Structural characteristics

The structure of plastic frame combined medium-effect filter is characterized by its special construction, which usually consists of plastic frame, aluminum alloy frame, galvanized frame or stainless steel frame, and the interior is filled with high-quality filtration materials, such as non-woven fabrics, glass fibers, etc. These filtration materials can effectively filter 1-5um dust particles. These filter materials can effectively filter 1-5um dust particles, filtration efficiency is generally between 60%-95%, the specific efficiency level is divided into F5, F6, F7, F8, F9, etc.. In addition, the plastic frame combined medium-effect filter also has a large filtration area and low resistance, which can maintain stable filtration performance in a large air volume environment.

Efficiency optimization technology

In order to improve filtration efficiency, plastic frame combined medium-effect filters use a variety of optimization techniques. For example, some manufacturers incorporate special anti-static fibers into the filter to enhance filtration of airborne dust particles. Meanwhile, by improving the folding method and layout of the filter media, the filtration resistance can be further reduced and the service life can be improved. In addition, new sealing technologies and materials are used to ensure a tight seal between the filter and the frame to prevent air leakage.

Application Cases

In practical applications, plastic frame combined medium-effect filters are often used in the intermediate filtration of air conditioning systems, especially in the pharmaceutical industry where the requirements for a sterile environment are extremely high, or in hospital operating rooms, food processing and other places where a certain degree of cleanliness needs to be maintained. For example, in some pharmaceutical factories, in order to ensure a sterile environment for drug production, these filters are used as key purification equipment. In hospital operating rooms, medium-effect filters are key to maintaining the cleanliness of the indoor air.

Maintenance and Replacement Guide

Maintenance and replacement of plastic-framed combination type medium-effect filters is critical to ensure their continued effectiveness. Regularly check the surface of the filter for clogging of debris and clean or replace as necessary. When cleaning, use a neutral detergent and rinse thoroughly. If the filter is damaged or becomes less efficient, it should be replaced in a timely manner. When replacing, choose a new filter that matches the model and specifications of the original filter and ensure proper installation.

Service life and replacement cycle

The service life and replacement cycle of medium-effect filters depend on a variety of factors, including the design of the filter, the environment in which it is used, and the state of maintenance. It is usually recommended to replace the filter every 3 to 6 months and clean it at least once a year to keep its filtration efficiency and resistance loss within the normal range.

Installation and Maintenance

When installing, it should be ensured that the performance index of the filter equipment meets the requirements for on-site use and is correctly installed according to the direction of air flow. For maintenance, the status of the filter should be checked regularly and replaced or cleaned in time to ensure the performance and prolong the service life of the filter.

Filtration efficiency

The filtration efficiency of plastic frame combined medium-effect filters is usually categorized into several grades, such as F5, F6, F7, F8 and F9, which represent different filtration capacities. For example, F6 grade filters are able to capture particles with diameters between 1~5 microns, and their filtration efficiencies can reach more than 60%~80%.

Wind resistance test

Wind resistance test is an important part of evaluating the performance of medium efficiency filters, which can reflect the resistance of the filter to air flow. The result of wind resistance test usually affects the use conditions of the filter, for example, if the wind resistance test is qualified, the filter can operate normally under the specified wind speed and resistance.

Moisture resistance test

The moisture resistance test of medium efficiency filters is to verify that the filters can still maintain good filtration effect under humid environment. This is especially important for applications that are used in humid environments or require high filtration efficiency.

Materials and Construction

The structural design of plastic-framed combination medium-effect filters usually takes into account the expansion of the filtration area and the reduction of resistance. For example, a V-shaped structure can significantly increase the filtration area while maintaining a low resistance, which is particularly suitable for high air volume environments.
