It appears you are describing a specific product model or specification for an industrial fan.
Here is the breakdown of what your description means, translated into technical specifications and a likely application scenario.
Translation of Your Description:
- 5-10 Series: This is the model series designation. In Chinese industrial fan naming conventions (e.g., 4-72, 9-19), the first number represents the pressure coefficient and the second the specific speed. A "5-10" series fan typically implies a specific aerodynamic design.
- Q345 High Strength Low Alloy Steel: This is the material.
- Q345 (now replaced by Q355 in newer Chinese standards) is a high-strength, low-alloy structural steel.
- Why use it? It offers about 1.5x the yield strength of standard A36 or Q235 steel. This allows the fan housing and impeller to be made thinner and lighter while still handling high pressures or heavy rotating masses, improving durability and reducing weight.
- Large Air Volume: This indicates the fan is optimized for high flow rate (CFM or m³/h) rather than high pressure.
- Low Noise: The impeller design (likely backward-curved or airfoil blades) and the rigid Q345 housing are designed to operate at lower decibel levels than standard industrial blowers.
- Centrifugal Blower: The type of fan. Air enters axially and is discharged radially (usually at 90 degrees).
What Is This Machine?
It is a heavy-duty industrial centrifugal fan designed for moving large quantities of air efficiently and quietly.
Key Technical Characteristics
| Parameter | Typical Value / Implication |
|---|---|
| Material Grade | Q345 (Yield ≥ 345 MPa). High strength, good weldability, wear-resistant. |
| Impeller Type | Likely Backward Inclined or Airfoil. These are the most efficient blade types for "large volume, low noise" applications. |
| Noise Level | Lower than standard fans (possibly 75-85 dB(A) depending on speed). |
| Typical Use | HVAC, ventilation, dust extraction, or general air movement where noise is a concern. |
Most Likely Applications
- HVAC Systems: Large commercial buildings, hospitals, or clean rooms requiring high air exchange with low noise pollution.
- Industrial Ventilation: Factories, warehouses, or tunnels where large volumes of air must be moved, but worker comfort (avoiding hearing damage) is a priority.
- Dust Collection Systems: Moving air through ducts and baghouses.
- Combustion Air: Supplying air to large burners or boilers.
Critical Question for You
To move forward with this specific fan, you need to know the Impeller Diameter (or "Size").
Chinese fan models are often specified by the Impeller Diameter in Decimeters.
- Example: A 5-10 No. 8C means an 800mm (31.5") diameter impeller.
- A 5-10 No. 12D means a 1200mm (47.2") diameter impeller.
Summary
You have described a robust, high-quality industrial fan (built with Q345 steel) for moving large air volumes with less noise than a typical sheet-metal fan. It is a premium choice for environments where both airflow performance and noise reduction are critical.
Are you looking to buy one, or are you trying to identify the parameters (size, motor HP, RPM) for a specific project?
