8-09 High Pressure
Centrifugal Fan
The 8-09 high pressure centrifugal fan is designed for cupola furnace blowing, melting furnace air supply, forging furnace ventilation and industrial gas conveying systems that require high total pressure.
Before selection, QIYUE FAN reviews airflow, pressure, furnace duty, gas temperature, dust content, motor power, outlet angle, rotation direction and installation layout.
High Pressure Air Supply for Furnace and Gas Conveying Duty
The 8-09 fan is not a general workshop ventilation fan. It is selected when the system resistance is high and the process requires stable pressure, such as cupola furnace blowing, melting furnace air supply, forging furnace ventilation and non-corrosive industrial gas conveying.
Its selection should start from the required pressure and process duty. For furnace blowing, the fan must match combustion air demand, duct resistance, furnace condition, motor power and continuous operation requirements.
The standard conveyed medium should be non-corrosive, non-flammable and free from viscous substances. If the gas contains abrasive dust, high temperature or corrosive components, the fan series and material configuration should be reviewed before quotation.
Where the 8-09 Fan Works in a Furnace Air Supply System
In furnace blowing applications, the fan must deliver air against process resistance. The air path, pressure loss and outlet direction should be reviewed before production.
Clean air enters the fan inlet.
Impeller provides high total pressure.
Duct route and outlet angle affect loss.
Stable air supply supports combustion or conveying.

8-09 High Pressure Performance Groups
The following table is a simplified reference for early communication. Detailed model selection should be confirmed according to the real operating point and working medium.
| Fan Group | Speed | Airflow Direction | Pressure Character | Selection Note |
|---|---|---|---|---|
| 6.8A | 2900 r/min | 675-2295 m³/h | High pressure small airflow | Cupola and compact furnace blowing. |
| 7.1D | 2900 r/min | 1075-2919 m³/h | Stable pressure output | Review motor power and outlet direction. |
| 8D / 8.5D | 2930-2950 r/min | 1341-4560 m³/h | Higher airflow under high pressure | Used for furnace or gas conveying duty. |
| 9D | 2950 r/min | 1591-6049 m³/h | Upper range pressure class | Check foundation, electrical capacity and operation duty. |
Note: The 8-09 fan should not be selected only by fan number. Send airflow and pressure requirements before quotation.
