An Introduction to the 120x120x25mm AC Axial Fan (Ball Bearing, 110-380V)

Dependable thermal management is a critical factor in upholding the peak performance and long service life of electrical and electronic hardware. The 120x120x25mm AC axial fan, created with a sturdy build and precision engineering, serves as an exemplary solution for applications that necessitate consistent ventilation, quiet functionality, and enduring resilience. With a compact profile of 120mm by 120mm and a slender 25mm depth, this fan is tailored for deployment in a diverse range of industrial and commercial environments.

Architecture and Build Quality

This axial fan is fashioned with a solid and compact square chassis, constructed from high-quality metal to ensure exceptional mechanical integrity, heat tolerance, and protection against corrosion. Its design incorporates four mounting apertures at the corners for secure and flexible installation within enclosures, control boxes, power distribution cabinets, and electronic housings. The fan's blades are aerodynamically optimized to deliver high airflow with minimal drag and noise, which contributes to both its power and acoustic efficiency.

The overall measurements of 120x120x25mm achieve an ideal balance between space-saving integration and effective air circulation. The unit comes with a wire lead approximately 300mm long, providing ample flexibility during its electrical setup.

Bearing Mechanism

This fan utilizes a ball bearing system, which is celebrated for its remarkable dependability and extended lifespan. When compared to fans with sleeve bearings, ball bearing mechanisms present several key advantages, including:

• A longer operational duration, especially within high-temperature settings.

• Superior performance in both vertical and horizontal mounting positions.

• Reduced friction and smoother rotation, which results in more stable operation.

• Less degradation over time, which minimizes maintenance needs.

These characteristics make the ball bearing system particularly well-suited for industrial uses and for systems that function continuously over prolonged periods.

Electrical Versatility

This AC axial fan is engineered for a wide spectrum of input voltages, supporting 110V, 220V, and 380V AC at both 50Hz and 60Hz frequencies. This broad voltage support ensures adaptability in deployment across global power standards and various equipment designs.

Regardless of the specific voltage model, the fan maintains uniform performance characteristics, which guarantees ease of replacement or integration across different systems. The availability of multiple voltage configurations makes it an optimal choice for international applications or for facilities with mixed-voltage infrastructures.

Performance Specifications

The fan is designed to function at a consistent velocity of 2700 RPM (Revolutions Per Minute) across all voltage models. This high-speed operation facilitates efficient heat dissipation and steady airflow. Below is a summary of key performance data:

• Airflow: The unit produces a robust airflow of 66.1 CFM (Cubic Feet per Minute), equivalent to 1.87 m³/min, which is ample for cooling moderately dense electronic assemblies and enclosures.

• Static Pressure: With a static pressure rating of 3.56 mmH₂O (or 0.14 inchH₂O), the fan can sustain air movement even against backpressure or in environments with restricted airflow. This makes it suitable for use with filters or within tightly packed systems.

• Noise Level: Operating at a low acoustic level of 38 dBA, the fan is exceptionally quiet for its airflow capacity, making it appropriate for noise-sensitive settings like offices, laboratories, and communication rooms.

• Power Consumption:

• 110V version: 16.5 Watts, 0.15 Amps

• 220V version: 19.8 Watts, 0.09 Amps

• 380V version: 15.2 Watts, 0.04 Amps

These low power ratings make the fan energy-efficient, which reduces operational costs while preserving thermal performance.

Common Applications

Thanks to its adaptable size, electrical compatibility, and dependable ball bearing design, the 120x120x25mm AC axial fan is appropriate for a wide variety of uses. Typical applications include:

• Industrial Control Panels: Supplying consistent airflow to cool sensitive hardware like PLCs, inverters, and power supplies.

• Telecommunication Equipment: Ensuring network switches, routers, and data hubs operate within their temperature limits.

• Household Appliances: Integrated into devices such as air purifiers, ovens, or refrigeration units for better heat management.

• Power Distribution Cabinets: Preventing the overheating of circuit breakers and electrical distribution hardware.

• Medical and Laboratory Devices: Providing quiet, reliable operation for delicate instrumentation.

Durability and Upkeep

Weighing approximately 372 grams, this fan is lightweight yet sturdy in its construction. The metal frame and ball bearing mechanism contribute to its long operational life and resilience under continuous use. Maintenance requirements are minimal due to the sealed bearing design, and the unit is resistant to dust ingress and moderate environmental contaminants. For even more severe environments, the fan can be paired with filters or protective guards to help extend its lifespan and maintain consistent performance.

Installation and Integration

The installation of this fan is straightforward, due to its standard measurements and mounting layout. It can be mounted using common screws or brackets into any matching cutout or frame. The 105mm hole-to-hole spacing ensures compatibility with most industrial and commercial fan mounts. The 300mm wire lead permits flexible routing and secure electrical connections. It supports a two-wire AC connection, which simplifies integration into most AC power systems.

Environmental Adaptability

Designed to function across a broad temperature range, this fan can be safely utilized in settings where ambient temperatures fluctuate or reach elevated levels. The ball bearing system is especially advantageous in this regard, as it can handle higher operational temperatures without significant performance loss.
