What are the functions and characteristics of a primary filter?
What are the functions and characteristics of a primary filter?For different enterprises to use the filter needs are also different, so before choosing a filter, to clarify what their needs are, if the requirements for air cleanliness are not very high, you can directly use the plate primary air filter for filtration, if the requirements of medium purification, you can use the primary filter with some medium and high-efficiency filters, and as the first stage of the air conditioning primary filter, has What are the functions and characteristics?The air conditioning primary filter is mainly used for the filtration of ≥5.0μm particles, with an efficiency of 40% to 60%, and is often used for the primary filtration of air conditioning and ventilation systems, as well as the pre-filtration of central air conditioning and centralized ventilation systems and the pre-filtration of large air compressors, with filtration levels mainly divided into G1, G2, G3, and G4. The materials used for the production of each part are also different. The outer frame is generally made of paper, aluminum, and galvanized iron, which is used to fix the filter material. It also has a good general purpose. Precautions for the use of air conditioning primary filters: Regularly check whether there is any damage to the over-plastic net of the filter, whether there is any blockage of debris on the inlet surface, and whether the surface of the filter material is broken; if the surface is blocked, it should be cleared; if the surface of the filter material is seriously damaged, it must be replaced with new filter material or reinstalled with a new filter; when installing the filter, ensure good sealing at the pressure edge with the frame to prevent air leakage, do not hit the surface of the filter with heavy objects and do not pull the surface of the filter material with force. Do not hit the surface of the filter with heavy objects or pull the surface of the filter media with force. |
