24ft 7.3m Large Ceiling Fans with Geared Motor Large Coverage for Large Space

Vanse Large Ceiling Fans is special designed for large space, low speed and high volume, perfectly solved ventilation, cooling, drying and mould proof in large space.

Vansefans streamlined variable section blade rotate slowly, pushing the airflow in cone from ceiling to floor, generating efficient and horizontal airflow with three-dimensional cycle.

The 30 up blades cover 6 times than its own diameter. The airflow can up to 65ft from the fan center. The horizontal airflow moves outwards until encounters wall, obstacle or other airflow then push it to the ceiling,thereby enhance the air circulation and destratification.

-----Configuration-----

1. Power: NORD or Wqual Gear Motor

1).Low gear gap assembly process, gear grinding process, low noise.

2).Strengthen the bearing frame structure, trapezoid out of the shaft structure, strengthen the body structure, more safety.

3).Get CCC、CE、UL certification.

4).No vibration, silence, free maintenance.

2. Controller: Vector Converter

1).Start steady: Motor vector algorithm and current suppression to achieve.

2).No noise: up to 16KHZ, no noise during speed up, slow down, and running.

3).Failure protection: 25fail-safe protections (over current,over voltage,under voltage phase loss,overload,etc.)

3.  Fan Blade *patent: Variable Cross-section Streamlined Blade

1).5 pieces of 1.5mm thick 5052 aero-grade aluminum plate are adopted, which can withstand more than 3 tons of tension and will not crack when impact.

2).Variable cross-section streamlined blade: fan blade gradually narrows from root to tip and thins to the tail then widens,wind resistance is small, air volume is more uniform.

4.  Connection *patent: Structural Connection System

1).Petiole and chassis are connected by trapezoidal ladder clamping groove, and the structure is stressed as a whole without the risk of bolt fracture.

2).Petiole and blade adopt flexible shock absorber to release high-frequency vibration and ensure that the bolts are not impacted.

5. Chassis Assembly: Integrated Chassis

7075 aero-grade aluminum material is made by CNC lathe machining with precision process, the shape remains totally same,  well appearance to ensure the best mechanical performance of chassis.

-----Security Guarantee-----

1. Steel Wire Rope Protection

Connector and I Beam are winded with 1000KG (2205Ibs) tensile wire rope to prevent the fan from sliding and falling.

2. Wire Rope Balance Protection

Four wire ropes are fixed with building traction to prevent the fan from shaking and falling .

3. Anti-falling Safety Ring

Safety ring connects electric unit with hub, forming integration to prevent the broken shaft from falling apart.

4. Anti-fall Self-locking Device

Motor output shaft tension device(patented design), forms self-locking to ensure the hub and shaft firmly fastened together.

5. Integrated Hub

Integrated hub embedded with 5 shaped fasteners to support minimum 11T(24244Ibs) tensile .

6. Mortise and Tenon Petiole Connection

The petiole and convex-concave buffer device locked with bolts forms a whole to avoid blades subject to cutting forces.

7. Buffer Device

The blade and petiole flexible connected with buffer device,special rubber pad absorbs most of the vibration caused by blade rotation.

8. Blade High-strength Connection

Each blade fixed with buffer device by 16 rivets.Each rivet can load 1.5T(3306Ibs )shear. 

9. Aviation Aluminum Plate

1.5MM thickness 5052 aviation aluminum plate can load minimum 3T(6612Ibs) tensile to ensure the blades will not break when impacted.

10. Abnormal Alarm System 

Control system equipped with protection when over-voltage, overload and phase loss. The fan will automatically alarm and stop work.
