A High-Efficiency Cooling Unit: The 120x120x38mm AC Axial Fan with Ball Bearings

The 120x120x38mm AC axial fan is a resilient and dependable cooling apparatus engineered for superior air movement within industrial machinery, electronics enclosures, and automated systems. This particular fan is designed to provide a steady airflow while keeping noise levels low and maintaining efficient energy use. Its compact square chassis, high-quality ball bearing mechanism, and compatibility with various input voltages make it an adaptable and durable choice for thermal management.

General Description

In any sealed electrical or mechanical assembly, the preservation of ideal temperatures is essential for guaranteeing performance, extending lifespan, and averting overheating or component malfunction. The 120x120x38mm AC axial fan provides a potent yet compact apparatus to achieve this. Constructed with a sturdy frame and high-precision ball bearings, it delivers reliable airflow and pressure levels across a voltage spectrum from 110V to 380V AC. Whether it is placed in control cabinets, automation equipment, HVAC setups, or computer hardware, this fan is built to supply stable cooling during continuous use.

Architecture and Materials

This fan is built with a square shape, measuring 120mm by 120mm by 38mm, which adheres to industry norms for straightforward installation and compatibility with current systems. Made from high-tensile thermoplastic or die-cast aluminum, its housing offers exceptional resilience, thermal stability, and resistance to corrosion. The impeller's blades are aerodynamically crafted to enhance air movement with minimal acoustic output.

A primary advantage of this unit is its ball bearing system, which boosts longevity and facilitates smooth running in both horizontal and vertical positions. Ball bearings are celebrated for their resistance to heat, degradation, and warping, making them perfect for strenuous applications or continuous-duty cycles.

Functional Characteristics

Across all input voltages, this fan functions at a steady velocity of 2600 revolutions per minute (RPM). It produces an impressive airflow of 81.33 cubic feet per minute (CFM), or roughly 2.27 cubic meters per minute, which ensures effective heat removal even in densely configured or high-power settings.

With a static pressure of 6.87 mmH₂O (equal to 0.69 inches H₂O), the fan has the capability to overcome airflow opposition from filters, grilles, and internal hardware. This quality makes it well-suited for cooling confined areas or systems that have moderate airflow impediments.

The acoustic level is rated at 42 dBA, providing a good compromise between powerful functionality and auditory comfort. This makes the fan appropriate for uses where noise sensitivity is a significant factor, such as in laboratory instruments, medical apparatus, or quiet office spaces.

Voltage and Power Details

To ensure compatibility with international power grids, this fan is offered in three different voltage models:

• 110V AC at 50/60 Hz

• Current: 0.22 A

• Power Usage: 24.2 W

• 220V AC at 50/60 Hz

• Current: 0.14 A

• Power Usage: 30.8 W

• 380V AC at 50/60 Hz

• Current: 0.06 A

• Power Usage: 22.8 W

All these versions retain the same RPM, airflow, and pressure ratings, permitting customers to select a model that aligns with their power source without sacrificing capability.

Mechanical Diagram and Mounting

For a secure and exact installation, the unit is equipped with eight mounting apertures of 4.3 mm diameter, spaced evenly on the frame. The center-to-center distance between holes is 105 mm, while the total frame dimension is 120 mm x 120 mm. The unit's thickness (or depth) of 38 mm allows for sufficient blade pitch and motor housing volume to generate high airflow performance.

The provided wire lead measures 300 mm in length with a tolerance of ±10 mm, offering ample reach for connecting to terminal blocks or wiring harnesses. This design simplifies integration into both new and pre-existing electrical frameworks.

Weight and Resilience

Each fan unit has a mass of about 530 grams, giving it a stable and robust structure that counters vibration during operation. The ball bearing construction further enhances its operational life, which often surpasses 50,000 hours under typical working conditions. This prolonged lifespan minimizes the frequency of maintenance or replacements, positioning the fan as a cost-effective cooling apparatus.

Applications

The 120x120x38mm AC axial fan is broadly utilized in situations where potent air circulation and enduring dependability are crucial. Frequent use cases include:

• Industrial Control Cabinets: Regulating temperature within control systems, motor drives, and PLC panels.

• Telecommunication Racks: Circulating air around servers, modems, and switches for consistent operation.

• Medical Devices: Guaranteeing the safe function of sensitive apparatus by managing internal temperature.

• Consumer Electronics: Improving the stability and longevity of devices such as amplifiers and power supplies.

• HVAC and Ventilation Systems: Assisting with air exchange and heat control in ducts and enclosures.

• 3D Printers and CNC Machines: Cooling motors, circuit boards, and enclosed hardware.

• Laboratory Equipment: Supplying airflow within microscopes, analyzers, and testing benches.

Key Benefits

• Adaptable Power Input: With models that support 110V, 220V, and 380V, the fan can be implemented across a vast array of power systems, lessening the need for voltage converters or system redesigns.

• Steady and Quiet Functioning: At 2600 RPM and 42 dBA, it provides strong airflow without generating distracting noise.

• Trustworthy Ball Bearing Mechanism: Offers a superior life expectancy, consistent output, and resistance to wear, particularly in high-temperature or continuous-use scenarios.

• High Airflow and Pressure: Pushes over 81 CFM of air and more than 6 mmH₂O of static pressure, making it suitable for cooling both open and semi-restricted enclosures.

• Compact Standard Chassis: Easy to integrate with standard openings and mounts, ensuring compatibility with existing fan guards and filtration media.

• Low Energy Use: Engineered for efficiency, with power consumption varying between 22.8 and 30.8 watts based on the voltage model.
