Organic waste gas is purified through adsorption treatment; a fan with a flow rate of 2000 and a pressure rating of 4000 Pa is selected. Why is the actual flow rate only around half of that, and unable to reach the desired level? What aspects might be the problem? The air duct flow velocity is also around 8
The system’s pressure loss is too high, exceeding the design value.
What is the outlet pressure of the fan? For a model with a volume flow rate of 2000 cubic meters, when the total pressure of the fan is 4000 Pa, if this pressure exceeds that value, the volume flow rate may not reach 2000 cubic meters
If the total pressure of the fan is 4000 Pa, it refers to the inlet pressure plus the outlet pressure, right? What are typical values for the inlet pressure and the outlet pressure?
Pipe resistance, recalculate it； Under normal circumstances, it is caused by insufficient fan pressure.
The air volume of a fan is generally measured under standard conditions at 20°C. When installed in a process system, it may be affected by the pressure differences before and after the fan. It is recommended to check the pressure at the fan’s inlet and outlet, calculate the value using the fan’s operating curve, or provide this information to the manufacturer so that they can carry out a verification.
