How long is the replacement cycle of the HEPA filter?

1. The primary efficiency filter should be cleaned once a week and replaced every six months. 2. The medium efficiency filter should not be cleaned, but should be replaced quarterly. 3. The high-efficiency filter should be replaced once a year. The cost factor cannot be completely referenced, and refers to the clean room, clean room, purification workshop and purification project running 24 hours a day. In addition, it has a lot to do with the operating environment of the air-conditioning fan cabinet. Keeping the sanitation of the machine room and the fresh air is the key, which is for reference only. High-efficiency filter replacement time Whether it is used in air-conditioning units or in clean rooms, dust-free workshops, purification workshops, and the end air supply of purification projects, high-efficiency filters have a certain lifespan. Which is the most reasonable time to replace it? How should this be determined? Under what circumstances is it best to replace it? Suzhou Anjing Purification is the most professional high-efficiency filter manufacturer in China. The air cleanliness monitoring adopts the "multi-point control sampling" detection method. The static method is the main method, and the dynamic method is the auxiliary method. With the most professional vision, we will evaluate the reasonable time for the replacement of the high-efficiency filter for you! 1. The resistance of the sub-high-efficiency filter has exceeded the rated initial resistance of 100Pa, or equal to 2× the initial resistance of the design or operation (3 times the low-resistance sub-high efficiency) for more than 1 year, and it can be replaced at any time when it exceeds the standard. 2. The resistance of the coarse and low-efficiency filter has exceeded the rated initial resistance of 60Pa, or equal to 2× the design or initial resistance of operation for 3-6 months, and it should be replaced at any time when it exceeds the standard. 1 wash. 3. Replace the primary and medium-efficiency filters every 6 months. The high-efficiency filter should be replaced every year. The resistance of the medium-efficiency filter has exceeded the rated initial resistance of 80Pa, or equal to 2× the design or initial resistance of operation for 6-12 months. If it exceeds the standard, replace it at any time. 4. The resistance of the high-efficiency filter has exceeded the rated initial resistance of 160Pa, or is equal to 2× the design or initial resistance of operation for more than 3 years, and it can be replaced at any time when it exceeds the standard. The installation of the high-efficiency air filter in the operating room should meet the following requirements: 1) The high-efficiency air filter in the operating room should be installed immediately after passing the visual inspection; 2) The frame for installing the high-efficiency filter should be flat and clean, and each high-efficiency air filter should be installed. The flatness deviation of the installation frame of the filter and the filter without partition shall not exceed 1~2mm; 3) The installation direction of the air filter must be correct, and the surrounding and interface of the filter should be tight and leak-proof after installation; 4) The high-efficiency filter When using a mechanical seal, it should be sealed with an airtight gasket; after installation, the compression of the gasket should be uniform, and scanning for leaks should be performed after installation.
