Based on the keywords you provided, I have reconstructed the most likely specification for a heavy-duty industrial fan. It appears you are referencing a Forced Draft (FD) or Induced Draft (ID) Fan for a boiler system.
Here is the breakdown of your keywords into a proper technical specification and product explanation:
Reconstructed Product Title:
440V / 10kV High-Temperature Boiler SA Fan (Forced/Induced Draft) Power Range: 11kW to 2000kW Lifespan: Long Lifespan (Designed for 20+ years) Airflow: 100,000 CFM (Cubic Feet per Hour)
Explanation of Your Keywords
Here is what each term means in an industrial context:
- 440V / 10kV: This refers to the voltage options.
- 440V: Standard low-voltage (LV) motor for smaller fans (typically < 200kW).
- 10kV (10,000 Volts): High-voltage motor for very large, high-power fans (typically > 500kW). This indicates a direct connection to medium-voltage power distribution, avoiding large step-down transformers.
- SA Fan: This likely stands for Single Aspiration or Steam Air Fan. Alternatively, it could be a typo for "SA" meaning Supply Air fan (used for combustion air in a boiler).
- Boiler: The application. This fan pushes air into the boiler combustion chamber (FD Fan) or pulls flue gas out (ID Fan).
- 11kW - 2000kW: The Motor Power Range. 11kW is the smallest entry point, while 2000kW (2 Megawatts) is the massive output needed for large power plant boilers.
- Long Lifespan: Implies the fan uses heavy-duty construction, bearing temperature monitoring, and erosion-resistant coating (hard facing) on impeller blades.
- 100,000 cfh (Cubic Feet per Hour): This is the Airflow Capacity.
- Correction: Industrial fans this size are often measured in CFM (Cubic Feet per Minute) .
- 100,000 CFM is a very large industrial fan (e.g., for a 50-100 MW boiler).
- If you truly mean 100,000 CFH (per hour), that is only ~1,667 CFM, which would be a very small fan for a small industrial boiler.
Likely Technical Specifications
If you are searching for or selling this product, here is the standard spec sheet:
| Specification | Value |
|---|---|
| Type | Centrifugal (usually Double Inlet/Outlet) |
| Application | Boiler Air Supply (FD) or Flue Gas Evacuation (ID) |
| Voltage | 440V (3-Phase, 60Hz) OR 10kV (10,000V, 3-Phase) |
| Power Range | 11 kW (15 HP) to 2000 kW (2,680 HP) |
| Airflow | Up to 100,000 CFM (100,000 ft³/min) |
| Static Pressure | Typically 10" - 40" w.g. (inches of water gauge) |
| Temperature | FD Fan: Ambient; ID Fan: Up to 400°F (200°C) continuous |
| Material | Carbon Steel (ST-37) or Corten Steel for high abrasion |
| Bearings | Heavy-duty spherical roller bearings with grease drain lines |
| Lifespan | 15-25 years (depending on maintenance and gas cleanliness) |
Common Use Cases
A fan with these specs (especially 2000kW and 10kV) is used in:
- Coal-Fired Power Plants
- Biomass Boilers (Large scale)
- Industrial Process Heating (Cement, Steel, Chemical plants)
Recommendation for Next Steps
If you are looking to purchase this, confirm these two things:
- Airflow Rate: Is it 100,000 CFM or 100,000 CFH? (CFM is 60x larger).
- Pressure: What is the static pressure requirement (e.g., 30 inches w.g.)? You cannot size a fan without pressure.
- Gas Type: Is it clean air (FD) or dirty flue gas (ID)? ID fans need wear protection.
If you meant a "SA Fan" as a specific brand or model code, please provide the manufacturer's name for a more accurate match.
