What is a Plug Fan?

A plug fan, also known as an open impeller centrifugal fan, is a specially designed fan similar to a centrifugal fan but without a scroll casing. With this design, it is typically used to push or pull air through a wall, ceiling, or window. It improves air circulation and helps cool and clean indoor air in buildings or construction projects.

Plug fans are commonly used in factories, production workshops, stores, offices, bathrooms, and other areas that require air circulation.

Below is the catalogue for the plug fan, which you can download as a PDF for convenient specification selection. In addition, we can manufacture and supply products according to customers’ specific requirements.

General Specifications

For this wall-mounted ventilation type, the performance is quite similar to that of a centrifugal fan, thus the airflow and pressure it generates are relatively high compared to axial fans of the same size.

Main product specifications:

• Airflow up to 17,000 m³/h
• Voltage: 220–400V, frequency 50/60Hz
• Casing and impeller materials: aluminum alloy, stainless steel (optional)
• Operating temperature: -25°C to 50°C
• Impeller operates on the centrifugal principle with backward-curved blades
• Dust and water resistance level: IP54
• Supports both AC and EC power supply (EC models allow speed control)

Advantages of Plug Fans

• Cost-effective: Plug fans are much cheaper than many other ventilation systems.
• Space-saving: They save space and do not require floor area.
• Compact and easy to install: Small, lightweight design for easy installation.
• Safety features: Designed for safety and to prevent ventilation failures.
• Minimal impact on indoor air: Effectively prevents pollution and removes odors without adversely affecting indoor air quality.
• Low noise: Operates quietly, ensuring comfort for households or workers in the same space.

Applications of Plug Fans

Plug fans have many applications in architectural and construction projects, such as:

• Ventilation and cooling for factories, warehouses, homes, offices, supermarkets, etc.
• Cleaning air by extracting dust, toxic gases, and ventilating to the outside environment.
• Creating suitable climate conditions for production to improve product quality.
• Providing comfort in living and working spaces by reducing temperature and humidity in summer, and limiting bacterial growth in winter.
• Using in cold storage facilities to maintain product temperature.

Depending on the purpose and area, it is important to choose a plug fan with the appropriate capacity to achieve the best performance.

Where Are Plug Fans Installed?

Plug fans are used in various applications such as in households, offices, and restaurants. Some specific installation examples include:

• On high ceilings in high-rise buildings, apartments, kitchens, and bathrooms
• On windows or walls in livestock farms
• In warehouses, factories, and office spaces

Notes When Choosing a Plug Fan

• Power: Make sure to choose a fan with the right capacity to meet the ventilation needs of the intended space. The fan’s power directly affects its ability to deliver strong airflow.

• Size: Consider the fan size in relation to the wall installation space. Ensure the fan is not too large to avoid obstruction and unnecessary space limitations.

• Efficiency: Check the fan’s efficiency rating. Choosing a high-efficiency fan helps save energy and reduce operating costs.

• Noise Level: Consider the fan’s noise level to ensure it does not cause disturbance in the intended environment. Plug fans usually operate quietly, especially in residential or office applications.

• Control Features: Check for control features such as adjustable speed, cooling modes, automatic operation, and timers. These features increase flexibility and convenience in use.

• Durability and Reliability: Evaluate the brand and quality of the fan from the manufacturer to ensure durability and reliability during operation. This helps prevent technical issues and reduces maintenance frequency.

• Compliance: Ensure the fan complies with safety regulations and performance standards. Choose fans with proper certifications and ratings to guarantee quality and safety in use.
