An Overview of the 6-Inch AC Axial Fan (110V-380V, Ball/Sleeve Bearing Options)

The 6-inch AC axial fan represents an essential and adaptable element, created to deliver highly efficient air circulation in a compact and resilient package. Engineered for optimal reliability and performance, this fan is designed to satisfy the cooling requirements of diverse industrial, commercial, and electronic equipment settings.

With its compatibility across a wide voltage spectrum (110V, 220V, 380V) and frequency support for both 50Hz and 60Hz electrical grids, it provides unparalleled adaptability for worldwide implementation. Available with a choice of ball or sleeve bearing mechanisms, it guarantees a long service life and peak cooling performance under various operational demands.

Robust Construction and Functional Architecture

This fan is built with a resilient metal frame and precisely engineered impeller blades, which ensure stable rotation and minimal vibration. The black-finished housing is not only resistant to corrosion but also crafted to uphold its performance in demanding conditions. Possessing a diameter of 172mm and a thickness of 51.5mm, its compact form factor enables it to fit within standard 6-inch fan enclosures, ensuring wide compatibility with many cooling systems.

The design incorporates pre-drilled mounting apertures for swift and secure installation, while its optimized airflow channel ensures air is effectively moved through the system. Its aerodynamic blade structure powerfully drives air with minimal drag, guaranteeing high airflow without undue power consumption or noise.

Flexibility in Voltage and Frequency

One of this fan's most notable characteristics is its support for three distinct rated voltages:

• 110V AC

• 220V AC

• 380V AC

Every voltage variant operates smoothly at both 50Hz and 60Hz, establishing this fan as a universally compatible cooling solution. This feature permits manufacturers and engineers to integrate it into systems across different countries and regions without needing voltage converters or alternative fan models.

Superior Airflow Capabilities

Depending on the specific voltage and bearing configuration, this unit produces a remarkable airflow rate between 180 and 210 CFM (cubic feet per minute). This translates to approximately 5.1 to 5.9 m³/min, offering exceptional ventilation capacity suitable for:

• Server enclosures

• Power supply units

• Inverters

• Industrial equipment

• Control panels

• HVAC systems

With a rated rotational speed between 2500 RPM and 2950 RPM, it strikes a balance between high performance and energy efficiency. Its consistent airflow keeps components within safe operating temperature limits, thereby extending their lifespan and mitigating the risk of failures related to overheating.

Bearing Choices: Ball Versus Sleeve

To accommodate different durability and budget needs, the fan is offered with both ball bearing and sleeve bearing systems.

• Ball Bearings: Offer an extended operational life and perform better in high-temperature and high-load scenarios. They are commonly used in mission-critical or continuous-duty equipment.

• Sleeve Bearings: Represent a more economical choice and are quieter at lower speeds. They are well-suited for applications involving intermittent or light-duty use.

Both options are engineered from high-quality materials, providing smooth, low-friction operation with reduced wear over their service life.

Energy Consumption and Efficiency

Despite its powerful output, the fan maintains a low power consumption profile. The input wattage for each model is as follows:

• 110V models: 42/43W

• 220V models: 36/34W

• 380V models: 34/33W

This level of energy efficiency makes it a cost-effective cooling solution over the long term, helping to minimize operational expenses and environmental footprint. Its rated current spans from 0.63A at 110V down to 0.13A at 380V, providing scalable performance with an optimized power draw.

Static Pressure and Acoustic Management

This fan is designed to sustain strong airflow even within systems that have backpressure or obstructions. It achieves a static pressure between 11.1 and 11.5 mmH₂O (millimeters of water), or 0.43 to 0.44 InchH₂O. This capability allows the fan to deliver consistent ventilation through filters, vents, or ducting, ensuring that even tightly packed or enclosed components receive sufficient cooling.

Furthermore, the fan operates with noise levels as low as 51 dBA and up to 56 dBA, depending on the bearing and speed. This makes it appropriate for deployment in noise-sensitive settings like laboratories, data centers, and enclosed control rooms. Ball-bearing versions tend to produce slightly more noise due to higher speeds, whereas sleeve-bearing fans are somewhat quieter under typical loads.

Wiring and Electrical Details

Each fan is equipped with 18 AWG wires and a lead length of approximately 280 mm ± 20 mm, which allows for convenient wiring and integration into existing power setups. A Terminal Type 7.5 with a 0.5mm thickness ensures dependable electrical connections.

Physical Specifications and Installation

The fan's external measurements are:

• Frame Diameter: 172 mm

• Mounting Hole Distance: 150 mm ± 0.5 mm

• Frame Depth: 51.5 mm ± 0.5 mm

• Mounting Hole Diameter: 4.3 mm ± 0.2 mm

These dimensions make the fan compliant with most 6-inch standard mount sizes used in industrial, commercial, and electronics cooling enclosures. The design also supports both vertical and horizontal mounting orientations.

Weight and Handling

Every unit weighs approximately 920 grams, which provides a stable structure that resists vibration and enhances cooling consistency. The weight is balanced to prevent stress on mounting surfaces while maintaining sturdiness in high-vibration installations, such as factory machinery or mobile equipment.

Range of Applications

The 6-inch AC axial fan is well-suited for a broad array of applications across numerous industries, including:

• Industrial Automation: Cooling electrical cabinets, PLCs, and controllers.

• Telecommunications: Providing ventilation in network racks and servers.

• Power Electronics: Used within inverters, rectifiers, and UPS systems.

• Medical Equipment: Ensuring stable temperatures in sensitive diagnostic tools.

• HVAC Systems: Integrated into air purifiers, exhaust units, and fan coils.

• Commercial Appliances: Cooling components in vending machines, display freezers, and industrial ovens.

In Conclusion

Whether you are designing a new product or upgrading a legacy system, the 6-Inch AC axial fan is a dependable and effective cooling solution. With its wide voltage range, choice of bearings, excellent airflow, and low noise output, it integrates perfectly into many environments. Engineered for industrial durability and global compatibility, this fan stands as the premier choice for engineers, technicians, and manufacturers seeking quality, performance, and value.

Let this high-performance axial fan help you maintain optimal operating conditions, reduce system downtime, and extend the life of your valuable equipment.
