Products Description

PERMANENT MAGNET LARGE FAN

01 / LARGE AIR VOLUME COVERAGE When running, reduce the resistance of electricenergy efficient conversion of air energy, for the downward transmission ofa large amount of air, so as to form a 1-3m airflow layer on the ground, in theopen field, the air coverage can reach 1000-1500 square meters.

02/PERSONNELCOOLING Super large energy-saving fan can produce a similar large area of naturalsoft air supply, three dimensional blowing of the human body from all sidespromote the evaporation of sweat to take away the body heat, and the humanbody feels the temperature drop 3-5°

03 / DEHUMIDIFICATION AND MOISTURE

RESISTANCE The use of industrial large fans can promotethe circulation of air, disperse the smoke and moisture in the air and quickly discharge the room to improve the indoor air quality. lt can also effectivelyprevent the problem of mold and achieve the effect of safe storage and protection of products.

Permanent magnet motor

●High torque permanent magnet synchronous motor, the motor is integrally installed on the axle to form an overall direct drive system, that is one axle is one drive unit to

maintenance-free.The tenslie strenght can reach 595MPa,and maintenance is not required.

Fan blade connection system

● Connecting the chassis and the fan blades, safety here is very important. Bichen uses the outer clip aviation hard aluminum material.Tested and certified by authoritative organizations. The ultra-high hardness ensures that the fan blade does not fall off when it
operates for a long time, ensuring the safety of the product.

Variable-frequency drive

● The integrated frequency conversion control system can effectively prevent the impact. And built-in overload and overcurrent protection, automatically cut off the power output in the event of an accident, improving the safety factor. The operation is simple, the control system only needs to turn the speed control button to meet the needs of different wind conditions, the protection of the inverter and the cooling fan is more reliable, the control box is safe, and the service life is longer.

FEATURES AT A GLANCE

Extra large air volume coverage

In operation, the streamlined ultra-long fan blade made by the aerodynamic principle and advanced technology can transport a large amount of air flow outward and form a super-large range of air flow layer..

Title goes here.

Operation to produce full coverage of the full range of air supply function, large ceiling fan downward transport with a feeling similar to the natural wind. Large area blowing to every corner of the human body, a full range of three-dimensional blowing wind,so that the human body by the wind area to the maximum.

Aluminium alloy blade

●The enlarged alloy aluminum alloy fan blade is used, and the built-in reinforcing ribs are supported up and down to ensure the strength and hardness of the fan blade, and the safety factor is significant. The surface is oxidized.
●Fan leaves after complex oxidation and then paint secondary treatment (adhesion is 0), no cleaning, no deformation.

Title goes here.

● 1. Large indoor space, poor ventilation and poor air circulation 2. The environment is hot and uncomfortable, and employees are
in high mood 3. Traditional air conditioning costs a lot and consumes a lot of power 4. Adverse reactions caused by long-term air conditioning by personnel 5. Heat and humidity cause mildew of raw materials

Personnel to cool

When the fan is running, it can produce a large area of natural and soft air, blow the body three-dimensional in all directions,promote the evaporation of sweat to take away the body heat, and the human body feels the temperature to drop 3-5°

Doesn't take up interior space

Installed at the top of the room, will not occupy the indoor ground space, at the same time to avoid the use of traditional fans placed too much impact on the indoor appearance, wiring complex security risks, not only save space and achieve practical and beautiful.
