Medium efficiency filter manufacturer

Many clients, and even some specialists, when choosingmedium efficiency filtersprone to simplifications. 'Medium effective' is considered to be somewhere between 'good' and 'poor', and is therefore suitable for most cases. In fact, this is far from the case. This class of filters is the golden mean, but in order to use it effectively, it is necessary to understand the specific tasks and characteristics of the air flow. The problem often arises from misinterpretation of specifications, as well as underestimation of the influence of other parameters of the filtration system. I will share my experience, perhaps this will help avoid mistakes.

What is a medium efficiency filter and why is it needed?

First of all, let's understand what is meant by 'average effective'filter. Typically these are filters with an efficiency class of MERV 8-13 (in the American classification) or EN 137 (in the European classification). They are designed to trap dust, pollen, small dirt particles, bacteria and viruses. They are excellent for ventilation systems in residential premises, offices, and small production workshops.

The main thing is to correctly assess the tasks. If you only need to filter out large particles, a cheaper, less efficient filter will do just fine. But if we are talking about protecting equipment from wear and tear or creating clean air in a room with increased hygiene requirements, then you need to choose a better quality one.medium efficiency filter. For example, in areas with high levels of pollution (construction, woodworking) or in medical institutions, the use of more efficient filters becomes mandatory.

The key is the balance between efficiency and air resistance. The higher the filter efficiency, the greater the airflow resistance. This, in turn, requires a more powerful fan, which increases energy costs. Therefore, when choosingmedium efficiency filter, it is important to consider the characteristics of the entire system.

Experience with various filter materials

In our practice (Tianjin Tongchang Junqi Cleaning Equipment Co.,Ltd.) we work with various typesmedium efficiency filtersmade from different materials: synthetic fibers, cellulose, polypropylene. Each material has its own advantages and disadvantages. Synthetic fiber filters are usually more durable and moisture resistant, but they can be more expensive. Cellulose filters are more affordable, but require more frequent replacement.

One day we encountered a problem during installationmedium efficiency filtersto a production workshop where there is a lot of dust. We selected polypropylene filters that we felt were ideal for these conditions. However, after just a few weeks, the filters began to quickly become clogged, which led to an increase in airflow resistance and a decrease in the efficiency of the ventilation system. It turned out that the dust present in the workshop was more abrasive than we expected, and the polypropylene filters could not withstand such intense exposure. As a result, we switched to filters with a denser structure, made of a special multilayer material. This required additional costs, but significantly improved the performance of the system.

The role of pre-filtration cannot be underestimated. The use of a pre-filter that retains large particles significantly extends the service lifemedium efficiency filter.

Basic mistakes when choosing and installing

Often errors occur at the stage of incorrectly selecting a filter based on the size and type of fan housing. The filter must fit tightly to the housing so that there are no air leaks. Incorrect installation may result in reduced filtration efficiency and increased energy consumption.

Another common mistake is ignoring the manufacturer's recommendations. Each filter has its own optimal service life and operating mode. Failure to follow these recommendations may result in premature filter wear and reduced efficiency.

It is important to remember the need for regular replacementmedium efficiency filters. The service life of the filter depends on the degree of air pollution and operating conditions. It is recommended to visually inspect the filter at least once a month and replace it if necessary.

Air resistance problems and system optimization

Increased air resistance is a common problem when usingmedium efficiency filters. It can lead to reduced fan performance, increased energy consumption, and poor air quality.

To solve this problem, you can try to optimize the ventilation system: increase the fan performance, replace the fan with a more powerful one, or change the design of the air ducts. You can also consider using more efficient filters that provide the required degree of purification with less airflow resistance. Don't forget to clean your air ducts regularly.

In some cases, to reduce air resistance, special pre-filters or modifications to air duct designs are used. For example, to reduce hydraulic resistance, you can use air ducts with a smoother internal surface.

Alternatives and new developments

New developments in the field of air filtration are constantly appearing on the market. Filters with improved characteristics are appearing, more efficient and durable. For example, activated carbon filters, which remove odors and gases from the air. Or ionization filters that help fight bacteria and viruses.

Particular attention is now paid to the developmentmedium efficiency filterswith improved stain resistance and longer service life. This is achieved through the use of new materials and production technologies. Company ?Tianjin Tongchang Junqi Cleaning Equipment? actively participates in the development and implementation of such filters.

In addition to traditionalmedium efficiency filters, there are other types of filters, such as HEPA filters and ULPA filters, which provide an even higher degree of air purification. But their use is limited to specialized tasks.
