Core Tip: Editor's Note: In recent years, as an important part of the machinery industry, the compressor industry, along with the development of the national economy and the promotion of social progress, has been rapid growth, at the same time, the compressor models in the field of practical applications also appeared to be more clearly differentiated, and their respective advantages are also gradually revealed. About the supporting products of the air compressor, at present the overall view, also basically realized the localization, but for the three filter this piece, the quality is uneven. From the point of view of the industry's life cycle, the domestic filter market is in the integration of the product level tends to mature. In the process of maturity, there will be a lot of technological innovation ideas!

About the supporting products of the air compressor, at present the overall view, also basically realized the localization, but for the three filter this piece, the quality is uneven. From the point of view of the industry's life cycle, the domestic filter market is in the integration of the product level tends to mature. In the process of maturity, there will be a lot of technological innovation ideas, competition will intensify. Therefore, for this kind of filter products with high technical content, technological innovation, product improvement is very important.
So, in the face of such a status quo, we have to understand from what aspects of the three filter? Industry insiders for the development of the compressor three filter and how to think about it? This issue of the Forum, let's listen to the netizens to start a heated discussion on it!
Wide participation, sincere exchanges, many difficulties and problems will be solved, this is the power of the network.

Ladies and gentlemen, because of my work, I have dabbled in the three filters of compressors. In my opinion, the domestic market share of MANN's three filter quality * good, the United States and Italy's second, domestic products can not be compared with it. If there are professionals who think otherwise, I hope to give you advice.

I have to say, there are a lot of imitation substitutes for domestic products, they have the shape of the big brands, but not the god of the big brands! Certain products don't even have a shape. For example, Tianjin and Wuxi have a few in the empty cartridge inside the support steel wire, pretending to be metal-free cartridge, funny ah!
ID: fxl977
Is not the domestic cartridge can not be used?! Do not always say that the foreign moon is fuller than China ah.
ID: dannyw
Oh, the moon regardless of China and foreign only one, but the product is really different. What is the accuracy of your air filter? How long does it last? By the way, how is the effect of your oil separator core?
ID: fxl977
The accuracy of the air filters I use come in 10-25 micron varieties, and the local air quality has an effect on longevity. The oil separator cartridge works fine, usually lasts 4000 hours or more.

I personally also feel a little foreign favoritism, not necessarily foreign is good ah! I also do compressor, our company is a domestic three filter. Use down is very good ah! Feeling there is no place inferior to foreign.
ID: skytian
Yes, I also think so, domestic development is now very fast, not necessarily inferior to foreign products ah.
ID: iaini
I've been in the screw compressor business for about 2 or 3 years now. When I first started in this industry, I was in direct contact with the purification equipment in the compressor. I am Chinese, so I like to use our products. In the beginning, I also used foreign products. However, their products also have oil leaks and are expensive. To be honest, who doesn't want good quality products at a fair price, right?
In the domestic manufacturers of purification equipment, I came into contact with a domestic Shanghai compressor purification equipment limited company's three filters, I personally feel that their quality is undoubtedly, the price is reasonable. So, do not always revere foreign names Oh.
Open your eyes to look at our own country's products, you will have an accident.
ID: dannyw
A foreign brand air filter: 2-3 micron, 99.9% filtration, ordinary working conditions life of about 3000 hours; a domestic brand air filter: 10-25 micron, life of about 500-1000 hours or so - these two products, is the same moon? Colleagues of the ultra-filtration, do not use the banner of the national brand, fish-eye to mix pearls! Of course, I personally am not saying that domestic products will never catch up with imports, but it takes time, institutions, national strength and national quality development. It is not by shouting slogans and pitfalls will be able to surpass the United Kingdom and catch up with the United States!
Obviously there is a gap but do not recognize, this is not an objective attitude to look at the problem oh.
ID: Yi Aini
Alas, it is really powerful foreign pandering ah. Do you understand what is purification equipment, 2-3 micron, there is no air filter? Only high efficiency is ah.
ID: boss
Quality and quality is comparable, I must support the national products!
ID: screw
Yes, now the quality is good, the price is reasonable, but the problem is that nowadays is not connected with a foreign brand, customers do not believe you ah!
ID：mann
We might as well look at the problem from another angle, not only in the compressor industry, many domestic production-oriented enterprise development goals and slogans are; to achieve the same level of the world's developed countries, we are working tirelessly towards this goal. So, why don't we use the advanced countries of high-quality products for the Chinese industry and the world synchronization services?!
ID: sueli
To this day, many domestic brands still have a certain impact, after all, they are not yesterday's them, these companies will not be in place, but every minute and second in the progress, in constant innovation, they are in practical action to prove themselves.
ID: wdb00
Oh, here the light to say good and bad advantages and disadvantages is useless, or to the Technical Supervision Bureau testing shall prevail, regardless of the domestic enterprises, foreign enterprises products, can achieve the advertised accuracy will win!!!!

