The 10-24 high-pressure centrifugal fan is designed for forging-furnace air supply, sulfuric-acid furnace-bottom ventilation, industrial forced draft, process air and selected dry-material conveying duties where the system requires high pressure.
The documented series covers No.6.8 to No.8.5, with airflow from 7,210 to 20,178 m³/h and total pressure from 11,920 to 19,964 Pa at a reference fan speed of 2960 r/min.
Final fan size, motor, rotation and discharge angle should be confirmed from the actual duty point and installation requirement.
High Pressure for Furnace Forced Draft and Industrial Air Systems
The 10-24 series is a pressure-oriented centrifugal fan for applications where ordinary ventilation fans cannot provide sufficient pressure. The original catalogue lists forging-furnace air supply, sulfuric-acid furnace-bottom ventilation, general high-pressure forced draft and material conveying.
The conveyed medium should generally be non-corrosive, non-self-igniting and non-sticky. Catalogue guidance states that medium temperature should generally not exceed 80°C and dust or hard-particle content should not exceed 150 mg/m³.
For combustion-air projects, review the Industrial Forced Draft Fan System. Final selection should then be confirmed from airflow, total pressure, medium, temperature, motor, rotation, discharge angle and installation space.

Rotation and Discharge Angle Are Separate Parameters
CW / CCW
Rotation identifies the impeller turning direction. Confirm the project viewing convention on the approved drawing before production.
0° / 90° / 180°
Discharge angle describes the physical outlet position around the fan casing. It is not the same as fan rotation.

What airflow range does the 10-24 cover?
The documented series covers 7,210 to 20,178 m³/h.
What total pressure range is documented?
The published operating points cover 11,920 to 19,964 Pa total pressure.
What fan sizes are included?
No.6.8, 7.1, 7.4, 8 and 8.5.
What is the reference fan speed?
The documented performance table is based on 2960 r/min.
Is discharge angle the same as rotation?
No. Rotation identifies impeller turning direction, while discharge angle identifies outlet position. The documented discharge positions are 0°, 90° and 180°.
Can QIYUE supply motors for overseas voltage and frequency?
Yes. Motor voltage, frequency, phase and protection can be matched to the project requirement after the fan operating point is confirmed.
Send the Required Airflow and Pressure
Send airflow, total or static pressure, medium temperature, gas or material condition, voltage, frequency, rotation, discharge angle and quantity. QIYUE FAN can review the appropriate 10-24 size, motor and installation configuration.
