In today’s world, the need for clean and healthy air is more pressing than ever. Whether in industrial settings, commercial spaces, or homes, air quality plays a significant role in overall health and well-being. Among the most common systems used to maintain clean air are fan and filter systems. These systems combine two essential components： the fan, which circulates air, and the filter, which cleans the air. Together, they play an integral role in various applications, from air purifiers to industrial ventilation systems.
The Function of the Fan
The fan is a mechanical device that generates airflow. Its primary purpose is to move air from one place to another, either to ventilate a space or to improve air circulation. In a fan and filter system, the fan draws in the surrounding air, pushing it through ducts or other passageways. It is the starting point for the air purification process, ensuring that air flows through the system with sufficient force and volume. The fan’s effectiveness is measured by several factors, including airflow capacity (often denoted in cubic feet per minute, CFM), energy efficiency, and noise level. Different fans are suited to various environments. For example, industrial fans may need to move large volumes of air to clear dust or fumes, while smaller fans used in home air purifiers focus on quieter, more controlled airflow.
