Conclusion & Contact Us
A Centrifugal Type Exhaust Fan is a mechanical device that moves air or gas using the centrifugal force generated by a rotating impeller. Unlike axial fans, which move air parallel to the shaft, centrifugal fans push air outward at a 90-degree angle through a duct system, creating higher pressure suitable for long-distance ventilation.
When the fan blades rotate, air enters the fan housing and is thrown outward by centrifugal action. This increase in air velocity converts into pressure, which is then used to push the air through ventilation ducts or exhaust outlets.
This design makes centrifugal fans highly efficient in extracting contaminated air, fumes, or heat from enclosed spaces, especially in factories, workshops, kitchens, and warehouses.
High-pressure output and strong air delivery
Low noise and vibration due to balanced impeller design
Long service life with minimal maintenance
Capable of handling air with dust or light particles
Selecting the right ventilation fan can significantly influence air circulation efficiency, power consumption, and indoor comfort. Here's why the Centrifugal Type Exhaust Fan is an ideal choice:
Superior Airflow Efficiency – Designed to handle higher air pressure, ensuring stable exhaust even in large or multi-duct systems.
Energy-Saving Performance – Optimized impeller design reduces power loss, achieving better airflow with lower energy consumption.
Durability and Safety – The fans are made from high-strength steel or anti-corrosive materials to withstand harsh environments.
Versatile Applications – Suitable for ventilation in factories, kitchens, warehouses, offices, and agricultural buildings.
Low Maintenance Design – Easy to disassemble and clean, ensuring long-term reliability.
