Frequently Asked Questions

Q:What are the main advantages of using these HVLS ceiling fans?

HVLS (High-Volume Low-Speed) ceiling fans provide highly efficient airflow over large application areas with low maintenance costs. The 5-blade design produces higher CFM (Cubic Feet per Minute) at a lower RPM, keeping spaces cool in the summer and distributing heat in the winter.

Q:What size options are available for the fans, and what are their weights?

The fans are available in three main diameters: 7.3 meters (24 feet) weighing 128 Kg, 6.1 meters (20 feet) weighing 125 Kg, and 5.5 meters (18 feet) weighing 116 Kg.

Q:What type of motor and control systems are used?

These fans feature a specially designed German NORD motor with an original NORD reducer. The control system uses a premium Danfoss brand unit that handles high carrier frequencies to reduce motor noise and optimize the control pulse signal quality with an IP55 protection rating.

Q:How are the fan blades secured to prevent them from falling?

Safety is ensured through high-quality aluminum magnesium alloy blade clips with a double-length plug-in design. Additionally, an anti-falling loop-shaped device connects all the blades tightly to the hub, and a safety ring prevents components from falling if any breakage occurs.

Q:What electrical specifications and noise levels can I expect?

The fans operate on a 380V current ranging from 2.32A to 3.23A depending on the model, with a motor power of 1.5/2.0 KW. The noise level for all models is kept low at a comfortable 45 dBA.

Q:What emergency safety protection systems are included?

The safety mechanism features Grade 12.9 high-strength industrial bolts, a 6mm hot-dip galvanized safety rope capable of holding up to 1000KGS, and an automatic alarm & shutdown mechanism controlled by the Danfoss Control Unit in case of emergency.
