How RTFANS ensures the safety of large HVLS fans？

In the hot summer, large HVLS fans have become a necessity for ventilation and cooling in tall spaces. They achieve cooling and air circulation effects with minimum energy consumption and maximum coverage. As global temperatures rise, large HVLS fan units are becoming increasingly popular.

Wherever there are large HVLS fans, there must be people and goods. Therefore, how to effectively ensure the safety of large HVLS fans has become the most important requirement.

RTFANS has been people-oriented and safety-oriented from the beginning of its design. It ensures the safety of large HVLS fans from the following aspects to the greatest extent, making your use simpler, safer and more energy-saving.

Mounting Bracket design:

1. High strength Q345B steel, PVDF processed on surface;

2. Unique Anti-Skip design, safe and reliable.

3. Optional H beam, Rigid frame (C-type Steel and Spheric frame) and Concrete installation structure, can be customized for special structure.

Unique cardan joint design：

1. Working as a human beings’ joint, this allows the fan to find its own balance no matter what’s the slope of the building.

2. Help to decrease the shocking of fan during running.

Safe Steel Cable design:

1.Safe steel cable around the roof steel structure and connected with

?the extension rod and form a closed loop,

2. Help to connect the mounting bracket as a whole, safe and

reliable.

3. One steel cable can sustain 1000kgs stress.

Motor Frame design:

1.Mortise and Tenon Joint Structure plus robot welding, double safety assurance.

2.Two L-shape Q345B high strength steel plate connected with the top cover of the motor frame.

3.The motor is fixed by two circular high-strength steel plates, which are connected and bonded with 6 extension screws.

4. With high strength 8.8 grade industrial Bolt and Locknut.

Hub Wheel design:

1.Unique Double Wheel Hub design; the fan blade holder is fixed by the upper and lower hub wheel.

2.Imported Aeronautic Aluminum Alloy (6061-T6).

3.High pressure forging technology, with T6 thermal treatment process & CNC precision machining & dynamic balance test of the complete set chassis

4.40 times strength test.

Fan Blade design:

1.High strength aircraft Aluminum alloy: AA6063T6511 with fluorocarbon coating and surface

processing.

2. 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.

Fan blade Holder design:

1.High strength aircraft Aluminum alloy: AA7075-T6

2.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 holder, safe and reliable.

Safe Retainer design:

6 Pcs or 5Pcs fan blades are connected into a whole with 6 Pcs or 5Pcs safety retainers.

Fasteners design:

German DIN933 Industrial Bolt and DIN125A locknut with high strength 8.8 grade, the practical stress it could endure is 10 times than normal.

Professional installation guide:

Distributors in more than 50 countries around the world are ready to provide you with the necessary on-site, telephone, video installation help.

Insurance for the products：

RTFANS products are covered by Pacific Insurance Agency with total amount up to 1.5M in USD.
