Fan selection needs to consider the following elements: air volume and air pressure,

Air volume refers to the volume of air passing through the fan per unit time, usually in cubic meters per hour (m³/h) or cubic feet per minute (CFM) as a unit. According to the specific application requirements, determine the required air volume range, and then select the fan.

Static pressure: Static pressure refers to the pressure difference that the fan can generate, which determines the ability of the fan to overcome pipeline resistance or deliver air volume. According to the specific pipeline layout and pressure requirements, determine the required static pressure range, and select a fan with corresponding static pressure capacity. It should be noted that the selection of the centrifugal fan also needs to consider the details and requirements of the specific application, such as gas characteristics, temperature, humidity, etc.

Although the motor power can provide a certain reference, it cannot directly calculate the air volume and air pressure of the centrifugal fan, so it is impossible to accurately answer the air volume of the 200kW fan. In order to determine the air volume and air pressure of the centrifugal fan, it is usually necessary to conduct a fan performance test or rely on the performance curve and data provided by the manufacturer for calculation. These tests and data can provide accurate air volume and air pressure indicators to help select a suitable centrifugal fan.
