The methods to deal with the noise of the fan include installing sound-deadening equipment, wrapping a sound-deadening coat, installing a sound-deadening room and so on.

1. Install silencing equipment

You can install silencing accessories such as silencers at the fan mouth, which will have a good noise reduction effect on the fan.

2. Wrapping a sound-proof coat

Wrapping a sound-proof cover on the outside of the fan is equivalent to putting a piece of clothing on the fan, which has a certain noise reduction effect.

3. Install a silencing room

When the noise of the fan is relatively high, a special silencing room can be set up. Putting the fan in the silencing room can prevent the noise emitted by the fan from spreading to other spaces. If the space is limited, the soundproof cover can also be used as a silencing room.

4. Change the type of fan

There are many types of fans on the market, some of which have mute effect. For example, fans made by working principles such as high-speed centrifugation and magnetic levitation have little noise, but the price will be slightly more expensive, so individuals can consider economic strength to buy them.

Common types of fans:

1. Centrifugal fans: Centrifugal fans work by the principle of centrifugal force. After starting, the airflow will enter the blade position, be compressed by the rotation of the blade, and then flow in the radial direction.

2. Axial fan: This type of fan, whose airflow flows in the axial direction, has good advantages in terms of flow rate, volume and pressure head compared with centrifugal fans, but there are some restrictions on the use occasions, so it is not suitable for places with heavy dust and corrosive gases.

3. Oblique flow fan: It is modified on the basis of axial flow fan, and its pressure coefficient will exceed that of axial flow fan and flow coefficient will exceed that of centrifugal fan.
