What is a high-pressure centrifugal fan?
High-pressure centrifugal fans, also commonly known as blower fans, are radial fans that produce high pressure at low-to-medium flow rates. Values such as 250–260 mmSS in product names indicate the pressure level of these fans. They are used in long, high-resistance duct runs, for supplying combustion air to burners and furnaces, in blacksmith and foundry furnaces, in pneumatic material conveying, and in systems with high filter resistance.
Applications
- Combustion air supply to furnaces, burners, and kilns
- Light material conveying in pneumatic transfer lines
- Long exhaust ducts with multiple elbows
- High-resistance filter and scrubber systems
- Pressurized air jets for drying and cooling processes
Selection criteria
When selecting a high-pressure fan, the system's total pressure drop and required flow rate must be determined together. The fan's actual operating point should be the intersection of these two values on the performance curve. High pressure makes duct and connection sealing more critical; leaks cause flow rate loss. Motor power, speed, and power supply must be selected to match the facility's infrastructure. Since high-pressure fans generally operate louder, the need for a silencer should be evaluated.
Installation and maintenance
The fan must be secured to a solid base using anti-vibration mounts and flexible connections. A protective guard should be fitted to the inlet to prevent foreign objects from reaching the impeller. Since imbalance in high-speed impellers can quickly damage bearings, blade cleaning and bearing inspection should be performed regularly.
Frequently asked questions
What does "blower fan" mean?
It is a common term used for high-pressure centrifugal fans.
Does a high-pressure fan consume more energy?
Since it produces higher pressure at the same flow rate, motor power is generally higher.
Which fan for a furnace?
High-pressure fans are preferred for supplying combustion air in furnace and burner applications.
How can blower fan noise be reduced?
A silencer, flexible connections, and anti-vibration mounts reduce noise. Positioning the fan away from areas where people work is also an effective method.
Why do duct leaks matter?
In high-pressure systems, leaks noticeably reduce the flow rate.
What if lower pressure is sufficient?
Medium-pressure fans may be a more economical solution.
What motor does a high-pressure fan use?
Depending on the model, a single-phase or three-phase motor is used. The HP value in product names indicates the motor power.
