Based on your search query, it appears you are looking for a high-power (22kW / ~30HP), high-volume, industrial-grade centrifugal fan made from carbon steel. This type of equipment is typically used in heavy-duty applications like material handling, dust collection, or forced draft systems.
Here is a breakdown of what you are likely searching for, key specifications, and typical applications.
What the Description Means
- Carbon Steel: Indicates the fan housing and impeller are made from mild steel (e.g., Q235 or similar). This is suitable for clean air, fumes, wood chips, light dust, or moderate temperatures. For corrosive or highly abrasive materials, stainless steel or special coatings would be needed.
- Large Air Flow: This implies a fan designed for high volume (m³/h or CFM) rather than extremely high pressure.
- 22kW (22 Kilowatt): This is the motor power (approximately 30 HP). This is a large industrial motor, usually requiring a 415V (or 380V) three-phase power supply. It often requires a star-delta or soft starter.
- Blower / Centrifugal Fan: Refers to the type of fan. Based on "Large Air Flow," you are likely looking for a Backward Curved (high efficiency, stable) or Forward Curved (high volume, lower pressure) centrifugal fan. An Airfoil blade design is also possible for maximum efficiency.
- Centrifugal: Air enters axially (along the shaft) and exits radially (out the side).
Key Specifications to Look For
When sourcing this fan, you should ask the supplier for these specific parameters:
| Parameter | Typical Value / Range (for a 22kW Carbon Steel Fan) | Notes |
|---|---|---|
| Motor Power | 22 kW (30 HP) | Usually 2-pole (2900 RPM) or 4-pole (1450 RPM). 2-pole for high pressure, 4-pole for massive volume. |
| Airflow (Max) | 20,000 m³/h to 80,000 m³/h (11,700 CFM to 47,000 CFM) | Depends heavily on pressure and fan speed. |
| Static Pressure | 2,000 Pa to 5,000 Pa (8" to 20" w.g.) | "Large Air Flow" fans are often in the lower to mid-pressure range. |
| Impeller Type | Backward Inclined (BI), Airfoil (AF), or Forward Curve (FC) | BI/AF: Best for high efficiency and non-clogging. FC: Best for high volume at lower pressure, but less efficient. |
| Temperature Range | -20°C to +120°C (Standard) | Max could be higher with special designs (e.g., 250°C). |
| Inlet/Outlet Size | DN400 to DN800 | Large airflows require large duct connections. |
| Material | Q235 Carbon Steel (Housing & Impeller) | Standard industrial grade. |
Common Applications for This Fan
- Industrial Dust Collection: Moving air through large baghouse filters or cyclones for woodworking, cement, or metalworking plants.
- HVAC / Ventilation: Supplying or exhausting air for large factories, warehouses, or commercial buildings.
- Pneumatic Conveying: Moving light materials (pellets, grains, paper scraps) through ducts.
- Kiln & Boiler Draft: Induced Draft (ID) or Forced Draft (FD) fans for medium-sized industrial furnaces.
- Air Pollution Control: For scrubbing or filtering large volumes of industrial exhaust.
Where to Find It (Sourcing)
You can search for these using the following keywords on Alibaba, Made-in-China, or global industrial fan manufacturers:
- "22kW centrifugal fan carbon steel"
- "High volume blower 30HP"
- "Industrial backward curved fan 22000 CFM"
- "Dust collector fan 22kw"
- "Carbon steel airfoil fan 20000 m3/h"
Major Brands / Manufacturers to look for:
- Global: New York Blower, Howden, Greenheck (USA/Europe)
- Asian (Popular on sourcing sites): Yi Fan Blower (Your provided search), JINFAN, Zibo Decent, Changsu Tongda, or generic "High Quality Carbon Steel Centrifugal Fan" from Chinese manufacturers.
Important Note: Because this is a 22kW unit, it is heavy (often > 500 kg) and requires three-phase industrial power (380-415V) . You will likely need an electrical contractor to install the starter and connect it.
Before You Buy
- Confirm RPM: A 22kW motor can drive a 2-pole (2900 RPM) or a 4-pole (1450 RPM) fan. The RPM drastically changes the pressure and volume.
- Check Noise Level: Large fans are very loud. You may need silencers or acoustic enclosures.
- Ask for a Fan Curve: The manufacturer must provide a performance curve showing airflow vs. static pressure at the operating point.
If you can provide more details about your specific application (e.g., "clean air venting" vs. "conveying wood chips"), I can help narrow down the exact fan type (Backward Curved, Radial Blade, etc.).
