Fan inlet and outlet
Thread Content
Is it necessary to install expansion joints when the inlet and outlet temperatures of the fan are around 70 degrees?
Regardless of temperature, an expansion joint should be added
Expansion joints are generally installed at the inlet and outlet of fans, mainly to prevent vibration in the fans.
Expansion joints are needed when natural compensation is insufficient.
The fan I installed has flexible connections at both the inlet and outlet.
If shock absorption is required, it must be added. The function of the expansion joints at the inlet and outlet of the fan is to absorb shocks, not to provide thermal compensation.
It should be installed; the purpose of installing expansion joints at the inlet and outlet of the fan is mainly to absorb shocks and provide compensation. In terms of thermal compensation, it can be ignored if the temperature is not high.
