Where are the air filters sold? Where to purchase the most volume

I have used a product called Bi Dou "Yidingda", Meifeng several grades of national HV filter material, the filtration accuracy is in, and the resistance is relatively lower than that of similar high-efficiency air silver filters, see that everyone's evaluation of this brand is also good, after using it is still more satisfied, I hope it will be useful to you!

There are a lot of choices for this, where do you buy a filter, then you should also need a differential pressure and air volume transmitter, we are familiar with Naxian, welcome to communicate, Shenzhen Getu Li Jiafeng Technology.

Pharmaceutical Factory, Hospital, Electronics Factory, Aviation Technology, Shenzhou No. 11, Pig Factory. Wait a minute.

It is best to buy it in a regular 4S store.

The air filter element must not be bought casually, not only to buy the best air filter, but also to the regular flagship ** or auto parts store to buy the air filter, because there are still a lot of "sheep head selling dog meat" merchants on the market, that is, inferior products, those manufacturers in order to save costs and cut corners, not only the quality is not very good, but also there is no obvious filtration effect, so that it can not effectively protect the engine, you must know that the engine maintenance is not cheap.

The compressed air filter is a device that filters and purifies the pressurized air. Generally speaking, the compressed air filter element is composed of fibrous media, filter screen, sponge and other materials, and the solid and liquid particles (droplets) in the compressed air are intercepted by the filter material and condensed on the surface of the filter element (inside and outside). The droplets and impurities accumulated on the surface of the filter element are precipitated by gravity to the bottom of the filter and then discharged through the automatic drain.

Compressed air filter classification:

Generally, the grades of compressed air filters can be divided into pre-filtration, primary filtration, fine filtration and activated carbon filtration. Among them, the pre-filter generally removes particles with a diameter of 3-5um, and the primary filter generally removes particles with a diameter of 1ppm w wActivated carbon filters are mainly used to remove odours and oil vapours (the residual content of oil mist is only w w).

DPC Compressed Air Filter Applications:

Pre-filters are generally used downstream of compressors (aftercoolers) and are not used in demanding applications. Primary filters are generally used for tools, motors, cylinders, etc. Fine filters are generally used in painting, injection molding, instrumentation, control valves, transmission, stirring, electronic component manufacturing, nitrogen separation, etc.

Activated carbon filters are generally used in food and pharmaceutical manufacturing, breathing air, gas processing, etc.

Relationship between compressed air filter efficiency and air temperature:

The temperature of the oil and water contained in the compressed air affects the efficiency of the filter. For example, when the temperature is 30, the oil content flowing through the filter is 5 times that of 20; When the temperature rises to 40, the oil content flowing through the filter is 10 times that of 20.

Therefore, the filter is generally installed at the lowest temperature point of the compressed air system.

Should I describe it in more detail? According to the test I have done so far, the compressed air has oil, particles, water and other filters, where to use it? There are many, such as:

1.The function of a compressed air filter is to filter oil, water, and particulate matter from compressed air. Generally, it is divided into 3 levels for filtration.

Stage 1 mainly filters impurities in liquid form and will filter out 95% of impurities. Stage 2 generally filters out particles larger than 5 microns and most of the oil in aerosol form. Stage 3 is precision filtration, which can filter particles as small as microns and gaseous oils.

2.The three most important points to pay attention to during the use of the filter are: sizing, blowdown and differential pressure.

3.If the factory has just been put into operation and the flow rate is relatively small, it is extremely unreasonable to reduce the diameter of the pipe and then equip it with a filter with a diameter smaller than the size of the pipe. Because it will cause a large pressure drop, and at the same time, once the production is increased in the later stage, the air consumption will increase, the filtration effect will be greatly reduced, and the quality of compressed air cannot be guaranteed.

4.The filtered impurities need to be discharged through the sewage system in time to ensure the normal operation of the filter. The best way is to equip the filter with an automatic sewage discharge device to reduce the untimely sewage discharge caused by human factors.

5.The filter element is a consumable, when the pressure difference between the front and back of the filter reaches a certain value, the filter element must be replaced to ensure the filtration effect, but also to prevent the powder from flying out due to damage to the filter element and contaminating the compressed air pipe network. In many cases, the field relies on experience to replace the filter element, such as 3 months, 6 months.

This practice is unscientific, because the degree of blockage or damage of the filter element is related to many factors in addition to time, such as the flow rate, the cleanliness of the inlet gas, and the working condition of the sewage system. The more scientific approach is to set a limit value for the differential pressure and replace it immediately when the pressure difference limit is reached.

Test items of compressed air filter:

Primary purification efficiency (particulate matter, gaseous pollutants, microorganisms), dust holding capacity, guessing resistance, ozone, etc.;

Detection standard of air spike trapping filter:

GB T 14295-2008 Air filter.

You can take a look at Zhongke Testing, and the qualification projects are complete"

Compressed air filter filtration efficiency Biyan test report. General air conditioning manufacturers can do source change. Such an inspection report, many air conditioning manufacturers can make repentance.

You can go to the Administration for Industry and Commerce and the Consumer Association to complain directly, there is no need to be so troublesome, you just have to go, and Shangjia Wuxin will solve your problem, because he is afraid of affecting his reputation.

The mechanical efficiency test report of the compressed air should have some special institutions, and this should be customizable.

The risk coefficient level of different occupations is high and low, and it is divided into: life insurance risk level, comprehensive macro risk risk level, hospitalization insurance risk level and allowance risk level four categories generally divide all types of work occupations in the current society into 6 risk levels, the lowest level, the safest, all insurance is applicable (such as enterprises, institutions, unit supervisors, administrative office personnel, etc.), 6 levels of the most concealed and high, that is, the most dangerous occupational category, part of the insurance is prohibited from insurance (smelting, manufacturing, Front-line workers such as construction and other special industries) The insured is limited to persons in categories 1-4, which means that occupations 1-4 can be insured, and occupations 5-6 are prohibited. There are currently nearly two or three thousand occupations in society, and there is no way to elaborate here.

A small white hole about 1 mm in size can be seen in the disc body, which is where the air filter is located.

Air filters are widely used in various local purification equipment and clean workshops. The purification of air under normal temperature, normal pressure and normal humidity conditions is used as the pre-filtration of high-efficiency air filters to reduce high-efficiency air.
