D.FANS SERIES

——

D.FANS series industrial large fan is a new type of HVLS energy-saving super large industrial fan independently developed by Company Ventilation based on aerodynamics principles. It has low speed, large air volume, and no dead angle air circulation, promoting 1-3 levels of natural wind effect. It can eliminate high temperature and stuffiness, balance air humidity, increase space oxygen content, smoke and dust removal, reduce bacterial concentration, and effectively solve problems such as stuffiness and humidity, airflow stratification, and dust retention in tall spaces.

D.fans Series Fan Features

——

No.1 / Electric machinery: german nord or other brands of the same level

1. High energy efficiency: Meet the IE2 high-efficiency and energy-saving standards, saving 5-10% energy compared to IE1;
2. High reliability: High axial and radial bearing capacity, ensuring operational reliability;
3. ​Low noise: low backlash assembly process and gear grinding process, with low vibration and lower noise;
4. High safety factor: Strengthen the bearing frame structure, trapezoidal shaft structure, increase oil seal, strengthen the body structure, and achieve higher safety factor:
5. Certified by CCC, CE, UL.

No.2 / Control system:variable frequency control

1. Easy debugging, built-in application macros, no need for self-learning;
2. Excellent performance, perfectly matching the operating parameters of the load motor;
3. Low noise operation, optimized algorithm control for smooth start-up;
4. Safe and reliable, with built-in multiple protection programs to enhance product life.

No.3 / Wheel Hub Chassis

1. Better mechanical performance: Made of 6061T6 aviation grade aluminum material processed by CNC lathe and CNC precision machining process, the appearance remains highly consistent, the metal flow line is complete, and the chassis has better mechanical performance;
2. More precise dynamic balance: After CNC machining, the chassis accuracy tolerance is controlled at 100um, ensuring accurate dynamic balance of the chassis.

No.4 / Fan blades:variable cross-section streamline aviation fan blade

1. 5052H32 aviation grade aluminum plate material, 1.5MM thick, with 5 blades capable of withstanding a tensile force of more than 3 tons, without breaking upon impact;
2. Variable cross-section streamline fan blade: the blade gradually narrows from the root to the tip, thins and widens at the tail, with more balanced force, no fracture risk, less wind resistance, more uniform air flow and no cavity in the middle;
3. Lighter and safer: The 7.3 meter fan blade weighs only 6.7KG per piece, making it lighter and safer

No.5 / Mortise and tenon connection:

The full mortise and tenon connection structure ensures the overall safety of the fan

1.Motor and chassis: Tightly connected through inner and outer cones, even if the motor shaft is loose and broken, the inner and outer cones form a structural self-locking to prevent falling;
2.Chassis and blade handle: The blade handle is connected to the chassis through a hook type mortise and tenon joint, and the bolts are not under force, ensuring overall strength;
3.Blade and petiole: closely matched with the blade buffer chamber, efficiently releasing the vibration and stress generated by blade rotation, eliminating resonance, reducing motor load, and extending service life.

Core Technology 

Blade Design:Streamline Variable Cross-Section

1. Blade design: streamlined variable cross-section

Through aerodynamic simulation analysis, applying equal chord length theory, combined with the principle of relative linear velocity, a streamline variable cross-section fan blade was developed and designed, which gradually narrowed and thinned from blade root to tip, with more balanced force, more uniform air supply, and no cavity in the center.

2. Blade Material Selection:Aviation Grade Industrial Alloy Plate

Adopting 5052H32 high grade 1.5mm aviation grade aluminum alloy motherboard, precision CNC forming, higher strength and flexibility, ensuring no fracture. Lighter and safer in weight. Each blade only weighs 6.7 kilograms (7.3 meters in diameter, excluding buffer parts), with a small number of blades and light weight, reducing motor load, extending service life, and ensuring safety and energy conservation.

3. Blade Connection - Multi Point Riveting Process

16 high-strength steel core rivets are separated and riveted up and down (a single rivet can withstand 1500kg tension), forming independent surfaces on the upper and lower layers of the blades to withstand the strong centrifugal force when the fan is running at full speed.

Patented Buffer Structure : Efficient Fan Components

1. Shock-absorption Rubber

With high-precision coordination with the blade buffer chamber, it efficiently absorbs stress and airflow vibration from the blade, reduces motor load, and extends service life.

2.  1 ° Micro Upward

There is a precise angle limit in the buffer chamber, and the blade handle is connected to the buffer chamber to form a 1 ° micro upward movement, effectively eliminating the reverse force generated during the fan operation and forming a conical airflow, achieving no voids in the center and increasing coverage.

Patent Integrated Hub:the core of fan safety

Patent Integrated Hub

By interlocking the upper and lower pressure plates with the concave and convex steps of the blade handle, the blade handle is integrated with the hub/motor, and the overall structure is used to withstand the centrifugal force during fan operation, without any stress on all fasteners.

Patent Inner Cone Shaft Sleeve

A patent inner cone kit is installed in the center of the hub, forming a structural self-locking with the output of the inner rotor motor, which naturally expands and tightens under the action of gravity, ensuring reliable connection between the overall hub and the motor.

Safety Anti Fall Structure

Anti fall ring and inner rotor motor: connect 5 blade handles with the anti fall ring through bolts, and form a sleeve hanging with the chassis of the frame to prevent falling due to wheel hub detachment or shaft breakage;

Anti Fall Ring And Outer Rotor Motor

The anti fall ring forms a collar with the motor flange, ensuring effective hooking in the event of motor shaft breakage and ensuring safe operation.
