We usually install a diffuser behind the fire exhaust fan, which can further convert kinetic energy into pressure energy, thereby increasing the power of the fan. So what are the main types of fire smoke exhaust fan diffusers?

1. A diffuser with an inner core of equal diameter and a dispersed outer cylinder. Its expansion effect is not as good as the previous one, but because of its simple layout technology, it is also suitable for situations where the diameter of the exhaust duct is larger than the outer diameter of the fan.

2. A diffuser with a dispersed outer cylinder and a converging core cylinder has better expansion effect due to the large addition of dispersed area. It is suitable for situations where the diameter of the exhaust duct is larger than the outer diameter of the fan.
