    I'm out there and I don't have any information at hand. The fan flow rate should be calculated according to your smoking area and the amount of smoke produced, which can be found in the dust removal and ventilation manual or relevant books. The duct data you provide can calculate its resistance along the way and local resistance, which is the basis for determining the wind pressure.

    Flow rate 2500m 3 h, there is no basis. In addition, there is a limit to the wind speed in the duct. In your case, you definitely have to use a centrifugal fan.
