Centrifugal air filter main buyer country

When they talk aboutmain buyer countriescentrifugal filters, the template “Europe and the USA” immediately pops up, but in reality the picture is more complicated - for example, in Germany they prefer multi-stage systems, but in Poland or Turkey the demand for simple centrifugal models for agricultural greenhouses is growing. My experience shows that the key factor is not so much the geographical location, but the type of object and the budget of the project.

Peculiarities of demand in different regions

Last year we throughShandong Linyao Intelligent Agriculture Technology Co.,LtdWe supplied a batch of filters to Kazakhstan - there it turned out that not only the quality of cleaning was important, but also resistance to voltage surges. Local engineers directly said: “Our electricity stability is worse than in your technical specifications.” We had to modify the control unit, although initially the project seemed standard.

But in Belarus they were faced with another problem: customers demanded confirmation of compliance not only with the technical regulations of the Customs Union, but also with some internal standards of farmer cooperatives. It turned out that their specialists had been using outdated methods for calculating throughput for years - they had to conduct a full-fledged seminar with field tests.

It is interesting that on the website https://www.lyzhihuinongye.ru we initially posted only general characteristics of the equipment, but after requests from Uzbekistan we added a section with adaptation to high sand content in water. This is exactly the case whencentrifugal air filtermust work in conditions that are rarely described in textbooks.

Technical nuances when working with different climates

In projects for the Krasnodar region, it was necessary to completely reconsider the body material - ordinary steel was quickly covered with condensation, which led to corrosion of fasteners. We switched to composite polymers, although this increased the cost by 15%. By the way, it was then that we began to work closely with engineers fromShandong Linyao Intelligent Agriculture Technology Co.,Ltd— their experience in the design of hydraulic structures turned out to be irreplaceable.

For the northern regions of Russia, we had to develop a heating system for the inlet pipe. It would seem like a trifle - but without this, at -30°C, the centrifuge blades simply could not create the required air flow. Moreover, at first they tried resistive heating, but it consumed too much energy - in the end they settled on a heat exchanger from a running engine.

The most difficult thing is when the customer himself does not fully understand the operating conditions. There was a case in Moldova: a farmer insisted on a standard model, but after installation it turned out that his system had constant water hammer due to an old pump. The filter worked, but the service life was halved - we had to urgently install an additional receiver.

Economic aspects of equipment selection

I often see buyers focusing on the initial cost while completely ignoring the operating costs. For example, cheap Chinese analogs require replacing seals every 3-4 months, while our models fromShandong Linyao Intelligent Agriculture Technology Co.,Ltdwork for 2-3 years without intervention. But explaining this to an accountant who sees only the price tag is a separate science.

In general, the situation in Serbia is interesting: there is a strong influence of local distributors who increase prices by 40-50%, arguing that this is “European quality.” At the same time, technically our filters are often superior to their Italian counterparts, but it is difficult to break through this price barrier - we have to work through direct contracts with agricultural enterprises.

I noticed a clear correlation: in countries with developed crop insurance (such as Croatia), clients are willing to pay for reliability, and where agricultural producers work 'for luck', they save on everything. This also affects the requirements for filters: in the first case, a two-fold security system is needed, in the second, a minimally efficient option.

Design and installation errors

The most common problem is incorrect performance calculations. Once in Bulgaria they installed a filter designed for clean water in a system with an open reservoir - after a week the impeller was broken by small stones. We had to urgently develop a pre-filter settling tank, although the project had already been completed.

It’s even worse when installers skimp on piping. In Romania I saw how flexible hoses were connected to the filter instead of rigid pipes - the vibration destroyed the flange connection in six months. Although the instructions say in black and white about the need for hard eyeliner.

By the way, about instructions: on the website https://www.lyzhihuinongye.ru we now post not only standard manuals, but also cases with unsuccessful installations - this helps to avoid repetition of mistakes. It is especially useful for countries that do not have their own certified specialists.

Prospects for technology development

We are now actively experimenting with pollution control sensors - the idea is that the filter itself will determine the need for washing. But so far, optical sensors are too capricious for field conditions, and strain gauge sensors are expensive. Perhaps in a couple of years a budget solution will appear.

An interesting direction is the combination of centrifugal purification with electrostatic pre-filtration. This is especially true for livestock farms, where there is a lot of organic dust in the air. Trial tests on siteShandong Linyao Intelligent Agriculture Technology Co.,Ltdshowed an increase in efficiency by 18-22%, but it is not yet clear whether such a complication of the design will pay off.

The main challenge is not technical, but psychological. Many farmers still consider air filters overkill, especially in countries with low labor costs. It is necessary to prove that the costs of frequent replacement of filter elements in ventilation systems ultimately exceed the cost of a centrifugal filter. And here it is important which country the buyer is from - in developed agricultural regions they already understand this, in developing regions they are just beginning to realize it.
