About this product

The HAVAI 6-Inch BLDC Inline Duct Fan is a premium ventilation solution designed for industrial, commercial, and residential HVAC applications where performance, efficiency, and reliability matter most. Engineered with an advanced Brushless DC motor, this fan consumes only 28 watts while delivering a powerful 540 m³/h airflow and 300 Pa static pressure — ensuring consistent ventilation even across long and complex duct lines. Unlike conventional AC duct fans, the BLDC motor offers superior torque, cooler operation, and zero maintenance on winding or brushes. Its balanced 1700 RPM rotor guarantees smooth, vibration-free performance, ideal for continuous 24×7 usage in HVAC systems, warehouses, server rooms, laboratories, grow tents, and industrial air-handling setups. Despite its compact and lightweight 1.97 kg body, the HAVAI Inline Duct Fan is built tough using industrial-grade ABS material, ensuring corrosion resistance and long-term durability. The fan operates quietly at just 30–31 dB, making it suitable for noise-sensitive environments such as offices, kitchens, and cleanrooms. To maintain the fan’s efficiency and long life, regular cleaning of the blades and duct area is recommended. Periodic maintenance helps prevent dust accumulation, ensuring smooth airflow and preventing motor strain — keeping your fan running at its best for years. The wide voltage range (200–240V) allows stable operation even under power fluctuations common in industrial grids. Its compact cylindrical design makes installation simple in both horizontal and vertical orientations, integrating seamlessly into HVAC ducts, exhaust setups, or ventilation networks.
