Noise level of HVLS industrial large fan

The noise level of HVLS (High Volume, Low Speed) industrial fans is an important parameter that users are very concerned about when selecting and installing fans. The HVLS industrial fans produced by Air21xx perform well in noise control.

Noise Level

The design of HVLS fans focuses on low speed and high air volume, which typically means that they can maintain relatively low noise levels while providing strong airflow. According to the information from Air21xx Environmental Technology, their HVLS industrial fans have a noise level of only 45 decibels (dBa) in a laboratory environment. This noise level is equivalent to a quiet office environment or a soft conversation, which is acceptable for the workplace.

Noise Control Technology

To achieve low noise, HVLS fan manufacturers usually adopt a series of design and technical measures. For example, using high-quality reduction motors and precision gear systems can reduce mechanical noise. In addition, the blade design of the fan also affects the noise level, and streamlined blades can reduce the noise generated by air flow.

Application Scenario Considerations

When selecting HVLS fans, noise level is an important consideration, especially in noise-sensitive environments such as hospitals, schools, or commercial spaces. Air21xx Environmental Technology’s HVLS fans are capable of providing effective air circulation while maintaining low noise, making them suitable for use in various industrial and commercial settings.


Overall, HVLS industrial fans are designed with special consideration for noise control to ensure that they do not interfere with the work environment while providing good ventilation effects. The HVLS fans from Air21xx Environmental Technology are an example; their noise test results in a laboratory environment indicate that these fans can operate in a relatively quiet environment, providing users with a comfortable working environment. When choosing HVLS fans, the noise level of the fan should be considered, and the right choice should be made based on the specific application scenario and environmental requirements.
