The main difference between low-pressure, medium pressure, and high-pressure centrifugal fans lies in their working pressure and application range. Specific distinctions can be made through the following aspects:
Working pressure:
Low pressure centrifugal fan: Its working pressure is usually below 1000 Pa, suitable for occasions with low pressure requirements, such as ventilation, air conditioning, etc.
Medium pressure centrifugal fan: Its working pressure is between 1000 Pa and 3000 Pa, widely used in industrial ventilation, air transportation and other environments that require high air volume.
High pressure centrifugal fan: The working pressure usually exceeds 3000 Pa, and can even reach tens of thousands of Pa. It is mainly used in applications that require high pressure output, such as blast furnace fans, gas transportation, and other fields.
Air flow range:
Low pressure fans usually have a large flow rate and are suitable for handling high air volumes. The flow rate of medium and high-pressure fans gradually decreases, but the pressure gradually increases.
Structural design:
Low pressure fans generally adopt a single-stage impeller design, with larger impellers and lower speeds.
Medium and high-pressure fans may adopt a multi-stage impeller design, with smaller impellers and higher speeds to meet the requirements of high-pressure output.
Application scenarios:
Low pressure fans are commonly used in conventional situations such as ventilation and air exchange;
Medium pressure fans are suitable for gas transportation with medium pressure requirements;
High pressure fans are widely used in gas compression, special industrial processes, etc.
In summary, low-pressure, medium pressure, and high-pressure centrifugal fans can be accurately distinguished through factors such as working pressure, flow requirements, and structural design.
