The following are several types of exhaust fans that are commonly used:
1. Axial Fan
Description: This fan has blades that rotate along the fan axis, forcing air through the blades and circulating it directly.
Usage: Ideal for applications with direct airflow and large volume requirements, such as household ventilation, light industrial spaces and kitchens.
Advantages: Efficient in flowing air over short distances, simple design, and generally more economical.
2. Centrifugal Fan (Centrifugal Fan)
Description: Uses centrifugal force to move air through ducts. Air is directed radially out from the center of the fan.
Use: Suitable for applications that require air flow through ducts or over longer distances, such as industrial ventilation systems, factories and commercial facilities.
Advantages: Can overcome higher duct resistance and is more effective in moving air over longer distances.
3. Wall Fan (Wall Fan)
Description: Installed on the wall and circulates air from one side of the wall to the other. Usually have a design that allows air to be channeled over a wider area.
Use: Ideal for ventilation of rooms with limited floor space, such as small spaces, warehouses or service rooms.
Advantages: Saves floor space and can provide effective ventilation in limited areas.
4. Ceiling Fan (Ceiling Fan)
Description: Installed on the ceiling and functions to circulate air throughout the room. It is usually equipped with blades that rotate to create an even air flow.
Use: Used in a variety of environments, from residential homes to offices and public spaces, to improve air circulation.
Advantages: Able to create even air flow throughout the room, often also equipped with additional features such as lights.
5. Box Fan
Description: A box fan with blades mounted inside a box frame. Usually installed on a window or wall for ventilation.
Usage: Ideal for large ventilation and air circulation over large areas, often used in storage rooms, garages or large work spaces.
Advantages: Can move large volumes of air with high efficiency, often has the ability to be moved easily.
6. Inline Fan (Inline Fan)
Description: This fan is installed inside the ventilation duct, with a design that allows air to flow through the fan directly without requiring an additional casing.
Use: Used in ventilation systems that require air flow through long ducts, such as HVAC systems, building ventilation, and industrial applications.
Advantages: Efficient in flowing air through the duct and can reduce noise levels compared to fans installed outside the duct.
7. Ex-proof Fan (Explosion-proof Fan)
Description: A fan specifically designed for use in environments with a risk of explosion or fire, with a casing and components that are resistant to hazardous conditions.
Uses: Used in the chemical industry, oil and gas plants, and other potentially hazardous environments.
Advantages: Guarantees operational safety in high risk environments, ensuring safe and reliable ventilation performance.
8. Ventilation Fan (Ventilation Fan)
Description: Typically includes various types of fans designed specifically for complex ventilation systems, often with the ability to connect multiple units via ducts.
Use: Used in ventilation systems of commercial buildings, large industries, and facilities with special ventilation needs.
Advantages: Allows for an integrated and efficient ventilation system setup, able to address various ventilation needs in large facilities.
