Product Description

HVLS Industrial Ceiling Fan for Large Factory & Warehouse Ventilation

Industrial HVLS (High Volume, Low Speed) Ceiling Fan is designed for large industrial spaces such as factories, warehouses, logistics centers, and workshops. With an ultra-large diameter and low-speed operation, it delivers powerful airflow to cover wide areas efficiently, improving air circulation, reducing heat stress, and enhancing working comfort. Featuring energy-saving performance, quiet operation, and durable construction, HVLS fans significantly lower cooling costs while maintaining stable ventilation in high-ceiling industrial environments.

Product Description

Aviation-Grade Magnesium-Aluminum Alloy Blades

German ABM Gear Motor Drive System

Japanese Nidec Variable Frequency Drive (VFD)

Manufactured from aviation-grade magnesium-aluminum alloy, the blades feature high structural strength combined with lightweight construction.
The aerodynamic airfoil profile with a hollow internal structure reduces rotational inertia, enabling higher airflow output at low rotational speed. This design ensures stable operation, improved energy efficiency, and long-term durability for large-scale industrial environments.

Powered by a German ABM industrial-grade gear motor, engineered for continuous heavy-duty operation.
The high-torque, low-speed direct-drive design delivers smooth and stable performance with low noise and minimal vibration, significantly enhancing system reliability and extending service life in large industrial facilities.

Equipped with a Japanese Nidec industrial variable frequency drive for precise speed regulation and intelligent control.
The VFD supports soft start, overload protection, and multiple safety functions, reducing electrical impact during startup and optimizing energy consumption while ensuring safe and efficient operation.
