Key Features and Advantages:

Main Features:

1.  AC Brushless Design: As an AC brushless fan, it generally offers longer lifespan, lower maintenance requirements, and less electromagnetic interference during operation compared to brushed fans.

2.  Large Size and High Power: With dimensions of Φ280x80mm, it falls into the category of large industrial fans. Its rated input power ranges from 112-158 watts, indicating strong air handling capabilities.

3.  Ball Bearing: The use of ball bearings typically provides a longer service life, better reliability, and support for various mounting orientations, being less affected by gravity.

4.  All-Aluminum Construction: Both the frame and impeller are made of aluminum alloy. Aluminum offers good heat dissipation, high strength, corrosion resistance, and is relatively lightweight (rated single weight 2800g). It also meets the UL94V-0 flammability rating, ensuring high safety.

5.  High Air Flow and High Air Pressure:

a)   Maximum air flow can reach 30.8-31.9 m3/min (1090-1130 CFM).

b)   Maximum air pressure can reach 19.8/16.5 mmH2​O (0.78/0.65 Inch H2​O).

c)   These parameters indicate that the fan can effectively operate in environments requiring large air volume or needing to overcome higher system resistance (e.g., passing through filters or dense components).

6.  Wide Voltage Compatibility: Available in both 110VAC and 220VAC models (MG28080H110X and MG28080H220X), both supporting 50/60Hz frequencies. This makes the product highly adaptable to different power standards across various regions globally.

7.  Standard Mounting Dimensions: Detailed dimension drawings, including 280x280mm outer dimensions and mounting hole pitch, facilitate mechanical design and integration for users.

Main Advantages:

1.  Long Lifespan and High Reliability: The brushless motor combined with ball bearings significantly extends the fan’s overall service life and reduces failure rates, leading to lower maintenance costs.

2.  Excellent Cooling Performance: Its high air flow and air pressure characteristics make it an excellent choice for industrial equipment, data centers, HVAC systems, and other scenarios requiring powerful cooling or air circulation. The aluminum construction also aids in the fan’s own heat dissipation.

3.  Robust and Durable: The all-aluminum construction not only enhances the product’s durability and impact resistance but also allows it to operate stably in relatively harsh industrial environments. The UL94V-0 flammability rating further boosts safety.

4.  Global Applicability: Support for both 110V and 220V voltages, along with 50/60Hz frequencies, enables it to meet diverse power standard requirements in international markets, facilitating export and global deployment.

5.  Easy Integration: Detailed dimension drawings and standardized mounting hole positions simplify product selection and mechanical design for engineers, accelerating client product development cycles.

6.  High Efficiency (Implied): Although not directly specified, AC brushless fans generally offer higher energy efficiency compared to brushed motors, contributing to energy savings.
