OD8020-12MB

DC Fans are a type of fan commonly used in industrial, commercial and residential applications. It is a fan powered by direct current (DC) power. DC Fans are characterized by their low power consumption, low noise level, and long lifetime. They are available in a variety of sizes, voltages, speed and airflow settings. OD8020-12MB is one of the most popular DC fans.

Overview

OD8020-12MB is a high efficiency DC fan which has a high performance capability. It is a framed type fan with a built-in double ball bearing motor for long lifetime and a water-proof sealant for effective protection against dust and other environmental contaminants. It has an external rotor type motor, making it easier to maintain and install in confined spaces. The fan’s airflow rating is high (8020 m3/hr) and the static pressure rating also very good (up to 12 units). The fan comes with a choice of seven different speeds, ranging from 40 to 3000 RPM.

Features and Benefits

The OD8020-12MB DC fan has a number of features and benefits that make it ideal for a variety of applications. It is designed for high efficiency operation (measured at airflow/power), and offers high reliability through the use of double ball bearing motor and a waterproof seal. In addition, its external rotor type motor is extremely efficient and provides lower noise and vibration levels. It can be operated over a wide temperature range (-25ºC to +85ºC), and supports various mounting directions. As with all DC fans, the OD8020-12MB features a low noise level (<25 dB(A)) and a long lifetime (over 80,000 hours).

Applications

The OD8020-12MB DC fan is a highly reliable and efficient fan that is suitable for a variety of applications, including cooling and ventilation for computers, industrial machinery and other electrical equipment, air conditioning systems, commercial refrigeration and other cooling needs, environmental control systems, and a variety of cooling needs in residential and commercial buildings. It can also be used in automobiles and other types of vehicles.

Working Principle

The OD8020-12MB DC fan operates on the principle of air passing over a spinning fan blade. The fan blade is powered by a direct current (DC) motor. The motor has a set of two ball bearings which allows the fan blades to spin smoothly and quietly. As the fan blade spins, air is drawn over the blade and circulated around the fan housing. This creates a vacuum, which in turn forces air to be drawn in to the fan housing and pushed out the other side.

The air passing over the fan blade is directed in a circular motion around the fan housing. This produces a vortex and causes the air to travel faster in a swirling motion. This faster motion helps to increase the airflow passing over the fan blade, and thus increases the cooling capacity of the fan. In addition, the high speed of the fan blades adds to the noise level of the fan.

Conclusion

The OD8020-12MB DC fan is an efficient and reliable fan that is highly suitable for a variety of applications, from cooling computers and other electrical equipment to cooling commercial and residential buildings. It features a high airflow rating, a long lifetime, and a low noise level, making it an ideal choice for many different applications. The fan operates on the principle of air being drawn over the fan blade, which is powered by a DC motor. The fan produces a vortex which increases the airflow and cooling capacity, while at the same time adds to the noise level.
