ISO16890 air filter classification standard
ISO 16890 New Standard for Air Filter Classification (Classification of Air Conditioning Filters) The ISO 16890 standard differs from ASHRAE 52.2 and EN 779 in that its product class setting is determined by measuring and calculating the mass of particulate matter captured by the filter, known as the dust holding capacity.
Is there a relationship between air filter area and life?
If the selection area of the filter material in the air filter is too small or the dust holding capacity per unit area is too small, the service life of the filter will be affected. When designing, it is necessary to consider that the area of the filter material in the air filter is too small or the amount of dust per unit area is too small. It is necessary to choose a filter with a large air filter area, which can greatly extend the service life.
The replacement time of the medium-efficiency bag filter of the combined air-conditioning unit
After using the combined air conditioning unit for a long time, the medium-efficiency bag filter of the combined air conditioning unit will produce a lot of stains, impurities, dust, etc. These things will clog the filter and affect the normal operation of the combined air conditioner unit. Therefore, it is necessary to clean the combined air conditioner filter regularly. How to do it? How to determine the cleaning cycle of the combined air conditioning unit filter?
How to extend the service life of air filters in environmental protection equipment
How to adjust the service life of the air filter Users often complain that the service life of the filter is too short. There are two main reasons: First, the area of the filter material in the filter is too small or the dust holding capacity per unit area is too small; second, The filtration efficiency of the pre-filter is on the low side; in addition, user expectations for filter life are too high.
Leak detection steps for high-efficiency filters
Both filters with partitions and filters without partitions cover high-efficiency and ultra-high-efficiency levels, and both can be made of galvanized sheet, stainless steel, and aluminum alloy profiles. Paper, aluminum foil board material is folded as a dividing board.
