Maintenance frequency of air outlets
Maintenance frequency of air outlets1. The replacement frequency of high-efficiency filters varies according to different types and usage conditions.The replacement frequency of high-efficiency filters varies according to different types and usage conditions. Generally speaking, in ordinary environments, the replacement cycle of high-efficiency filters is usually 3 to 6 months; for more polluted areas in industrial environments, such as manufacturing plants and chemical plants, the replacement time of high-efficiency filters can be shortened to 1 to 3 months; in places with extremely high air quality requirements such as medical facilities, laboratories and clean rooms, it is recommended to check the filters monthly and replace them in time when resistance increases or efficiency decreases; high-temperature filters are usually recommended to be replaced every 6 months to 1 year. 2. It is recommended that the frequency of daily inspection of vents is once a week, and quarterly inspection is once every 3 months. Daily inspection of the internal and external conditions of the vents, including connectors, seals, filters, and other parts, to check for damage, shedding, or hole blockage, the frequency is once a week. During the quarterly inspection, the inspection items are more comprehensive, including the stability, ventilation effect, safety, and other aspects of the vents, ensuring that the vents can be stably installed in the equipment position, and the resistance card density should meet the specified acceptance standards; the notches, apertures and angles of the vents should meet the design specifications, and the ventilation performance should meet the specified acceptance standards; the vents should have safety protection measures such as fire prevention, explosion prevention, and waterproofing to deal with emergencies and emergency plans when disasters occur. 3. The vents should be cleaned after being used for more than one year. After the vents have been used for more than one year, they should be cleaned to thoroughly remove internal deposits, foreign matter attachments, etc. to ensure that the vents work properly. Before cleaning, the ventilation system should be stopped and the vents should be closed. When cleaning, a high-pressure water gun or a hand-held water sprayer can be used to clean the filter screen, machinery, seals, etc. inside the vents to remove deposits and dirt; use a soft towel, sponge, or cloth to wipe the various parts of the outside of the vents to ensure that there is no residue and dirt. After cleaning, maintenance and care should also be carried out. According to the inspection and cleaning conditions, damaged and obsolete parts should be replaced in time to ensure the normal use and long-term stable operation of the vent. |
