Description

Technical Field

[0001] The invention relates to the technical field of air filter units, and in particular to a self-cleaning air filter unit for a clean room. Background Art

[0002] The fan filter unit is an air supply filter device with its own power device. It can be connected and used in a modular manner. It is widely used in clean rooms, clean workbenches, clean production lines and other occasions to purify the air. In order to treat the air quality in the clean room, an air filter unit is needed.

[0003] For example, the application number: 201821362585.1 proposes a fan filter unit for air detection, including a filter, a box body arranged on the filter, and a fan arranged in the box body. A vent is arranged at the bottom of the box body, and the filter includes a shell connected to the vent, a filter element arranged in the shell body, and a rigid cover wrapped on the filter element, and a plurality of air outlets arranged on the side of the shell body away from the fan; the rigid cover is detachably connected to the inside of the shell, and the filter element includes a ceramic filter layer, a KDF layer, an air purification activated carbon layer, a gold powder layer and a HEPA high-efficiency filter mesh in the direction toward the fan.
