Comparative analysis with high efficiency filters

The primary advantage of the plastic-framed combination medium-effect filter over high-efficiency filters is its lower cost and moderate filtration efficiency. While they may not be as efficient as HEPA filters, they provide continuous filtration over a wider range of applications and typically have a longer service life. In addition, plastic-framed combination MEP filters are easy to install and maintain, which reduces operating costs to a certain extent.

Performance Characteristics

• Particle trapping capacity: Plastic frame combined medium-effect filters can effectively trap particles of dust and various suspended matters of 1-5 microns, guaranteeing the cleanliness of the air.

• Large air volume: these filters are designed to handle a large amount of air flow to meet the demand for air volume in different environments, especially suitable for air purification equipment with large air volume.

• Low resistance: the use of special structural design makes the resistance of the filter low, which helps to reduce energy consumption and operating costs.

• High dust holding capacity: High dust holding capacity means that the filter can continue to operate without frequent replacement, increasing its service life.

• Reusable for repeated cleaning: Filters designed with some materials support reuse after regular cleaning, further reducing the use of consumables and disposal costs.

• Various types: including frameless type and framed bag type, which can be selected according to different installation and use requirements.

• Filter material: special non-woven fabrics or glass fibers are usually used as filter materials, which have good filtration performance and stability.

• Filtration efficiency: generally between 60% and 95%, depending on the filter model and application scenario.

• Applicable temperature and humidity: most of the plastic frame combined medium-effect filters can work normally at temperatures up to 80°C and 80% humidity.

• Working Principle and Application Examples

  The working principle of the plastic frame combined medium efficiency filter is to effectively capture dust particles of specific sizes through special filter media structure and design. For example, certain models of filters can capture particles of dust below 0.5um and a variety of suspended matter, which makes it widely used in industries such as electronics, pharmaceuticals, and food. Its structural design usually includes a plastic, galvanized, aluminum or stainless steel frame, as well as an internal cartridge, which consists of multi-layer fiber materials with high filtration efficiency and a large filtration area.

• Application Scenario

  Plastic frame combined medium-effect filters are not only suitable for the above mentioned industries, but also can be used as pre-filters for air filtration equipment in buildings, providing protection for high-efficiency filters and ensuring the efficiency and reliability of the whole filtration system.

• Maintenance and Replacement

  In order to maintain the best performance of the filter, it needs to be cleaned and replaced regularly. For cleaning, neutral detergents should be used and the filter should be thoroughly dried after cleaning. The replacement cycle is generally recommended to be 3-6 months, depending on the environment in which the filter is used and the operating conditions.

• Filter resistance

  According to the search results, the resistance of the plastic frame combined medium-effect filter is designed within the specified range, the initial resistance should not be greater than 0.3MPa, and the final resistance should not be greater than 0.6MPa. This design ensures that the pressure loss of the filter in the whole process of using the filter is controlled within a reasonable range, which not only ensures the filtration efficiency but also does not overly increase the operating cost of the system.

• Filtration efficiency

  The filtration efficiency of the plastic frame combined medium-effect filter is the key parameter to measure its filtration capacity. Depending on the application requirements, the filtration efficiency generally ranges from 60% to 95%. This parameter determines what percentage of particles of a given size can be effectively captured by the filter to maintain air quality.

• Symmetrical mounting and airflow balance

  In order to ensure uniform airflow through the filter, plastic-framed combination filters need to be symmetrically mounted and have a balanced airflow between the inlet and outlet ports. This is essential to maintain stable operation of the system and is the basis for achieving the desired filtration effect.

• Sealing performance

  In the process of use, the plastic frame combined medium-effect filter should maintain good sealing performance, no leakage phenomenon. Good sealing performance can prevent unfiltered air from bypassing the filter and entering the system, ensuring the filtration effect.

• Stability of frame and outer frame

  The frame and outer frame of the filter need to have sufficient strength and stability to withstand normal working pressure and possible vibration. This is usually achieved by using high quality materials such as galvanized sheet metal, ABS plastic or stainless steel.

• Regulating Valve Settings

  In order to meet different airflow requirements, the inlet and outlet of the plastic frame combined medium efficiency filter should be equipped with easy-to-operate adjustment valves. This allows easy adjustment of the filter to optimize its performance under different working conditions.
