The product is a DC brushless fan 172mm x 150mm x 25mm  type, manufactured by Guangzhou Mega Technology Co., Ltd. It is a DC brushless fan, also known as a axial fan. Axial fans are a type of fan that uses a motor to rotate a hub, which in turn rotates a set of blades. This rotation creates airflow that is directed along the axis of the fan.

Key Features

1. Brushless DC motor: This type of motor offers several advantages over traditional brushed motors, including:
   • Quiet operation: Brushless motors do not produce the noise and vibration associated with brushed motors due to the absence of brushes.
   • Long life: Brushless motors have no brushes to wear out, so they typically last much longer than brushed motors.
   • High efficiency: Brushless motors are more efficient than brushed motors, which means they generate less heat and consume less power.
2. UL94V-0 flame retardant plastic housing: This type of plastic is highly resistant to fire and will not easily burn. This is an important safety feature for any fan that is used in an environment where there is a risk of fire.
3. Two ball bearings: Ball bearings are a type of bearing that is known for their low friction and long life. They are also very quiet, which makes them a good choice for fans.
4. Wide operating voltage range: The fan can operate on a wide range of voltages, from 7.5V to 13.5V for the 12V model. This makes it versatile and can be used in a variety of applications.
5. High airflow and static pressure: The fan has a maximum airflow of 246.03 CFM and a maximum static pressure of 18.34 mmH2O. This means that it can move a large amount of air and overcome significant resistance.

Advantages

1. Quiet operation: The brushless motor and ball bearings make the fan very quiet, making it a good choice for use in homes, offices, and other noise-sensitive environments.
2. Long life: The brushless motor and ball bearings also make the fan very durable, so it is likely to last for many years.
3. High efficiency: The brushless motor is very efficient, which means that it will save you money on your energy bills.
4. Wide operating voltage range: The fan can be used with a variety of power sources, making it versatile and easy to install.
5. High airflow and static pressure: The fan can move a large amount of air and overcome significant resistance, making it suitable for a variety of applications.
