The DM.FANS series is a hand pushed mobile HVLS large fan independently developed and designed by companybased on the PMSM permanent magnet synchronous principle. The DM.FANS series with ultra wide angle air supply can supply air of over 40M, bringing a cooling effect equivalent to more than 30 small fans. Its easy to push casters can pass through any standard entrance, suitable for more indoor and outdoor places that require ventilation and cooling, such as workshops/gyms/outdoor events.
D.fans Series Fan Features
1. More convenient
No installation, plug and play. The four casters with side brakes can move freely, adapting to the constantly changing needs of personnel's workplaces.
2. More energy-efficient
Adopting pmsm permanent magnet synchronous motor, it saves energy by 30%, meets the ie4 high-efficiency and energy-saving standard, and meets the new national energy efficiency standard of gb30253-2013.
3. Lifetime maintenance free
Completely sealed, without the need to replace lubricating oil/oil seals and other accessories, saving a large amount of maintenance costs in the later stage.
4. More muted
Subwoofer volume, only the sound of the wind in my ear
5. Longer lifespan
The upper limit of motor temperature rise is 120 ° c, which will not demagnetize and has a longer lifespan! The working life of the drive control capacitor can reach 32000 hours!
6. CMore durable
Adopting golden hair reinforced pp material, precision cnc molding, higher strength and flexibility, ensuring no fracture.
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.
1. Intelligent manag ement
① Centralized control and manag ement of all fans in the samework shop/area, a single control terminal can manage and controlup to 48 fans.
② The speed can be se tuniformly,the fan can be switched on andoff at regular intervals to avoid repeated operations by personnel and reduce equipment damage.
③ Wireless communication, avoiding complicated and long-distance wiring, remote control by mobile phone APP.
2. Operation supe rvision
① 7*24 hour s real-time monitoring of oper ating data.
② Real-time monitoring, monitoring the running status anytime and anywhere.
③ Real-time alarm fore quipment abnorm a lities, accurate diagnosis of fault causes and generation of fault codes, real-time transmission
3. Remote a tier-sales se rvice
Receive equipment failure alarms in real time ,quickly generatemaintenance plans based on diagnostic data, improve collaboration
efficiency with users,quickly solve On-site problems,provide userswith betier service.
