DC Centrifugal Fan

一、Product Overview

DC centrifugal fan refers to a centrifugal fan driven by a DC power supply. It integrates multiple advantages, including easy installation, high efficiency, low power consumption, low noise, long service life and smooth operation, etc. In addition, this type of fan also features stepless speed regulation, soft start and reduction of mechanical vibration, enabling it to demonstrate outstanding performance in numerous industries. Although its production process is more complex and the cost is relatively higher compared with AC centrifugal fans, its unique performance advantages make it the main choice for many high-end ventilation and heat dissipation applications.

二、Structural composition

The main components of a DC centrifugal fan include the impeller, casing, air inlet, cooling fan blades, connectors, transmission parts and brackets, etc. Among them, the backward impeller is driven by an outer rotor DC brushless motor, and the motor is equipped with ball bearings with grease inside to ensure long-term stable operation. The impeller is injection molded with a certain amount of plastic material and has an internal steel ring for installing the outer rotor brushless motor. The air inlet is designed as a convergent streamlined shape, effectively reducing airflow loss and enhancing the overall working efficiency of the fan.

三、Characteristics and advantages

1. Superior speed regulation performance: The speed regulation control of DC centrifugal fans is simple and flexible, and its speed regulation performance is superior to that of traditional similar products.
2. High-efficiency operation: By eliminating current loss, the operating efficiency of the fan has been significantly enhanced, far exceeding that of similar products.
3. High power factor: Compared with similar products, the power factor of the fan is higher, which helps to save energy.
4. Simple structure and convenient maintenance: This type of fan has a simple design, which is convenient for daily maintenance. It also has multiple advantages such as high cost performance, high air pressure, low operating noise and high working efficiency.

四、Industry application

Due to their high efficiency and multi-functionality, DC centrifugal fans are widely used in various industries, such as air conditioning and refrigeration, fresh air systems, household appliances, air purification systems, automobiles and office equipment, duct ventilation, explosion-proof equipment for mines, dust-free workshops, construction machinery, medical equipment, and education and training. It can provide reliable ventilation and cooling solutions in both household and industrial environments.
