Why HVLS PMSM Fans?

  • PMSM itself has high power, high efficiency, and higher torque. Compared with traditional motor fans, any speed point can save power, especially at low speeds;
  • PMSM has low heat generation, so the motor has a simple structure in its cooling system;
  • Small size and low noise, HVLS PMSM FANS is suitable for installation in space with lower ceilings;
  • PMSM has no transmission gear wear, no lubrication, thus no maintenance need;
  • PMSM allows large overload current, and the reliability is significantly improved.

What is PMSM Fan?

Synchronous motor
PMSM is a permanent magnet synchronous motor. What is called a permanent magnet, refers to adding permanent magnets when manufacturing the rotor of the motor in order to improve the performance of the motor. The synchronous means that the rotation speed of the rotor is always consistent with the electric current frequency of the stator winding.
Permanent magnet motors have a higher power-to-weight ratio, smaller size, lighter weight, and larger output torque than other types of motors, and the motor’s limit speed and braking performance are also excellent, so it is the most used motor in electric products at present.

Wind Chill Effect

The breeze brought by the HVLS fans blows toward the human body from a tridimensional direction, accelerating the evaporation of sweat, and making people feel cool. Usually, the temperature caused by the wind chill effect can reach 5-7°C. In addition, compared with traditional powerful fans, the breeze from all directions will make people more comfortable.

Feature of RTFANS Industrial HVLS Ceiling Fans

Wide coverage with power saving, fan diameter up to 7.3m, the maximum coverage area of each fan is more than 1000 square meters with the maximum power of 1.5KW;​
  • Tridimensional wind, 360-degree air circulation, ventilation without blind spots, ventilation, and cooling as well as dehumidification;​
  • The airfoil blades developed by scientific design and advanced aerodynamic technology and principles enable greater air volume and higher efficiency, such as the shape, Full, and Separate Connect Reinforce Rib​
  • Easy installation, elegant appearance, HVLS Fans can be installed in any BIG SPACE which is higher than 4.0 meters, not just a fan, but beautiful scenery.​
  • Innovative technology, low speed, less wear, maintenance-free, and long life.​

Space Ventilation

Ventilation is usually restricted in a tall and big spaces, and the exhaust fans can hardly work for the floors or corners of buildings where personnel and equipment are located. While HVLS fans can completely solve the problem by sending out a well-aligned wind in full space, cooperating with roof ventilators, improving air quality, and realize a healthy and comfortable working environment.
