​Industrial Centrifugal Fan Manufacturer Shares Fan Selection Guidelines

Industrial Centrifugal Fan Manufacturer Shares Fan Selection GuidelinesIndustrial Centrifugal Fan Manufacturer Shares Fan Selection: Five Key Factors Influencing Fan Selection; Industrial centrifugal fan manufacturers define airflow volume as the product of air velocity v and the cross-sectional area f of the fan duct. Industrial centrifugal fan manufacturers can use an anemometer for precise measurement, making airflow volume calculation straightforward. Airflow volume can be directly calculated using the formula Q=VF. Industrial centrifugal fan manufacturers determine the number of fans required by calculating the air volume needed for the workshop based on the air changes per hour for the selected room, then calculating the number of fans accordingly. Industrial centrifugal fan manufacturers calculate the external residual pressure = total fan pressure - resistance of each processing section in the air cabinet. Return duct resistance is generally calculated at 7~8 Pa/m, with 90-degree elbows calculated at 10 Pa per piece. 1. For heat or steam exhaust, prioritize roof exhaust fans whenever possible. 2. When heating, cooling, or supplying fresh air, position heated or cooled airflow near personnel locations. Duct fans or sidewall fans are thus commonly used. 3. For fire smoke exhaust, prioritize roof ventilators or suspended ductwork. Duct fans are therefore frequently employed. Note: Maximize natural airflow (fan placement and configuration should be optimized). Fan selection for specific applications
