DC fans are applications that move air with direct current. They draw power from a direct current source and supply an airflow like a propeller. They are very versatile in their applications and produce movement of air in virtually any atmosphere, be it air, water, or oil. In this article, we explore the application field and working principle of OD4020-05LS.

Application Field

OD4020-05LS is most commonly used in computer systems, cooling down its components in their optimized temperature. It has a high static pressure capacity due to its high static pressure fan blade shape and operates exceptionally without making too much noise. It also finds applications in the molding industry, motorized vehicles, telecommunication systems, and many other industries.

OD4020-05LS is designed to keep the environment where it is used completely dust-free. This is supported by its low static pressure fan blade shape and its high-efficiency air seals. It is also highly capable of handling VOCs (Volatile Organic Compounds) as well as solid particles. This makes it ideal for use in the food and beverage industry, chemical industry, and other air-sensitive fields.

Technical Features

• Power supply: DC 12V
• Bearing type: Long life double ball-bearing
• Power input: 2.3W
• Life-span: 70,000 hours
• Air Flow: 51.5CFM
• Noise level: 26dB(A)
• Speed: 7200RPM

Working Principle

OD4020-05LS works on the principle of direct current. The internal electric motor receives a direct current supply through a power cord. This current passes through the motor and creates a mechanism to spin fan blades. The fan blades create a suction with the air and move it across the surface area of the fan.

The current drawn from the power cord also passes through a governor that is connected to the back side of the fan and regulates the speed. When the governor is turned in the clockwise direction, the fan speed increases, whereas if it is turned counter-clockwise, the fan speed decreases. This helps in regulating the airflow according to the requirements and helps in maintaining the desired temperature level inside the system.

Conclusion

The OD4020-05LS is a highly reliable direct current fan. It is designed to keep the environment where it is operated free of dust and harmful particles. It has a wide application range and is most suitable for motorized vehicles, telecommunication systems, and the food and beverage industry. Its working principle lies in the reception of direct current and subsequent regulation of its airflow in order to maintain an optimized temperature.
