Large Industrial Ceiling Fans
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.

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.
10+ Security Guarantees
Ensure industrial large fans run safely, easily copes with various harsh operating environments
|Fall arrest safety ring
Connect the 5 leaf stems with the motor cover to ensure that the leaf stems do not separate and fall
|Wire Rope Winding Protection
The installation plate and beam are wrapped with 1000KG tensile strength steel wire rope to ensure that the overall structure of the fan is not loose or falling.
|Anti fall self-locking device
The motor output shaft tightening device (patented inner cone design) forms a structural self-locking mechanism, ensuring that the hub and output shaft are not loosened.
The patented integrated wheel hub is embedded with 5 special-shaped fasteners, which are self-contained and can withstand a tensile force of over 11 tons after being tested by authoritative government departments.
|Real time monitoring and proactive maintenance
The Dawang Intelligent Remote Control System monitors equipment operating parameters, motor temperature rise, and equipment levelness in real-time.capacity of 1.5 tons.
|Streamlined variable cross-secttion designed:
Adopting the theor y of equal chor d length i n ae rodynamics, c ombined with the principle of r elative linear v elocity, the blade gets narrower and thinner gr adually from the blade root to blade tip, the f orce on the blades is mor e balance d, making blade mo ve air more uniformly without any hole s underneath the fan.
|Abnormal alarm system
The variable frequency control system comes with overvoltage, overload, and short circuit accident protection, and automatically alarms and stops the fan operation when encountering abnormalities.
|Steel wire rope balance protection
The four steel wire ropes utilize the principle of balance and are fixed by the building's traction, ensuring that the fan machine is not swayed or dropped by external forces and airflow.
|High strength riveting of blades
Each blade is riveted together with 16 high-strength rivets and the buffer chamber from top to bottom, forming an independent surface for stress. Each rivet is designed to carry a shear capacity of 1.5 tons.
|Mortise and tenon style blade handle connection
Mortise and tenon connection: The "concave" section of the blade handle forms a joint with the "convex" section of the buffer, eliminating the centrifugal force outward from the blade during fan operation and the shear force during fan start and stop.
|Anti desoldering safety module
The L-shaped connection device firmly connects the flange plate of the rack to its column, even if the flange plate is detached from the column, the overall rack structure is firm and does not fall.
|Damping and buffering device
Petioles are made of 6061T6 aviation-grade Aluminum alloy coated wtih polyurethane rubber, which match the buffer cavity of blade perfectly. It can release the blade stress & airflow vibration generated by the blade when i t runs, and eliminate resonance efficiently, and this he motor load and prolong the mot or life.
|Material of aviation grade anti-collision blades
1.5MM thick 5052 aviation aluminum plate can withstand a tensile force of more than 3 tons, with ultra-high material toughness, ensuring that the blades can quickly transform and effectively absorb external forces when impacted, preventing blade fracture while greatly avoiding damage to the motor and other structural components.
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.