What a hustle and bustle! The Sino-foreign dispute has always seemed to be the eternal topic of the country. I have also been exposed to, and represented a variety of foreign products for many years now, and I think we should all look at things objectively. The U.S. and Germany have developed earlier than us, and it is normal that certain aspects are more advanced than China. And upstairs both sides are right, people have their own opinions, but * well not be associated with the national ethos, technical business and political separation, secondary school English teacher also taught so well.
ID：sueli
Upstairs, I admit, you said that foreign countries are more advanced than domestic development, they are much more than the domestic forward, 10 times more than. However, don't you think that the domestic development is also very fast in these years? Otherwise, why are many countries now scrambling to develop in China? To talk about technology, there is no complete, is not it? It can only be said that they are learning from each other and complementing each other's strengths.
ID: Dongzi
Although I am now using a certain foreign brand of triple filter, but I sincerely hope that in the future to use domestic products, domestic brands need to do more than just improve the quality, there is a lot of work to be done. I have used some domestic brands before, objectively speaking, there is indeed a big gap.
I hope that domestic products can reach the level of foreign countries as soon as possible, work together.
ID：Dongzi
To add, the domestic brand is not only the quality problem, there are other problems, such as many foreign companies will not sell their products directly to the compressor users, while the domestic company can not.
ID：39step
Read the posting, really learned a lot. For the air compressor three filter, the competition is quite big. So, who knows how many domestic companies do foreign brands of air compressor three filter products ah?
ID：dannyw
I remember someone had statistics, data show that the domestic production of filters are now more than three thousand manufacturers!!!! More than three thousand ah!!!!! No wonder the fakes are now rampant, there are hundreds of filter factories in Zhejiang alone. However, specializing in air compressor three filter should not be so many. In fact, those who are now making counterfeits are in the industry.

Imported and domestic, in the ring? What is the air filter used for? Just block the ash only, air filter outside the set of bags, not too good! Oil filter element is to filter oil molecules, if not for the sake of fuel efficiency, some pneumatic facilities have to add some oil? As long as the temperature is controlled, I believe the life of the oil filter can be extended.
ID：dannyw
An air filter with a cloth bag on the outside???? What about the initial differential pressure? And how much is the power loss? The air filter is used to block the ash, but this ash also has to block more block less, block big block small difference right?! If the precision of the air filter 15 microns, while the precision of the oil filter is 12-30 microns, can not filter even the smallest particles, these particles will all run to the oil! As for the oil filter, its lifespan actually depends on the strength and time frame of the filter paper after it has been soaked in lubricating oil. The general accuracy of the oil filter determines the possibility of clogging is not very likely, but rather soaked after the possibility of perforation is very large. If you come across the oil filter clogging, it means that the lubricating oil internal impurities are really too much too big. In fact, there is no such thing as imports and national products in the ring, because until now, those national products have not put the technical parameters of the original up, how to play the ring?! But we are discussing it, huh?

In fact, the air filter is nothing, its role is the main pipe air intake, air filter plug is generally dusty, with compressed air to blow a blow can be, but also continue to be able to use. But the oil separation core with the air filter can be different, separation core quality is not good, I think he must be back to affect the normal work of the air compressor. The difference between the air filter and the separator core is a lot.
ID: dannyw
This is the current understanding of many people in the industry. But here are a few points to clarify:
1. The air filter is a ** channel interception, if the precision of the air filter is not high, then a large amount of dust in the air will enter the compressor, contaminate the oil, shorten the life of the oil separator core. Fusheng in the use of domestic air filter for several years, 3.6 cubic meters and began to use MANN air filter, oil life significantly improved, which is clear evidence.
2. The oil itself is not a filter, it plays the role of separation. This means that the ability of the oil to withstand dirt is limited, but also with very expensive oil to block impurities is also too uneconomical. So we advocate customers to use the three filters together, so as to make the best use of it.
3. Use compressed air to blow, to reuse the air filter, there is a certain effect. However, it should be noted that the compressed air can not be higher than 4 bar, the direction of blowing and filtering the direction of the opposite direction of the air inlet, and remove the air filter to stop. Moreover, after blowing, the air filter cannot return to a brand new condition, but only increase part of its life. Once blowing in the wrong way, damage to the air filter, then it is not worth it.
ID: wangqi
In fact, it is not that the domestic filter element can not be used, just not as good as the imported filter element, so the domestic need to work hard ah!
ID：Shane Hu
I seriously agree with the opening statement on the quality of different filters, although I work in foreign enterprises, but I hope that domestic enterprises to strengthen technological research and development, do not always copy the shape of foreigners may not be its God, and strive for an early breakthrough in the core technology! Otherwise a ** competition until the foreign brands fully adapted to the localization of the development, by then it is too late!
