Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of FFU fans, in particular to a FFU fan structure for purification. Background Art
[0002] Air purification equipment refers to products that can filter out or kill air pollutants and effectively improve air cleanliness. It mainly focuses on household and commercial air purification equipment that removes indoor air pollution. Air purification equipment can filter out pollutants such as airborne particulates, bacteria, viruses, fungal spores, pollen, asbestos and radon decay products;
[0003] FFU, or fan filter unit, is an air purification device that combines a fan and a high-efficiency filter. The FFU fan draws in air through the operation of the fan, and then filters the air through the high-efficiency filter. The filtered clean air is sent out from the air outlet at a uniform speed under a certain static pressure, forming a clean air laminar flow in the clean room, thereby ensuring that the air cleanliness level in the clean room meets the requirements of production or experiments;
[0004] Currently, in the existing technology, FFU fans are usually installed above the ceiling of the clean room or in the static pressure box. This high installation position makes daily inspection and cleaning more difficult. If the fan is not cleaned conveniently, dust and dirt accumulated over a long period of time will stick to the fan blades, increasing the resistance inside the fan. This will cause the air flow through the fan to decrease, slowing the air circulation speed in the clean room and failing to remove pollutants in a timely and effective manner.
[0005] In order to solve the above problems, this application proposes a FFU fan structure for purification. Utility Model Content
