DB (decibels) is a unit used to measure sound, which can indicate the intensity of sound. 0 dB represents the minimum measurable sound, what is the equivalent of 38 dB sound? A sound of 38 dB can be compared to the background noise of a washing machine or refrigerator, which is enough to make people feel it, but not enough to interrupt the ongoing conversation. For example, the sound of a mosquito flying by is about 40 decibels, and 38 decibels is equivalent to the volume of whispering in your ear.
When facing a large fan, we cannot ignore the important factor of noise. In the large fan market, excessive noise is a concern for many users.
To solve the noise problem of ultra large industrial fans, the first step is to find the source of the noise from ultra large industrial fans. Generally speaking, the noise of ultra large industrial fans mainly comes from two aspects: the fan blades and the motor.
The first reason for generating noise is that the fan blades drive the air to produce airflow sound, which is commonly understood as wind noise.
The fan uses advanced technology and materials to carefully design the shape and angle of the fan blades. The streamlined variable cross-section blade design tilts upwards by 0-1.5 ° to greatly reduce noise generation. Allow users to enjoy a quiet and comfortable working environment.
The second aspect that generates noise is the motor. The ultra large industrial fan using a reducer motor generates power through gear rotation, which also produces significant noise during the rotation process. Decibel levels are above 50-90 decibels. Therefore, when choosing, try to choose high-quality branded motors. Of course, currently the ultra large industrial fans of gear reduction motors have gradually been replaced by the ultra large industrial fans of permanent magnet motors. Permanent magnet direct drive motors should use electromagnetic induction to generate power without the need for gear rotation. Therefore, the noise is relatively low, and the normal usage noise is within 30-50 decibels.
The fan adopts PMSM permanent magnet synchronous motor, with an ultra-low volume of 38db and a very soft sound.
Fans not only perform well in noise control, but their excellent ventilation effect cannot be ignored. Our fans are equipped with powerful motors and professionally designed blades that can quickly expel hot and polluted air. At the same time, the soft wind generated by the fan blows on the human body, promoting sweat evaporation and cooling the body, bringing a cool and comfortable feeling. This cooling effect can usually reach 5-8 ℃, giving people a comfortable experience like natural wind.
We have always been committed to creating a high-quality working environment for our customers through continuous technological innovation, aiming to improve air quality while reducing work related factors to ensure that employees can fully devote themselves to work and enjoy a comfortable and healthy environment.
