Fan range :3m,3.7m,4.3m,5m,6.1m,6.7m and 7.3m
Advantages of our HVLS FANS
1 Ceiling fan operation: independent research and development of permanent magnet external rotary motor
2 Fan blade: aluminum magnesium alloy extrusion molding, wing type inside reinforced structure, with high strength, good toughness, light weight, long life, safety and other advantages
3 Anti-tripping device: top safety, fan blade, chassis, motor connected as a whole, anti-tripping plate plays a protective role, to prevent any parts falling off.
4 Tail: the high temperature resistant material is used to make the product structure more beautiful. When the fan blade is running, the air will produce eddy current at the end of the airfoil. The tail can eliminate this part of the energy loss, stabilize the fan operation, and make the air flow more in line with the principle of aerodynamics.
5 Steel wire locking device - high altitude protection, steel wire cable stress intensity up
to 1000kg/ root, keep the fan rotating when the huge inertia of stable and reliable operation.
Main Features

3) Airfoil blade
4) Energy saving tail
5) Variable speed 1m-5m/s
6) Super mute 38db
7) Five security
8) Insurance, each sold ceiling fan has $150,000 sum insured
Permanent magnet synchronous motor
The new self-developed external rotor motor with large torque and permanent magnet synchronization replaces the traditional motor+gearbox reducer, achieving a high degree of integration and improving reliability and transmission efficiency.
Aluminium alloy material is adopted in many parts to realize the lightweight design.
PMSM :0.37kw,0.75kw,1.1kw,1.5kw
Smart control system
1 FI110 Controller,IP54
2 EM30 Controller,IP66
A The system function is simple, 4 buttons easy to operation( start, stop, speed up, slow down).
.
B With thermal protection
Fan blade
It is made of aluminium and magnesium alloy extruded and stretched, and has the advantages of high strength, good toughness, lightweight, long life and safe operation. The fan blade surface is treated with T5+ bright surface oxidation treatment, which enhances the corrosion and oxidation resistance of the fan blade and can cope with special environmental operations.
Energy saving tail.
Five Levels Of Security Guarantee
Motor bracket is integrated to prevent any parts from falling off and ensure the safety of the whole structure.
Anti-off-plate break-off protection structure design ensures the safety of the ceiling fan.
Aluminum magnesium alloy tensile blade, internal reinforcement structure, strength, toughness, to ensure the safety of the blade.
IE 5 standard low power consumption PMSM
Permanent Magnet Motor Ceiling Fan VS Gear Box Variable Speed Ceiling Fan
1)Permanent magnet synchronous high-temperature resistant out rotor motor, super energy efficient.
2) Small size and light weight.
3) Low noise. 38db
4) Simple structure.
5) Frequency modulation width (0-50HZ)
6) Direct drive motor maintenance free
7) No running hazard.
1) The use of asynchronous ordinary motor+gear box consumes a lot of energy.
2) Large and heavy.
3) Loud noise 60db.
4) Complex structure.
5) FM narrow (25-50HZ)
6) Need frequent daily maintenance (change seals, add gearbox oil.)
7) There are hidden dangers such as gearbox leakage.
