Stay Cool, Save Energy
By utilizing RTFANS's HVLS Fans, air coolers, and other systems, we can establish a comfortable indoor environment, enabling people to rest and work more effectively.
Driving Device
High efficiency PMSM (permanent magnet direct drive) motor without gear and lubrication oil replace.
Inner rotor motor, with permanent magnet made of neodymium iron boron in a mosaic structure.
IP64 level of protection, no need heat dissipation holes, long service life.
Plug-in temperature sensor with automatic over-temperature protection.
Multi-point installation, fixing and balancing the force, effectively reduce the jitter and shake, improving the safety.
Compact and light design, no space limitation and easy to install.
Hub Wheel
Imported Aeronautic Aluminum Alloy (AA7075);
Unique Double Wheel Hub design;
High pressure forging technology, with T6 thermal treatment process & CNC precision machining & dynamic balance test of the complete set chassis & 40 times strength test.
RTFANS VFD Controlling
(Standard Configuration)
VFD inverter controller, with stepless speed regulation;
With safety protection module inside, over-current, over-voltage, lack of phase, etc.
Fan Blade
High strength aircraft Aluminum alloy: AA6063T6511 with fluorocarbon coating surface processing;
Patented airfoil design with special reinforce rib support system which increase the strength of fan blade and avoids the sagging of fan tail and fatigue loss of connecting components."
MOUNTING BRACKET
Adopt traditional mortise & tenon structure design with robot welding, more safer and reliable;
Anti-skip design, more safety and reliable.
Q345 high strength steel panel with anti-rusty coating.
Save Energy Cost Up To 30%
Cover 1000m² + with only 1.5kw!
Big industrial ceiling fans are energy efficient,cost-effective and can provide massive air movement in large industrial and commercial spaces.
CARDAN JOINT
Unique cardan joint design, working as a human beings’ joint, to decrease the shocking of fan during running.
4 directions are adjustable, keeping the fan horizontal and vertical when installed in a sloped position.
MOTOR FRAME
Mortise and Tenon Joint Structure welded by Robot.
Two L-shape Q345B high-strength steel plates connected with the top cover of the motor frame.
The motor is fixed by the two circular high-strength steel plates connected with 6 pcs longer screws and glue.
With high strength 8.8 grade industrial Bolt and Locknut.
Anti-Drop Device
Patented design Anti-drop structure make the fan blade and chassis into a intergated structure; (Patented No.:202020632563.3)
The MAX bearing capacity of the anti-drop is over 32 tons(the fan blade and chassis structure is 75 kg only), which helps to prevent any risk of falling off.
Fan Blade Plug Connection
- High strength aircraft Aluminum alloy: AA7075 Sereis;
- The blades are installed in the interpolation type, which increases the contact area between the blade plug and the inner wall of the blade and improves the force performance on the blade and the blade plug, bettering its security.
Safety Retainer
6 pcs airfoils are connected into a whole with 6 pcs safety retainer.
Fasteners
German DIN933 Industrial Bolt and DIN125A locknut with high strength 8.8 grade, the practical stress it could endure is 10 times than normal.
Packaging
Standard Export Package.
