120x120x38mm AC Axial Fan – High-Efficiency Ball Bearing Fan for Applications
The 120x120x38mm AC axial fan is a robust and reliable cooling solution designed for high-performance air circulation in industrial equipment, electronic enclosures, and automation systems. This AC axial fan is engineered to deliver consistent airflow while maintaining low noise levels and efficient power consumption. Its compact square frame, premium ball bearing system, and compatibility with multiple input voltages make it a versatile and long-lasting thermal management option.
Overview
In any enclosed electrical or mechanical system, maintaining optimal temperature is critical to ensure performance, prolong lifespan, and prevent overheating or component failure. The 120x120x38mm AC axial fan offers a powerful yet compact solution. Built with a durable frame and high-precision ball bearing, it provides dependable airflow and pressure ratings across a range of voltages from 110V to 380V AC. Whether installed in control cabinets, automation machinery, HVAC systems, or computing equipment, this AC axial fan is designed to deliver stable cooling under continuous operation.
Design and Construction
The AC axial fan features a square form factor with dimensions of 120mm x 120mm x 38mm, conforming to industry standards for easy mounting and compatibility with existing systems. Constructed from high-strength thermoplastic or die-cast aluminum, the housing provides excellent durability, thermal stability, and corrosion resistance. The impeller blades are aerodynamically designed to optimize airflow with minimal noise generation.
A key strength of this fan lies in its ball bearing system, which enhances longevity and enables smooth operation in both horizontal and vertical orientations. Ball bearings are known for their resistance to heat, wear, and deformation—making them ideal for demanding applications or continuous-duty operations.
Performance Characteristics
The AC axial fan operates at a constant speed of 2600 revolutions per minute (RPM) across all input voltages. It delivers an impressive airflow of 81.33 cubic feet per minute (CFM) or approximately 2.27 cubic meters per minute, ensuring effective heat dissipation even in densely packed or high-power environments.
With a static pressure of 6.87 mmH₂O (equivalent to 0.69 inches H₂O), the AC axial fan is capable of overcoming airflow resistance from filters, grilles, and internal components. This makes it ideal for cooling confined spaces or systems with moderate airflow obstructions.
The noise level is rated at 42 dBA, offering a balance between powerful performance and acoustic comfort. This makes the AC axial fan suitable for applications where noise sensitivity is a concern, such as in laboratory equipment, medical devices, or quiet workspaces.
Voltage and Power Specifications
The AC axial fan is available in three voltage variants, ensuring compatibility with global power standards:
- 110V AC at 50/60 Hz
- Current: 0.22 A
- Power Consumption: 24.2 W
- 220V AC at 50/60 Hz
- Current: 0.14 A
- Power Consumption: 30.8 W
- 380V AC at 50/60 Hz
- Current: 0.06 A
- Power Consumption: 22.8 W
All versions maintain the same RPM, airflow, and pressure specifications, allowing users to choose a model that best matches their voltage supply without compromising performance.
Mechanical Drawing and Installation
The AC axial fan comes with eight mounting holes of 4.3 mm diameter spaced evenly across the frame for secure and precise installation. The hole-to-hole center spacing is 105 mm, while the overall frame size is 120 mm x 120 mm. The thickness (or depth) of 38 mm provides adequate blade pitch and motor housing space to achieve high airflow performance.
The included wire lead is 300 mm long with a ±10 mm tolerance, providing ample length for connection to terminal blocks or wiring harnesses. This design facilitates simple integration into new and existing electrical systems.
Weight and Durability
Each AC axial fan unit weighs approximately 530 grams, providing a stable and solid form factor that resists vibration during operation. The ball bearing design further improves its operational lifespan, often exceeding 50,000 hours under normal operating conditions. This extended life reduces the need for frequent maintenance or replacement, making the AC axial fan a cost-effective cooling solution.
