Based on the parameters you provided (High Temperature, Stainless Steel, Centrifugal Blower, 3297~14287 m³/h), you are likely looking for a medium-to-large industrial backward-curved or radial blade centrifugal fan, typically used in kilns, ovens, drying systems, or thermal processing.
Here is a breakdown of what such a fan would typically look like and the specifications you should verify before purchasing.
Likely Application & Airflow Range
Your airflow range (3297 to 14287 m³/h) is common for:
- Ceramic or Tunnel Kilns: Air supply for combustion or cooling zones.
- Heat Treatment Furnaces: Forced air circulation.
- Industrial Ovens: Drying, curing, or powder coating.
- Exhaust Systems: Removing hot gases or fumes.
Conversion for reference: 14287 m³/h ≈ 8,400 CFM (Cubic Feet per Minute).
Critical Specifications (Must Confirm)
Based on your query, here are the specific details you need to specify to a supplier:
| Parameter | Typical Requirement for High-Temp Kiln | Your Input Needed |
|---|---|---|
| Airflow (Q) | 3297 ~ 14287 m³/h ✅ | (Already provided) |
| Static Pressure | 3,000 ~ 7,000 Pa (for kiln applications) | What is the system resistance? (High temp often requires high pressure) |
| Temperature | 200°C to 450°C (Standard High Temp) | Crucial: What is the maximum gas temperature? (e.g., 250°C or 400°C) |
| Material | Stainless Steel (SS304 or SS316L) | Good for corrosion & heat. SS310 is needed for >450°C. |
| Wheel Type | Backward Inclined (BI) or Radial Paddle Wheel | BI for efficiency; Paddle for dusty/harsh gas. |
| Motor Drive | Direct Drive or Belt Drive | Belt drive allows speed adjustment (changing airflow). |
Typical Fan Model Equivalent
A fan with this capacity (e.g., up to 4 m³/s at 2500-4000 Pa) often corresponds to a No. 4.5A to No. 6.3C size (Chinese standard model notation) or an IS 12155 equivalent in industrial frames.
Example Model Search Criteria:
- Type: High Temperature SS Centrifugal Fan (耐高温不锈钢离心风机)
- Power: Typically 4 kW to 15 kW depending on pressure requirements.
- Inlet Diameter: Approx. 400mm ~ 600mm.
- Outlet Area: Approx. 0.15 m² ~ 0.35 m².
Common Design Features for High Temperature
- Ducted Cooling System: A motor shaft cooling fan or impeller fins to prevent heat from traveling to the motor bearings.
- Bearing Selection: High-temp grease or water-cooled bearing housings for applications above 180°C.
- Expansion Joint: To accommodate thermal expansion of the fan housing.
- Variable Speed Drive (VFD): Recommended to adjust airflow between 3297 and 14287 m³/h without mechanical dampers.
Questions to Ask the Supplier
To ensure the fan meets your needs, ask:
- "At 7000 m³/h (midpoint), what is the static pressure capability?"
- "Is this fan rated for continuous operation at 350°C?"
- "What is the full-load motor current (amps) at 14287 m³/h?"
- "Does it come with a drain plug for condensation in kiln exhaust?"
- "Is the impeller dynamically balanced for high RPM operation?"
Next Step
If you can provide the required total pressure (in Pa or mmH₂O) and the maximum continuous temperature, I can help you refine the power rating, specific model numbers, or assist with a supplier search.
Would you like me to generate a Technical Data Sheet (TDS) template for this specification?
