  • How often should Air Shower’s filter cotton be replaced?

    How often should Air Shower’s filter cotton be replaced?
    The Pre-filters and HEPA filters are mainly using in the Air Shower. The efficiency of the pre-filters is between (G1-G4) in generally. According to the data analysis of the air shower users, for general users, the pre-filter should be maintained once in about 6 months based on 8 hours of work per day. To be noticed that the pre-filter is washable, but should not be washed exceed 3 times, means the longest life span is generally 2 years, and it has to be replaced.     The air shower is generally equipped with H13 (99.99%) HEPA filter. It usually needs to be replaced every 1-2 years, according to the management of ordinary clean rooms. But the HEPA filter in the air shower is different. If it using in the same condition as the first item above, the HEPA filter in the air shower can generally be used for 2 years or even longer. The premise is the normal maintenance, including frequent cleaning of the air shower, no dust etc. if you want the HEPA be used for a longer time. The above is about: "How often is the filter cotton in the air shower room replaced?" I hope everyone can understand, please feel free to contact us if you having any questions!
  • How to measure air volume at HEPA BOX

    How to measure air volume at HEPA BOX
    High-efficiency air outlets are ideal terminal filtration devices and are widely used in the pharmaceutical, health, electronics, chemical and other industries. In order to verify whether the clean room can meet the cleanliness requirements, it is necessary to test the clean room and high-efficiency air outlets, so its detection is very important.    How to measure the air volume of high-efficiency air outlets:    1. You can use the air volume hood to directly aim at the nozzle for one-time measurement. Since your nozzle has many small holes (to make the air volume uniform) and there is a grille, then your anemometer can be kept 3-5 cm away from the nozzle. If you have a thermal anemometer, try to face the gap instead of the grille, and measure the average value by the grid method. The same cross-section can be measured.   2. You can measure at multiple points at a distance of 2 times the width of the diffuser from the air outlet. The measuring points should be like a grid and then the wind speed is averaged. The sizes of these vents are similar. Use tinplate or even plastic plate to make a barrel that is slightly larger than the cross-section of the air outlet, and then cover the barrel on the air outlet when measuring, and then use the anemometer to measure the nozzle of the barrel at multiple points and calculate the average value. 3. Clean air can be obtained through the clean air conditioning circulation fan, high-efficiency air filter, medium-efficiency filter, and primary air filter. The cleanliness is different, and the wind flow direction is different. Of course, it is also necessary to supplement some fresh air through the fresh air outlet, otherwise people will feel stuffy inside.      Air volume measurement of high-efficiency air outlet:    1. The detection method of high-efficiency air outlet uses active sampling and passive sampling. Active sampling uses filtering method and impact method. The filtering method allows a certain amount of air to pass through an analytical filter.   2. The impact method can use Anderson sampler, Lute centrifugal sampler, and slit sampler. Passive sampling uses the landing method. The principle of diffusion of open agar plates with suspended particles is used.   3. Of course, with the development of science and technology today, some more sophisticated detection instruments can also be used to quickly detect it.

  • KLC Share | Solution to high humidity in dust-free workshop
    Nov 08, 2024
    KLC Share | Solution to high humidity in dust-free workshop
    In the use of dust-free workshop, in addition to understanding the management system of dust-free workshop, we must also know how to control the humidity of dust-free workshop. The temperature and humidity of dust-free workshop are mainly determined according to process requirements, but under the condition of meeting process requirements, people's comfort should be considered. Therefore, we need to take effective solutions to the situation of high humidity in dust-free workshop.    How to reduce the high humidity in the dust-free workshop:  High humidity actually reduces the accumulation of static charge on the surface of the dust-free workshop and clean room. Lower humidity is more suitable for the accumulation of charge and becomes a potentially destructive source of static discharge. When the relative humidity exceeds 50%, the static charge begins to dissipate rapidly, but when the relative humidity is less than 30%, it can persist for a long time on an insulator or ungrounded surface. Therefore, in an environment with high relative humidity, the capillary force of concentrated water forms a connection bond between the particles and the surface, which can increase the adhesion of the particles to the siliceous surface. It is not important when the relative humidity is less than 50%, but when the relative humidity is around 70%, it becomes the main force for adhesion between particles.      Solutions to high humidity in dust-free workshops:  1. Increase dehumidification and drying: Add a dehumidifier in the clean workshop to increase the dryness of the workshop, and add it in the air conditioning duct during installation. 2. Seal equipment: Seal the equipment that may be affected as much as possible to reduce the impact of the humid environment in the workshop to achieve the purpose of safe storage. 3. Maintain ventilation: Ventilation can form convection of air inside and outside the workshop. When the temperature difference between inside and outside the workshop is greater, the air will flow faster, and the dehumidification effect on the workshop will naturally be more significant. 4. Moisture absorption in the workshop: In the rainy season or rainy days, when the humidity in the workshop is too high and it is not suitable for product storage, and the humidity outside the workshop is too high, it is not suitable for ventilation and moisture dissipation. You can use moisture absorption in the sealed warehouse to reduce the humidity in the warehouse.     In view of the problem of excessive humidity in the dust-free workshop, the use of a comprehensive solution can effectively improve the control ability of the workshop environment. Strengthening ventilation, using dehumidification equipment, controlling temperature, managing materials and strengthening monitoring are all important measures to ensure the stability of humidity in the dust-free workshop. Through these methods, the smooth progress of the production process can be ensured and the quality and safety of the products can be maintained.
