Industrial Big Fan 10ft-24ft AC 220V High Volume Low Speed Aluminum Alloy 5 Blades Industrial Hvls Ceiling Fan for Warehouse
Gearless direct drive hvls ceiling fan specially dedicated for large scale space. The streamlined fan blade adopts aerodynamics principles and advanced process, the diameter is from 2.4-7.2 meters, with coverage 14860m³/min. Only using the efficient direct drive motor, it can create plenty of comfortable natural wind.
It's only 880W/660W. 16 hours will spend only 14 kwh, and because it's no gearbox reducer, there is no need to maintenance, it's servo and can used more than 15 years.
Wire ropes in 4 directions to keep balance
4 wire ropes with 8mm to keep balance in 4 directions to prevent the fan in large inertial rotation shaking, guarantee operation stability and security.
Rare earth permanent magnet servo drive motor
1. IP64, small volume, no lubrication oil, low energy consumption with no maintenance, it can work for almost 15 years, beautiful appearance, specially for villa, church, cafe shop, restaurants etc.
2. Motor design with high heat pyrolysis technics, the running temperature is around 38℃.
Integrated control box
Servo drive system can make fan have a fast reaction with DSP control core and inner complex control algorithm. In addition, it has continuously variable, precise localization and the protection system with over voltage, over currents.
Fan blades
7075 aviation aluminum magnesium alloy with T6 anodizing heat treatment. High resistance to deformation and anti fracture. Tensile strength is 572mpa, the thickness is 2.00mm. 5 strength ribs in the inner fan, and one is 3mm thickness for more strong structure and not easy to deform and bench.
SKF bearing (deep groove ball bearing + thrust ball bearing)
Bearing transmission adopts high strength low alloy steel construction. Strong mechanical properties, precision measurement to ensure longer life.
High strength bolts and fasten glue
High strength bolt in level 12.9, made of 30 CrMnSi, with 271 screw fastening glue to prevent loosening.
What are the main advantages of a gearless direct drive HVLS fan?
Since there is no gearbox reducer, there is no need for oil lubrication maintenance. It operates with higher efficiency, consumes less energy (only 660W-880W), produces lower noise (≤39db), and offers a long service life of over 15 years.
How energy efficient is the industrial ceiling fan?
It is highly efficient. Running the fan for 16 hours consumes only about 14 kWh, making it a cost-effective cooling and ventilation solution for large commercial and industrial spaces.
What sizes are available, and what is the coverage area?
The fans are available in sizes of 10ft, 12ft, 14ft, and larger (diameter from 2.4 to 7.2 meters). They can cover a wide area and generate a massive air volume of up to 14,860 m³/min (or 1500m³/min-15000m³/min depending on the model).
How is the safety of the HVLS ceiling fan guaranteed?
Safety is ensured through multiple features: 4-direction 8mm wire ropes to prevent shaking during high-inertia rotation, level 12.9 high-strength bolts secured with 271 fastening glue, and a DSP-controlled integrated control box featuring built-in over-voltage and over-current protection.
What materials are used for the fan blades?
The blades are made from 7075 aviation aluminum-magnesium alloy with a T6 anodizing heat treatment. They have a thickness of 2.0mm, a tensile strength of 572MPa, and contain 5 internal strengthening ribs (including one 3mm thick rib) to prevent deformation and bending.
What applications are these fans suitable for?
These fans are ideal for high-space ventilation, including warehouses, workshops, meeting rooms, poultry farms, gymnasiums, churches, cafe shops, and restaurants.
