TOMECO Roof Exhaust Fans are a widely used type of industrial fan today, especially in areas where conventional fans cannot meet requirements, such as rooftops. So, what are the features and benefits of roof exhaust fans?
What is a Roof Exhaust Fan?
In factories or industrial facilities, workspaces are often enclosed, with significant emissions. Standard fans cannot be used effectively on metal roofs. A roof exhaust fan is designed to remove hot, polluted, and harmful air from indoor spaces with poor natural ventilation, hot and stuffy environments, pushing it outside and bringing fresh, cool air back into the space. These fans come in various models and designs.
How TOMECO Roof Exhaust Fans Work
Roof exhaust fans are specialized fans installed on the roof. They remove accumulated hot air from the top of the building to ventilate factories, warehouses, and machine rooms. A roof exhaust fan system typically includes the fan, air ducts, air inlets, opening/closing valves, sensors, power supply, and control units.
There are mainly two types:
+ The first type is Axial Roof Exhaust Fans – high airflow, low pressure, suitable for general ventilation purposes.
+ The second type is the Centrifugal Roof Exhaust Fan, which has higher pressure and is used for areas requiring stronger suction but with limited airflow. It operates quietly and efficiently.
Role of Roof Exhaust Fans
- In factories and industrial plants such as metallurgy, textile, and mechanical workshops, where high temperatures, dust, and air pollution are common, roof exhaust fans help ventilate the space effectively. They remove toxic gases and emissions while also expelling hot air accumulated under the roof, providing better ventilation and cooling.
- The roof exhaust fan system is designed and installed at optimal locations to ensure efficient operation and energy savings compared to conventional cooling fans.
- Roof positions are often unsuitable for standard ventilation fans, making roof exhaust fans particularly effective in their role.
- The rain guard cone of the roof fan is optimally designed to minimize rainwater contact with the motor, ensuring 24/7 operation under harsh weather conditions.
- The fan motor is specially selected for vertical operation, ensuring long service life and optimal performance.
- The fan is made from high-quality, durable, and aesthetically pleasing materials, which help reduce costs and provide long-lasting use.

Operating Principle of Roof Exhaust Fans
This type of fan is used to remove hot air from the roofs of factories, warehouses, and other industrial buildings, serving ventilation, cooling, and heat reduction purposes. The fan has the following key components:
- Fan Housing: Made from materials such as standard steel, stainless steel (INOX), galvanized steel, plastic, or composite, depending on the usage requirements and environment.
- Rain Guard Cone: Cone-shaped, made from SS400 steel or stainless steel 304, based on customer requirements.
- Roof Mounting Base: Square-shaped, ensuring stability and rigidity, made from materials similar to the fan housing.
- Technical Specifications:
- Airflow: 1,000 – 50,000 m³/h
- Static Pressure: 50 – 500 Pa
- Power: 0.18 – 15 kW
- Voltage: Single-phase 220V / Three-phase 380V, 50Hz
- Temperature Resistance: 250 – 400°C for up to 2 hours
The fan is manufactured from highly durable materials, resistant to harsh working conditions, long-lasting, and low-maintenance. It is ideal for dusty environments and can operate at maximum capacity consistently. The entire fan is powder-coated to protect against environmental effects, extending its service life.
Installation of Roof Exhaust Fans
Installing roof exhaust fans on the roof is the most effective way to remove hot and polluted air from buildings such as high-rise buildings, factories, production facilities, and workshops. To ensure proper installation, the following technical steps should be considered:
Determine the Installation Location:
If your roof structure is sturdy, this type of roof exhaust fan can be installed. This is the most effective solution because hot air naturally rises to the highest point of the structure.
Installation Steps:
– Mounting the Fan: Secure the fan support frame to the roof using strong bolts, ensuring the fan does not vibrate or tilt during operation.
– Pre-Power Check: Before powering the fan, inspect the fan blades to ensure there are no collisions and that they are properly balanced.
– Motor Cover Check: Replace the motor cover and verify that all fasteners are tightly secured.
Electrical Safety: Before connecting the power supply to the fan motor, ensure that all wiring to the electrical lines has been properly disconnected.
– Power Compatibility: Verify that the electrical source is compatible with the fan’s requirements.
