Introduction
Belt Drive Fan is a mechanical ventilation device, the motor transmits power to the fan shaft via a belt and pulley system. This setup enables indirect drive, allowing for adjustments in fan speed by changing pulley sizes.
Features
Stable Operation Capability Over a Wide Temperature Range
The Belt Drive Fan is made of special alloy steel and equipped with a 0-200mm adjustable insulation layer, which can operate stably in an extreme temperature range of 20℃ to 850℃.
Precise Adjustment of Air Volume Over a Wide Range
Our air volume covers 1000 to 300000 m³/h, and 15% air volume fine-tuning can be achieved by adjusting the pulley diameter. Actual measured data shows that the energy efficiency is 8% higher than that of direct-drive fans at an air volume of 20000 m³/h, and the operating efficiency is still maintained at 82% under the maximum air volume condition.
Reliable Operation Under High Pressure Conditions
Our products have an operating pressure range of 500 to 8000Pa, and adopt a reinforced cast iron base and a double bearing support structure. The shaft displacement was controlled within 0.05mm after 2000 hours of test operation under an extreme pressure of 8000Pa.
Applications
Industrial Ventilation System
The Belt Drive Fan is widely used in ventilation systems such as large factories, workshops, and storage centers.
Boiler and Hot Air System Air Supply/Induction
Used for the delivery or extraction of high-temperature gases in boiler rooms, drying furnaces, hot air furnaces, etc.
Dust Removal System Matching Use
Used with bag dust collectors, cyclone dust collectors, etc., to collect and discharge dust-containing gases.
Paint Room and Organic Waste Gas Treatment System
Used in spray workshops, paint rooms, and other places where volatile organic compounds (VOCs) are emitted.

FAQ
Q: What is a belt drive fan and how does it work?
A: A belt drive fan uses a belt and pulley system to connect the motor and fan shaft. The motor drives the pulley, which turns the fan blades. This setup allows for flexible speed adjustment by changing pulley sizes and helps isolate motor vibration from the fan.
Q: What are the advantages of a belt drive fan over a direct drive fan?
A: Belt drive fans offer greater flexibility in airflow and speed control, making them ideal for larger systems or where specific air volumes are needed. They're also better for applications requiring motors to be placed away from high-heat or contaminated air streams.
Q: In which applications are belt drive fans commonly used?
A: They are widely used in HVAC systems, spray booths, warehouses, industrial ventilation, and dust collection systems-especially where variable airflow or high static pressure is required.
Q: What maintenance is required for a belt drive fan?
A: Maintenance includes checking and adjusting belt tension, inspecting for belt wear, lubricating bearings, and cleaning the fan blades. Proper maintenance ensures energy efficiency and extends the service life of both the belt and motor.
Q: How do you select the right belt drive fan for your system?
A: Selection depends on airflow (CFM), static pressure (Pa or inches of water gauge), application type, duct configuration, and installation space. Material, noise level, and motor positioning also play key roles in ensuring optimal performance.
