W-type high-efficiency filter, also known as high air volume W-type combined filter, the frame of the combined high-efficiency filter is divided into plastic frame, galvanized frame, aluminum frame, stainless steel frame, and commonly used plastic frame combined high-efficiency filters. Suitable for use in research and production departments with various process

The high-efficiency filter without partition is widely used in purification systems. The product filter uses ultra-fine glass fiber filter paper, and hot melt adhesive is used as a separator between the filter papers to increase the filtration area and improve the strength of the product. Diamond shaped metal protective mesh is used on the inlet and outlet surfaces of the filter, which can effectively protect the filter element from damage. Polyurethane adhesive is used to seal the filter element and the outer frame, ensuring the sealing effect of the product. It is widely used in precision electronics, biopharmaceuticals, semiconductors, food and other fields.

The high-efficiency filter with partition belongs to the end filtration in the purification system. It is mainly installed at the top of the clean room for air supply, used to filter particles, dust and suspended solids within 0.3-0.5um. The filter uses wavy partition paper in the middle to separate the filter media, improving the dust holding capacity and air volume of the product. The filter paper and the outer frame are sealed with polyurethane glue to ensure the airtightness of the product. Therefore, this product model of filter is widely used in environments with variable air volume and abnormal pressure.

Medium efficiency filters belong to intermediate filtration in purification systems, mainly used for intermediate filtration in central air conditioning systems of clean rooms. They are used to filter particles, dust, and suspended solids within 1-5um. They are generally installed in the middle of primary and high-efficiency filters to improve the working environment of high-efficiency filters. They are made of non-woven fabric materials with F5-F9 filtration efficiency, and have the characteristics of high air volume, low resistance, high dust capacity, and washable and reusable.
