Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically to a filtration device for HVAC engineering. Background Technology

[0002] Filtration devices in HVAC systems are used to improve indoor air quality. These devices filter pollutants such as dust, hair, and impurities from the air, making the indoor air fresher and healthier. They are usually made of fiber materials and have a large filtration area and low resistance.

[0003] The existing technology has the following problems:

[0004] The existing system does not allow for the removal and replacement of the filter plates during use. If the filter plates cannot be removed, cleaning or replacement becomes extremely difficult, potentially causing delays in maintenance and affecting the normal operation of the entire HVAC system. Over time, a large amount of dust and impurities accumulate on the filter plates. If they are not cleaned or replaced in a timely manner, the filtration efficiency will decrease, affecting air quality. Furthermore, the existing system cannot seal the outlet pipe, making it unable to effectively prevent external pollutants from entering the room. This may increase the risk of indoor air pollution, as fine particulate matter may enter the room through unsealed interfaces, posing a potential threat to the health of residents.
