The core features of industrial energy-saving ceiling fans (HVLS, high air volume, low-speed fans) include large coverage, ultra-low energy consumption, silent stability, three-dimensional breeze, safety and durability, intelligent control, specially designed for tall and open spaces.
1、 Core design and performance characteristics
Ultra large diameter, wide coverage
Diameter: 3.1~8 meters (mainstream 6.1/7.3 meters)
Single unit coverage: 800~2000 ㎡
Principle: Air pressure → Horizontal diffusion on the ground → Formation of a 1-3m/s three-dimensional breeze cycle
High air volume, low speed (core)
Speed: 20~70 RPM (very low)
Airflow: 10000~17000 m ³/min
Fan blade: wing shaped aerodynamic design (aluminum alloy/fiberglass), with low drag and high efficiency
Extremely energy-efficient (core advantage)
Power: Only 1.1~1.5kW (household air conditioning grade)
Power saving: 50%~90% less than small fan groups; Cooperate with air conditioning to save 20%~50%
Motor: Permanent magnet synchronous (PMSM/IE4), direct drive without gearbox, efficiency * * ≥ 92%**
Natural breeze, high comfort level
Sensory cooling: 3-8 ℃ (accelerated evaporation)
No rigid blowing, no turbulence of airflow
Thermal stratification: uniform upper and lower temperatures, dehumidification and mold prevention
2、 Structure and durability characteristics
Quiet and Low Noise
Noise: 38~52 dB (library grade)
No electromagnetic/mechanical noise
Ultra long lifespan, maintenance free
Design lifespan: 15-20 years
Motor: IP55 dustproof, waterproof, sealed, oil-free
Low temperature rise, low failure rate, maintenance cost ≈ 0
Multiple security protections
Triple anti fall (fan blades, motor, chassis)
Safety ring, anti detachment plate, steel wire rope (bearing capacity ≥ 1000kg)
High strength wheel hub, anti fatigue design
3、 Intelligent and installation features
Intelligent frequency conversion control
Stepless speed regulation, soft start and soft stop
25+protections for overvoltage/overcurrent/overheating/vibration
Optional: Internet of Things, remote monitoring, timing, group control
Wide installation adaptability
Applicable: Factory buildings, warehouses, logistics centers, sports venues, supermarkets
Height: ≥ 3.5m; compatible with steel beams/concrete structures
Modular and easy to replace
4、 Value Summary
Energy saving and cost reduction: saving thousands to tens of thousands of kilowatt hours annually, with a return on investment in 1-3 years
Green and low-carbon: Significant carbon reduction, in line with dual carbon/green factories
Improving quality and efficiency: employee comfort, controllable humidity, increased production capacity and cargo safety
Low consumption and long lifespan: almost zero maintenance, low lifecycle cost
