PMSM Fan used for Large Spaces

Ceiling fans for horse barns and cattle farms are the solution to all problems that are caused by improper ventilation.

PMSM Fan
We have always been in research to improve the quality and performance of our fans. Thus, the researcher’s team has made PMSM technology with the collaboration of Tsinghua University and Zhejiang University. The technology has a permanent magnet synchronous motor (PMSM), which performs better than other technologies.
  • Choose from 8ft-24ft in diameter and above 6m+ space options;
  • Six aluminum airfoils with winglets and safety constraints;
  • Industrial-grade motor with sealed helical gearbox for smooth operation and durability;
  • Installation to I-beams, joists, solid beams, and purlins;
  • Robust safety features keep workers cool and safe;
  • Broad airflow coverage improves your space's existing HVAC efficiency.

Core Technology

RTFANS has made a wide range of sizes for the PMSM fans to cover large spaces. The fan is available in five models that have a diameter in the range of 12ft-24ft. The airflow of these fans ranges from 7,500 to 15,000 cubic meters per minute, depending on the size of the fan. They can cover an area of around 630-1,500 square meters. Thus, you can easily select the right size of the fan according to your area. You can install the fan in any area that has a ceiling height of more than 4.5 meters. PMSM fans can work better for large spaces.

Super Quiet

The best thing about the fan is its very low noise level. There is no doubt that HVLS fans are quiet, but PMSM fans are quieter. The noise level of PMSM fans is around 36dB, which is less than the noise of a quiet library (40dB). Even the large fans that are 24ft long are also quiet with a noise level of 36dB. Since these fans are quiet, they are also perfect for quiet spaces like libraries, schools, colleges, offices, etc. The fan does not disturb you at all. In most cases, you will not even notice the noise of the fan. These super quiet fans are due to the hard work of RTFANS and university professors.

PMSM Fan

Large Space of Action

PMSM fans have a larger space of action as compared to other technologies. These fans can cover more areas, which indicates high performance. The largest fan of 24ft diameter has a maximum space of action of 1,800 square meters, which is more than a simple HVLS fan. It is because of the high airflow. The 24ft PMSM fan can provide 15,000 cubic meters per minute, while a simple HVLS fan of the same size has an airflow of 13,500 cubic meters per minute at the same rotational speed. Thus, you can install fewer units in your large space. PMSM fans are perfect for large spaces where you need constant ventilation to improve air quality. Due to high airflow, they cover a very large area and throw a well-aligned breeze to every corner.

Less Weight

The running cost of PMSM fans is less than all PMSM fans. They use almost 1/10 of the electricity used by air conditioning systems. With these fans, you can cover a large area and improve air quality. These fans use only 1.5kW motors to spread the air in a large area. They provide an excellent cooling effect and a comfortable environment at a very low running cost.
