A 2.2 KW AxALAL is a high-performance industrial ventilation solution designed to move large volumes of air at relatively low static pressure. Typically operating on 380V/400V three-phase power, this motor capacity strikes an optimal balance between energy efficiency and airflow output, making it ideal for warehouse ventilation, cooling towers, boiler exhaust, and general industrial air circulation. At Zibo Hongcheng Fans, we engineer these units with precision-balanced impellers and robust housings to ensure minimal vibration and maximum durability in demanding environments.
What Is a 2.2 kW Axial Fan and How Does It Work?
An axial fan moves air parallel to the shaft around which the blades rotate. Unlike centrifugal fans that change the direction of airflow by 90 degrees, axial fans push air straight through the unit. The “2.2 kW” specification refers to the power rating of the electric motor driving the impeller. This power level is significant in industrial applications because it provides sufficient torque to handle moderate resistance while maintaining high airflow rates, often ranging from 15,000 to 30,000 cubic meters per hour depending on the blade design and diameter.
The core mechanism involves an electric motor connected directly or via belts to a propeller-like impeller. As the impeller spins, it creates a pressure difference, drawing air in from one side and expelling it from the other. In industrial settings, the efficiency of this process is critical. A well-designed 2.2 kW axial fan minimizes energy loss due to turbulence and friction, ensuring that the electrical energy consumed is effectively converted into kinetic energy of the air.
Key Components of Industrial Axial Fans
- Impeller (Blades): Usually made from steel, aluminum, or reinforced plastic. The angle and shape of the blades determine the airflow volume and pressure capability.
- Motor: A 2.2 kW three-phase asynchronous motor is standard for heavy-duty use. It provides consistent power and can handle continuous operation.
- Housing/Casing: Protects internal components and directs airflow. Materials vary from galvanized steel for general use to stainless steel for corrosive environments.
- Bearings: High-quality bearings are essential to support the rotating shaft, reducing noise and extending the lifespan of the fan.
- Safety Guard: A mesh or grille installed on the intake or exhaust side to prevent accidental contact with moving blades.
Technical Specifications and Performance Data
When sourcing a 2.2 kW axial fan, understanding the technical parameters is vital for matching the equipment to your specific ventilation needs. While exact figures vary by model and manufacturer, the following table outlines typical performance characteristics for this class of industrial fans.
| Parameter | Typical Specification |
| Motor Power | 2.2 kW (3 HP) |
| Voltage | 380V / 400V / 415V (3-Phase, 50/60Hz) |
| Airflow Volume | 15,000 – 35,000 m³/h (varies by diameter) |
| Static Pressure | 200 – 600 Pa |
| Rotational Speed | 1450 RPM (4-pole) or 2900 RPM (2-pole) |

It is important to note that airflow and pressure are inversely related. As static pressure increases (due to ductwork resistance or filters), the airflow volume decreases. Therefore, selecting the right fan requires analyzing the system’s resistance curve. Zibo Hongcheng Fans utilizes advanced computational fluid dynamics (CFD) in our design process to optimize blade angles, ensuring that our 2.2 kW models deliver peak efficiency within their intended operating range.
Common Applications for 2.2 kW Axial Fans
The versatility of the 2.2 kW power rating makes these fans suitable for a wide array of industrial and commercial applications. They are particularly effective in scenarios requiring high air exchange rates rather than high-pressure delivery.
1. Warehouse and Factory Ventilation
Large industrial spaces accumulate heat, fumes, and stagnant air. A 2.2 kW axial fan can be mounted on walls or roofs to create powerful cross-ventilation. This helps maintain a comfortable working environment and removes hazardous airborne particles, complying with occupational health and safety standards.
2. Cooling Towers and Heat Exchangers
In HVAC systems and industrial cooling processes, axial fans are used to dissipate heat from water or glycol loops. The high airflow capacity of a 2.2 kW unit ensures efficient heat transfer, preventing overheating of machinery and maintaining process stability.
3. Agricultural and Greenhouse Air Circulation
Proper air circulation is crucial in agriculture to control humidity and temperature. These fans help prevent mold growth and ensure uniform distribution of CO2, promoting healthier crop yields. The robust construction of industrial-grade fans ensures they can withstand the humid and sometimes corrosive conditions of agricultural environments.
4. Boiler and Furnace Exhaust
While high-temperature specialized fans are required for direct exhaust, 2.2 kW axial fans are often used in the surrounding ventilation systems of boiler rooms to remove ambient heat and provide combustion air intake. Zibo Hongcheng Fans offers specialized models with heat-resistant coatings for such demanding proximity applications.
5. Tunnel and Underground Mining Ventilation
Given our expertise in mining axial flow fans, Zibo Hongcheng Fans designs units that can handle the rigorous demands of underground ventilation.

Selection Guide: How to Choose the Right 2.2 kW Axial Fan
Choosing the correct fan involves more than just matching the motor power. To ensure optimal performance and longevity, consider the following factors during the selection process.
1. Airflow and Pressure Requirements
Calculate the required air changes per hour for your space. Determine the static pressure loss caused by ducts, filters, louvers, and bends. Select a fan whose performance curve intersects your system’s resistance curve at the desired airflow point. Operating a fan far from its best efficiency point can lead to excessive noise and premature motor failure.
2. Material Compatibility
The environment dictates the material. For standard workshops, galvanized steel or carbon steel with paint is sufficient. However, for chemical plants or coastal areas with high salinity, stainless steel (such as 304 or 316L) or fiberglass-reinforced plastic (FRP) is necessary to prevent corrosion. Zibo Hongcheng Fans specializes in corrosion-resistant fans, ensuring longevity in harsh conditions.
3. Temperature and Media Characteristics
Consider the temperature of the air being moved. Standard motors are rated for ambient temperatures up to 40°C. If the air is hotter, you may need a motor with higher insulation class (Class H) or a cooling extension shaft. Additionally, if the air contains dust or particulates, choose a fan with sealed bearings and possibly a self-cleaning blade design.
4. Noise Constraints
If the fan is installed near workstations or residential areas, noise control is paramount. Look for fans with aerodynamically optimized blades and low-vibration motors. Installing silencers or using flexible connections can further reduce noise transmission. Our engineering team can provide noise data sheets to help you make informed decisions.
5. Installation and Maintenance Access
Ensure there is adequate space for installation and future maintenance. Wall-mounted fans require sturdy structural support, while roof-mounted units need weatherproof curbs. Consider the ease of accessing the motor and bearings for regular lubrication and inspection.
