Introduction
The High Pressure Centrifugal Fan is a centrifugal fan designed to produce a higher static pressure than a standard centrifugal fan. It moves air or gas by converting the rotational energy of the impeller into a higher pressure, and is suitable for systems that require strong airflow to overcome resistance, such as ducts, filters or complex ventilation networks.
Features
Excellent High-pressure Performance
The High Pressure Centrifugal Fan adopt a multi-stage impeller series design, with a single-stage pressure increase of up to 8000Pa and a maximum working pressure of 25000Pa for three-stage series. The impeller is precisely dynamically balanced and calibrated, and the vibration value is controlled within 2.0mm/s under extreme pressure conditions, which is 30% lower than the industry standard.
High-efficiency Operation Characteristics
Our products are equipped with backward-facing airfoil blades, with an aerodynamic efficiency of 82%, which is 15-20% higher than ordinary forward blade fans. Tests at the 10000Pa operating point show that the isentropic efficiency exceeds 75%, which is 8% higher than similar products.
Wide Temperature Range Adaptability
The operating temperature range of our products is -30℃ to 450℃. The high-temperature products are made of heat-resistant steel. They can run continuously for 1000 hours at 400℃ with a performance degradation of less than 3%.
Applications
Industrial Ventilation System
In large factories, tunnels, underground garages and other places, high-pressure centrifugal fans are used for forced exhaust and fresh air delivery.
Dust Collection and Dust Removal Equipment
High-pressure fans can provide sufficient wind pressure to drive dust collectors, such as bag dust collectors, electrostatic precipitators, etc., to achieve effective collection and purification of industrial dust and flue gas, and are widely used in metallurgy, mining, cement, electricity and other industries.
Combustion and Combustion-supporting System
A large amount of high-pressure air is required during the combustion process of boilers and kilns to ensure full combustion of fuel.
Conveying and Pneumatic Conveying System
Applicable to pneumatic conveying of particles and powders, such as grain, chemical raw materials, plastic particles, etc. The fan needs to provide high-pressure air volume to support the long-distance conveying of materials.

FAQ
Q: What is a high pressure centrifugal fan?
A: A high pressure centrifugal fan is a type of fan designed to generate high static pressure by accelerating air or gas through centrifugal force. It is commonly used in systems requiring airflow against significant resistance, such as ductwork or filters.
Q: What are the main advantages of high pressure centrifugal fans?
A: They provide strong airflow at high pressures, making them suitable for long duct runs and high-resistance systems. They offer stable performance, durability, and can handle various air contaminants when built with appropriate materials.
Q: In which industries are high pressure centrifugal fans typically used?
A: They are widely used in HVAC, industrial ventilation, dust collection, power plants, chemical processing, and manufacturing environments where high-pressure airflow is necessary.
Q: How do you select the right high pressure centrifugal fan?
A: Selection depends on required airflow (CFM), static pressure, temperature, gas composition, installation space, and noise requirements. Proper sizing and material choice are essential for performance and longevity.
Q: What maintenance is required for high pressure centrifugal fans?
A: Routine maintenance includes inspecting and cleaning fan blades, checking bearings and belts (if applicable), lubricating moving parts, and monitoring vibration and noise levels to ensure reliable operation.
