Fan soft connection is a flexible connection fitting between fan inlet and fan outlet, which is used for fan noise reduction and thermal compensation of fan pipe deformation

Scope of application: Fan soft connection is mainly used in the ventilation ducts of civil and industrial buildings, and the inlet and outlet of fans

Classification: Fan soft connection is divided into rectangular fan soft connection, circular fan soft connection, round and local soft connection
According to the material, it is divided into: Canvas fan soft connection, rubber fan soft connection, stainless steel fan soft connection, fabric fan soft connection
According to the pressure, it is divided into: positive pressure fan soft connection, negative pressure fan soft connection, fan soft connection, etc
Connection mode: the connection mode of fan soft connection is 1 Flange connection? 2
Welded connection? 3
Clamp connection is also called clamp connection

Uses and differences of various materials: Fan soft connection canvas material is used for the connection of ordinary fans, such as shopping malls, supermarkets, office buildings, civil houses and other air circulation fans
This kind of fan is generally installed indoors and is mainly used for air flow and dredging
There is no restriction of high temperature, corrosion and aging
It is the earliest and most basic Fan soft connection
In recent years, due to the requirements of fire protection, this kind of fan soft connection has gradually disappeared in the market, Because the fire prevention effect of canvas cannot meet the requirements, even if there is a kind of three proofing cloth, it cannot be used for 30 minutes at 280 ℃
Therefore, the silicon titanium fireproof soft connection solves this problem and is also an important branch of fireproof soft connection
The fan soft connection rubber material is used for high pressure, corrosion resistance and aging resistance
It is used in outdoor places and places with moisture in the air
This fan soft connection has good pressure resistance effect
There is also a fan soft connection with integrated rubber vulcanization, which has super waterproof performance, making up for the defects of the soft connection used outside the room
Fabric fan soft connection is mainly used in high-temperature places, and it can still be used when the temperature is as high as 1300 ℃

Parameters of fan soft connection: if the fan soft connection adopts flange connection, the use parameters should first ensure the flange hole spacing and hole diameter, followed by the pressure resistance grade
The soft connection pressure has a low pressure of less than 100KPA, and also has a high pressure of 25MPa design
