HVLS Fans

We provide One-Stop Ventilation and Cooling Solutions for large spaces, including Industrial Ceiling Fans, PMSM Fan and Commercial Ceiling fans.

HVLS Fan Instruction

A high-volume low-speed (HVLS) fan,also called an industrial ceiling fan, big fan, helicopter fan is a type of mechanical fan greater than 7 feet (2.1 m) in diameter. HVLS fans move air slowly and distribute a large volume of air at low rotational speed– hence the name “high volume, low speed.”

  1. HVLS Industrial Fan is a super larger energy-saving fan with a diameter of up to 7.3 meters (24ft);
  2. The airfoil Blade, which is developed with the advanced technologies and principle of aerodynamics;
  3. A power of 1.5kw or less, that move a High Volume(13,800m³/min) of air at a Low Speed and cools up to 1000 square meters;
  4. Produce a large scale of natural wind, which leads to the double functions of ventilation and Temperature cooling, as well as dehumidification;
  5. The Ideal solution is to ventilation and cools the air in a large area.

HVLS Fans Superiority

How effective HVLS fan is?

Take an example you will understand well: An area of 1000 square meters with a ceiling height of 10 meters, can be covered by one HVLS fan with a diameter of 24ft (7.3 meters), with 1.5 kW in power consumption, 828,000cmh airflow, at a noise level 43dB. Amazing, right?

HVLS Fans Superiority

Typical applications for HVLS fans fall into two classifications—industrial and commercial. HVLS Fan can be installed in any big space which is higher than 4m.

RTFANS hvls fans industrial ceiling fans

Industrial Ceiling Fans

RTFANS – HVLS industrial ceiling fans have 6 long (NASA-spirit superhard alloy) blades that move big volumes of air whereas rotating at a snail speed.
The big industrial ceiling fans combine the appearance of standard ceiling-mounted HVLS fans and have related industrial load structures, which can be used to improve the air quality in manufacturing plants and large-scale industrial environments.

RTFANS hvls fans commercial ceiling fans

Commercial Ceiling Fans

Extra-large commercial ceiling fans are specially designed for large commercial places and smaller industrial areas. There are completely different specifications from those used in most homes or offices. Applications of commercial HVLS ceiling fans are a gym, stadium, school hall, airport, hotel lobby, public area, small warehouses, workshop, etc. Installation height is from 4 to 6 meters.

RTFANS hvls fans PMSM fans

PMSM Fans

RTFANS use PMSM for low noise, high performance, and efficiency. It is to boot characterized by swish rotation over the full vary of a variable speed motor, full force management at zero speed, and fast acceleration and fastness. To achieve such management, we tend to use field-oriented management FOC techniques (also observed as vector control) for our PMSM.
