Air filter resistance (air filter applications)

Air FilterThe resistance of the (Air Filterapplications)

Air filter resistance

Resistance literally means the force that prevents an object from moving and is called "resistance". Are you experiencing resistance when using an air filter? Resistance is a factor that affects expression. When using an air filter, the flow of air through the filter tissue is called resistance. Depending on the amount of dust that accumulates in the filter, the resistance will increase.

The resistance of a new type of air filter in its initial use is the initial resistance, as opposed to the resistance of a filter at the end of its life (when it reaches the end of its life), which is the final resistance. For example, primary and intermediate filters have a final resistance that is twice the initial resistance. The final resistance of high-efficiency filters is 2-3 times the initial resistance. Many air-conditioning equipment, are used in the primary filter or intermediate filter to do pre-filtration, high-efficiency to do the end of the filtration. This is to better protect the high-efficiency filters, primary filters first filter large particles of dust, reduce the amount of dust on the high-efficiency filter suction, to extend the service life. Filter dust increases, the resistance increases, when the resistance reaches the final resistance, too much resistance will make the filter is captured by the formation of flying dust secondary pollution, in order to avoid the occurrence of such a dangerous event, the filter should be replaced in time when the final resistance reaches the filter. Air filters are generally recommended by manufacturers 3-6 months for a change, the specific time also depends on your frequency of use and use of the environment, some of the harsh environment and high frequency of use of the work area of the total resistance of the filter may reach the month, this month to replace the filter.

The resistance of air filters is directly proportional to the wind speed, the greater the resistance of the wind speed. When we buy air filter products, there will be a certain resistance value in the product introduction. A new product final resistance value, the greater the initial resistance coefficient, the longer the service life. Kang Guan editorial on the resistance of air filters to explain, I hope to help you better choose air filter products.

Air Filter Applications

I. Requirements for the use of bag-type medium-effect filters

(1) Commonly used filter materials for high-efficiency air filters include ultra-fine glass fiber and so on.

(2) The main control parameters for the selection of high-efficiency air filters are filtration efficiency, rated air volume, initial resistance, dust capacity and so on.

(3) The air filter should meet the fire prevention requirements, and the high-efficiency air filter is divided into three levels according to the degree of fire resistance: Level 1 filter, the filter materials are all non-combustible materials, and the non-combustible materials must meet the GB8624-1997A level. The filter material of Grade 2 filter should be GB8624-1997 Grade A non-combustible material, and the divider and frame can meet the requirements of GB8624-1997 Grade B2.

(4) High-efficiency air filter is a high-efficiency air filter, according to GB/T6165-1985 "high-efficiency air filter performance test methods through the rate and resistance" in the method specified in the transmittance rate of ≤ 0.1% (i.e., the efficiency of ≥ 99.9%) or particle size ≥ 0.1μ m particles of transmittance ≤ 0.001% (i.e., the efficiency of ≥ 99.9991 TP3T) as high-efficiency air filters.

Second, the primary filter product characteristics

(1) Product process: High-performance hot melt method is used to process organic synthetic fibers without breakage.

(2) Sticky treatment, the filter material is fully impregnated with glue, because the sticky agent penetrates into the media, so that the dust particles can not pass through, so that the whole filtered air airflow spreads evenly, forming a laminar flow state, to achieve the best spraying effect.

(3) Full adhesion, surface adhesion, and dry treatment of the filter material can be selected by the customer.

Function: This series of top surface is mainly used in the surface spraying industry, designed for the end filtration of the spraying room, which can filter out all the particles that will damage the quality of the spraying paint.

(5) Conforms to European standards DlN53438-F1 and UL900-class2 for fire classification.

(6) It can be used with outer frame to make plate filter.

(7) Incremental structure: using gradually encrypted multi-layer technology, i.e., the density of fibers in the pure air gradually increases, the filtration efficiency is higher, and can be separated into layers of different densities according to the size of the dust, which can accommodate more dust more effectively.

(8) Specifications: standard 1.0 * 211.6 * 212.0 * 21 can be customized according to the need for a variety of specifications and thickness.

(9) The air outlet surface of the filter is particularly dense, and a layer of chevron mesh is added to strengthen the shaping, this structure enables the filter media to maintain a high filtration efficiency and dust capacity, and at the same time extends the service life of the filter media, and in the use of the C-600G and C-560G, in addition to guaranteeing good air quality, the resistance of the filter media itself is relatively low, which saves the system operating costs.

Third, the application of the primary filter

(1) Used for filtering air in painting workshop, paint spraying room, baking paint room, etc.

(2) It is suitable for automobile factory, automobile repairing factory, motorcycle factory, bicycle factory, household appliances, electronic painting system.

Above is our introduction to the use requirements, product characteristics and uses of bag type medium efficiency filter, we hope that through our introduction, we can bring you some help. At the same time, if you still do not understand the place, you can always call for advice.
