What are high-efficiency air outlets and integrated air outlets?
What are high-efficiency air outlets and integrated air outlets?Answer: The shell of the high-efficiency air outlet is made of a high-quality cold-rolled steel plate, the surface is electrostatically sprayed, and it contains a static pressure box high-efficiency filter, and a diffuser. In the reconstruction and construction of individual clean rooms, it can be used as a terminal high-efficiency filtration device in clean sheds, etc., with the advantages of low investment and simple construction.The integrated air outlet filter is a closed structure, low profile, lightweight shell, with a high-efficiency filter installed in the middle. It has filtering performance and is connected to the air duct. The filter group is used in clean rooms with laminar and non-laminar grades of 100,000 to 10. The closed design prevents internal gaps and side leakage and meets the strict requirements of clean rooms for air quality. Its low profile, lightweight, and disposable design make it suitable for hospital operating rooms, laboratories, pharmaceuticals, microelectronics, films, and food processing factories. What is the current glue adjustment ratio and standard dosage of high-efficiency filters with partitions and high-efficiency filters without partitions? Answer: The sealants currently used for filters with or without partitions are A and B glue, while other manufacturers use polyurethane glue. The ratio of A and B glue is 1:2, and its sealing performance is relatively good, but once the ratio is out of balance, it will cause serious consequences, such as the glue not drying, or there are bubbles in the glue, causing the filter to be scrapped. What are the standard dimensions and acceptable deviations of the diagonals of primary, medium, sub-high efficiency, and high-efficiency filters? Answer: The standard diagonal of primary, medium, and high-efficiency filters is the sum of the squares of the two right angles, and then the square root: find the standard size of the oblique line, that is, the standard diagonal. The acceptable deviation of general filters is: for filters greater than 700mm, the allowable deviation of the diagonal is less than or equal to 4.5mm, and for filters less than or equal to 700mm, the allowable deviation of the diagonal is less than or equal to 2.3mm. What is resistance, initial resistance, and final resistance? Answer: Resistance: Fibers make the airflow detour and produce small resistance. The sum of the resistances of countless fibers is the resistance of the filter. Initial resistance: the air resistance of the undusted test filter when it passes the rated air volume. Final resistance: refers to the initial resistance rising to the specified value due to dust accumulation on the filter under rated air volume, which is generally twice the initial resistance, and can also be recommended by the manufacturer, and the unit is expressed in Pa. Atmospheric dust, artificial dust, and the proportion of artificial dust? Answer: Atmospheric dust refers to the suspended particles contained in the natural air outdoors or indoors that are connected to the outdoors, while artificial dust is mainly composed of road dust, carbon black, and short fluff, and its composition ratio is: 72%, 25%, 3%, etc. What are the test filters and terminal filters? Answer: The filter that is tested according to the standard is called the test filter. The terminal filter refers to the filter used to capture the artificial dust of the test filter. What is the rated air volume? What is the dust holding capacity? Answer: The air volume designed to be handled by the filter per the unit time specified by the manufacturer is expressed in m3/h, and the dust holding capacity refers to the product of the total mass of artificial dust applied when the test filter reaches the final resistance and the average weight efficiency of the test filter, expressed in "g". What is the standard folding number of high-efficiency filters with partitions, and the factors that affect and determine its folding number? Answer: The standard folding number of high-efficiency filters with partitions is determined by two important factors, such as the height of the partition paper and the tightness of the partition paper and filter paper when assembled. For example, The standard folding number of a wooden frame (610*610*120) mm filter is: first remove the thickness of the wood board on both sides, then 610-(20*2)=570mm, and the number of partitions is 570÷4÷2=71.25 folds, and the result is about 70~72 folds. What are the frame and support of the filter? Answer: The frame of the filter refers to an object that holds the filter material, maintains the shape of the filter, and withstands the external force when it is applied. What is the support? The part that supports the filter material or keeps the air passage between the filter materials in a certain shape. |
