Description

Technical Field

[0001] This utility model relates to the field of dust removal system technology, and more specifically, to a dust removal filter for a central dust removal system. Background Technology

[0002] A central dust collection system, also known as a central vacuum system, consists of a vacuum cleaner main unit, suction pipes, suction inlets, and suction components. Anyone can perform full or partial cleaning anytime, anywhere. It is simple and convenient to operate, avoiding secondary pollution from dust and noise pollution, ensuring the cleanest indoor environment. In many real estate projects, central dust collection systems have become an essential device for improving the quality of life. Among the suction components, a particularly important dust filter is used to filter dust from the air. However, existing dust filters on the market only remove dust; because dust particles vary in size, they often clog the filter pores, requiring frequent filter replacements, causing inconvenience, wasting manpower and resources, and making collection difficult. Therefore, a dust filter for a central dust collection system is proposed to solve these problems. Utility Model Content
