Precautions for replacing air filters at all levels in the purification system
Precautions for replacing air filters at all levels in the purification systemThe entire purification system used in the purification of air filter types are many, there is primary, medium, and high efficiency, etc., these are essential, and in addition to how to use them correctly, we want to see with you today to replace the filter equipment considerations!I. Familiarity with the replacement cycle of various types of air filters, under what circumstances should be replaced need to be based on the specific use of individual equipment and conditions. 1. fresh air filter, also known as pre-filter or primary filter; the intermediate filter can also be called the intermediate air filter, both of which can be replaced when the final resistance is two times the value of the initial resistance; 2. End air filters, that is, high efficiency, ultra-high efficiency air filter replacement cycle should be properly extended, according to the actual situation to decide. II. Notes for removing air filters 1. Before dismantling the clean room equipment and floor should be wrapped and covered with plastic film to prevent the dust accumulated in the air ducts and static pressure boxes from falling during the dismantling process and causing pollution to the equipment and floor; 2. After dismantling the air filter, the installation frame, supply, and return air ducts should be thoroughly cleaned; 3. When dismantling, it is recommended to follow the order of primary, medium, sub-high, high, and ultra-high efficiency air filters to effectively reduce the amount of dust entering the clean room; 4. Because the replacement cycle of the whole system is generally long, all equipment in the system can be thoroughly cleaned at the same time as the air filter is replaced. III. Cleaning fine dust particles After the removal of the air filter in the whole system, we can start the fan in the system for the air supply duct, installation frame, etc. for timely cleaning to remove the fine dust particles adhering to the surface. IV. Performance testing after replacement After the replacement of all filter equipment in the system, the system fan should be started in time to put all the equipment into operation and to carry out a comprehensive performance test of the equipment, which can only be put into use after passing the test. V. Afterwards, to ensure that the pollution particles in the clean area are controlled within the required number of clean levels, various levels of air filter equipment are generally used in the purified air conditioning system to intercept the dust particles entering the clean room airflow. |
