PMSM Fan used for Large Spaces
Target Price: $2,600.00
The PMSM Fan stands out for its remarkably low noise level, operating at approximately 36dB. This level of noise is even lower than the background noise typically found in tranquil libraries (39dB), making it an excellent choice for environments that require tranquility, such as libraries, schools, universities, and offices.
The PMSM Fan, including the large 24ft version, operates quietly without causing any disturbance. Its exceptional quietness is a testament to the diligent efforts of RTFANS and university professors in creating a fan that offers a peaceful and undisturbed environment.

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.
- High efficiency for low operating costs
- Compact design means low space requirements
- Robust grey cast iron housing
- High axial and radial load capacities enable safe operation
- Quiet running
- Application-specific versions
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.
Low Cost of Ventilation
RTFANS also makes a wide range of commercial and industrial ceiling fans. Commercial ceiling fans are smaller than industrial ceiling fans, and they can cover commercial areas easily. These fans are very quiet and have a noise level of around 40-42 dB. You can install these fans in restaurants, gyms, dining lounges, libraries, or any commercial place. There are different sizes available, so you can choose the right size according to your needs. Our fans are excellent to improve the air quality and ventilate a large area.
You can contact us to get an idea of the size of the fans. We can also help you select the right size.
