Roof ventilators
Roof ventilators are ventilation and exhaust devices installed on building roofs. They are used to exhaust indoor heat, moisture, harmful gases, and dust through the roof to maintain fresh air and a balanced temperature. They are categorized as either natural ventilation (unpowered) or mechanical ventilation (powered) and are widely used in industrial plants, logistics warehouses, commercial buildings, and large public spaces.
Air leakage rate: not above 0.5% higher than that of the ventilator in its fully open state in summer
Minimum torque of operating device: 0.12, maximum snow load it can withstand: 50KN/m2
Why Choose Our Roof ventilators
Efficient Ventilation: Rational air duct design provides strong exhaust capacity and high ventilation efficiency, effectively reducing indoor temperature and humidity.
Energy-saving and environmentally friendly design：Non-powered models require no electricity and operate with zero energy consumption; powered models can be equipped with variable frequency energy-saving motors.
Adaptable to various roof structures：Supports installation requirements for flat roofs, pitched roofs, metal tiles, and concrete roofs, with a leak-proof design.
Customizable：Air volume, material, color, opening size, and control system can be customized to meet customer needs.
Frequently Asked Questions (FAQ)
Q1:Are roof ventilators leak-proof after installation?
A:Yes. They are designed with a rainproof structure and sealing rings to prevent water leaks and seepage even in heavy rain.
Q2: Can the ventilator's color and material be customized?
A:We offer color spraying (RAL colors) and custom materials such as stainless steel, aluminum alloy, and galvanized aluminum.
Q3:Do you provide installation services?
A: We provide installation drawings and remote technical guidance, and we also support project coordination and on-site service (depending on the region).
