Application Scenarios And Filtration Range Of Air Filters

1. Coarse efficiency filters are mainly used as pre filters at the fresh air inlet of air conditioning systems to trap large particles in the atmosphere. The filtering objects are suspended particles larger than 5 μ m and settling particles larger than 10 μ m, as well as various foreign objects, to prevent them from entering the system. The filter materials are generally spray bonded cotton, polyester non-woven fabric, and polypropylene fiber. The filtration efficiency is based on filtering particles ≥ 5 μ m.
2. Medium efficiency air filter
Due to the pre filter in front of it intercepting large particles, it can also serve as a final filter for general air conditioning systems and a pre filter for high-efficiency filters in purification air conditioning systems. The filter materials are generally polyester non-woven fabric, polypropylene fiber, and glass fiber. Mainly used for intercepting suspended particles of 1-10 μ m, with efficiency based on filtering particles ≥ 1 μ m.
3. High and medium efficiency filters can be used as end filters for systems with general purification levels, or as intermediate filters for high-efficiency filters; The filter materials are generally polyester non-woven fabric, polypropylene fiber, and glass fiber. Mainly used for intercepting 1-5 μ m particles, with efficiency based on filtering particles ≥ 1 μ m.
4. Sub high efficiency filters are mainly used as clean room end filters, as well as pre filters for high-efficiency filters and final filters for fresh air systems, to improve the quality of fresh air. The filter material is generally made of polypropylene fiber or glass fiber. Mainly used for intercepting particles below 1 μ m, with efficiency based on filtering particles ≥ 0.5 μ m.
5. The high-efficiency filter (chao high-efficiency filter) is mainly the end filter of the clean room to ensure the achievement of cleanliness levels at all levels. Its efficiency is based on filtering particles ≥ 0.5 μ m. The filter material is generally ultrafine glass fiber.
