Introduction
The belt-driven axial fan is a ventilation device that drives the impeller to rotate through the motor to achieve the axial flow of air.
Features
Strong Speed Regulation Flexibility
The axial flow fan adopts a pulley transmission structure, and the fan speed can be adjusted steplessly by changing the pulley diameter or configuring a variable frequency motor to adapt to different ventilation needs.
Low Noise
The belt is a flexible transmission component that can effectively absorb the impact between the motor and the impeller, reduce the vibration amplitude by 20%-30%, and reduce the noise by 3-5 dB, thereby improving the comfort of the use environment.
Good Overload Protection
The belt drive has a natural slip function. When the fan is overloaded or the impeller is stuck, it can avoid damage to the motor or bearing, reduce the failure rate of the belt-driven axial fan, and ensure production continuity.
Applications
Industrial Plant Ventilation
Used for high-volume ventilation and cooling systems in workshops such as metallurgy, chemical industry, and machinery.
Building HVAC System
Widely used in ventilation and ventilation places such as shopping malls, warehouses, and basements.
Agricultural Breeding Ventilation
Used to improve air circulation and reduce ammonia concentration in scenes such as chicken houses and pig houses.
Cooling and Heat Removal System
Suitable for high-temperature environments such as power and boiler rooms that require rapid heat removal.
Firefighting and Smoke Exhaust Assistance
Used to assist smoke exhaust systems in places where large air volume is required but high pressure is not required.
Air Conditioning Equipment Matching
Belt-driven axial flow fans are often used as matching fans in equipment such as air handling units and fresh air units.

FAQ
Q: How does a belt-driven axial fan work?
A: The motor drives a belt, which rotates a pulley connected to the fan shaft. This indirect connection allows for adjustable fan speeds while keeping the motor separate from the airflow, reducing heat exposure and increasing efficiency.
Q: What are the main applications of belt-driven axial fans?
A: They are used in HVAC systems, cooling towers, industrial ventilation, agricultural facilities, tunnels, and exhaust systems to move large volumes of air efficiently.
Q: How does a belt-driven axial fan compare to a direct-drive axial fan?
A: Belt-driven fans allow speed adjustments and have longer motor life, but require more maintenance.
Q: What maintenance is required for belt-driven axial fans?
A: Regular maintenance includes belt inspection and replacement, pulley alignment checks, lubrication of bearings, and cleaning to prevent dust buildup.
Q: What materials are used in belt-driven axial fans?
A: Common materials include aluminum, stainless steel, galvanized steel, and fiberglass, depending on the application's durability, corrosion resistance, and airflow requirements.
Q: Why are belt-driven axial fans preferred in cooling towers?
A: They offer high airflow efficiency, adjustable speed control, and motor heat protection, making them ideal for dissipating heat in industrial cooling processes.
Q: Can the speed of a belt-driven axial fan be controlled?
A: Yes, speed can be controlled by changing the belt or pulley size, allowing users to optimize airflow for different applications without using a variable-speed motor.
Q: What are the common issues with belt-driven axial fans?
A: Common issues include belt wear and slippage, misalignment of pulleys, bearing wear, and reduced efficiency due to improper maintenance. Regular inspections help prevent these problems.
