selectionAir FilterWhat are the considerations? What are the filter cottons in a filter?

Air FilterIs our current life is very common equipment, so we must master the correct method of selection before the usual use of the four aspects of the selection of air filters should be considered:

I. According to the purpose of filtration

The so-called purpose of filtration is only two kinds, one is to recover valuable solids, and the other is to directly purify the filtrate, according to their own practical situation to choose.

Second, according to the performance of filtration

First we need for the production of materials to be filtered have a clear understanding and understanding of the situation, you can first determine the concentration of materials, solid particles, particle size distribution, etc., according to the results of the preliminary determination of what type of filtration equipment should be selected.

III. Conditions under which the treatment

1、If the material to be filtered is more toxic, the method of airtight filtration must be used.

2, if you need to filter high temperature or toxic materials, it is necessary to choose the equipment with corrosion resistance.

3、If the temperature of the material is high, the vacuum filtration will be more difficult, you should choose the method of pressurized filtration.

IV. According to the handling capacity of the equipment

1, if the amount of material to be processed is relatively small then you can use the intermittent equipment, which is more economical;.

2, if the need to filter a large number of materials in the production of occasions, you should choose can be continuous or automated operation of the equipment.

What are the filter pads used in air filters

Filter cotton is a practical one of many filter materials, but then carefully divided into filter cotton can also be divided into synthetic fiber filter cotton, non-woven filter cotton, glass fiber filter cotton, activated carbon filter cotton four. The following small editor for you to explain the air filter used in the filter cotton which:

1.Synthetic Fiber Filter Wool

The main raw material of synthetic fiber filter cotton is polyester fiber, abbreviation abbreviation: PET, polyester fiber is made of polyethylene terephthalate, also known as synthetic fiber or polyester. Polyester has excellent wrinkle resistance, elasticity and dimensional stability, good electrical insulation properties, sunlight resistance, friction resistance, not mildewed and not moth-eaten, good resistance to chemical reagents, can be resistant to weak acids and weak alkalis. In the general filtration environment can be a multi-faceted alternative to non-woven fabrics and glass fibers to cover the coarse, medium and high efficiency of the full range of filtration products, is the emerging filter material, but also the main direction of the development of future filtration materials. Compared with other filter materials of the same level, it has the advantages of low resistance, light weight, large capacity, environmental protection (incineration) and moderate price.

2. Non-woven filter cotton

Scientific name polyester fiber, commonly known as nonwoven fabric, nonwoven fabric with the use of sex, technical maturity, stability and other technical characteristics, is China's current initial and intermediate effect plate, bag filter typical filter material. Manufacturing process to meltblown, needle punching, spunlace, spunbond and other processes made through a number of procedures, compared with other filter media of the same level has a stable quality, greater dust capacity, moisture resistance, long service life, economic durability and other advantages. Nonwoven fabric is also the application of early filtration materials, mature technological development, low production costs, in recent years, due to the continuous technology, the emergence of composite nonwoven fabrics greatly improve the image of nonwoven fabrics of cheap and low-grade in the efficiency has been able to reach the sub-high-efficiency. At the same time, composite nonwoven filter media can also be used for filtration in places with relatively high requirements for air cleanliness.

3. Glass fiber filter wool

Glass fiber filter wool is mainly made of glass fibers of various thicknesses and lengths by special processing technology. Glass fiber with its stable performance, high temperature resistance, high efficiency and large capacity, long service life and other characteristics. And in some special environments only glass fiber can be competent. It is used in primary filters, high temperature resistant filters and high efficiency filters of general ventilation systems, places and environments with high requirements for air filtration.

4. Activated carbon filter cotton

Activated carbon is characterized by the removal of odors from the air. Activated carbon filter wool is synthetic fiber treated with carbon impregnation and glue. Because the function of activated carbon is to remove odors, there is no emphasis on filtration efficiency. In use. Generally must be used in conjunction with the use of independent primary, medium and small filters.
