High dust holding capacity

The design of the Plastic Frame Combination Medium Efficiency Filter allows it to collect more dust particles without compromising performance, which means it can run for longer periods of time without requiring frequent replacement, reducing maintenance costs and time.

Low resistance, high airflow

The construction of this filter optimizes the air flow path, allowing for greater airflow while maintaining consistent filtration at lower resistance, which is critical to maintaining proper system operation.

Easy installation

Plastic-framed combination filters are often equipped with convenient mounting ports that allow for quick replacement of old filters or matching with other system components, simplifying the installation process and improving work efficiency.

Wide range of applications

Due to its excellent filtration performance, the plastic-framed combined medium-effect filters are not only applicable to pharmaceutical, electronic and food industries, but also to hospitals, cosmetics, semiconductors and precision machinery, as well as intermediate filtration in air conditioning and ventilation systems.

Excellent filter material

The use of fine glass fiber or other high-performance materials made of filter media provides higher filtration efficiency and better protection, ensuring the effective interception of fine particles.

High filtration efficiency

Depending on different application requirements, the plastic frame combined medium-effect filters can achieve filtration efficiencies from 85% (class F7) to 95%, which is especially important in high-standard clean environments.

Application Cases

Plastic frame combined medium-effect filters are widely used in different industries. For example, in the pharmaceutical industry, it can effectively filter dust and fumes in the production process and guarantee the quality of drugs. In hospital operating rooms, it can reduce the spread of bacteria and viruses and provide a relatively sterile environment. In addition, in the electronics manufacturing industry, the filter purifies the air in the production plant and prevents dust and static electricity from damaging precision electronic components.

Maintenance and Replacement Guide

Maintenance and replacement of plastic frame combined medium efficiency filters is the key to ensuring that they work effectively for a long period of time. During daily use, the differential pressure of the filter needs to be checked regularly, and once it exceeds the specified threshold, the filter needs to be replaced with a new one. In addition, the exterior of the filter needs to be cleaned regularly to remove accumulated dust and dirt. Some washable filters can be cleaned and then reused through a specific cleaning program, but more than two times is usually not recommended as filtration efficiency may be reduced.

Filtration efficiency and scope of application

The filtration efficiency of plastic frame combined medium-effect filters generally ranges from 60% to 95%, and can effectively capture particles of 1-5μm. According to different filtration efficiencies and particle sizes, medium-effect filters are categorized into F5, F6, F7, F8 and F9. These filters are suitable for capturing medium-sized particles and are suitable for use as pre-filters for high-efficiency filters to reduce the burden on high-efficiency filters and extend their service life.

Installation and Maintenance

The main point of installing the plastic frame combined medium efficiency filter is to ensure proper orientation and sealing to prevent air from bypassing the filter and causing contamination.

Structural design

The structural design of plastic frame combined medium efficiency filter includes several parts, which usually consists of plastic frame, filter material, partition and sealant. The filter material is usually non-woven or glass fiber, which has good filtration efficiency and large dust holding capacity. The design of the spacers ensures the spacing of the pleat layers inside the filter to maximize the utilization of the filter material, while the sealant is responsible for ensuring the sealing of the filter and preventing air from leaking sideways.

Construction and Materials

Plastic frame combined medium efficiency filters are mainly composed of an outer frame, filter media, partitions and sealing gaskets. The outer frame is usually made of high-quality galvanized frame or aluminum alloy frame to ensure the stability and durability of the structure. The filter media is mostly made of glass fiber or non-woven fabric, which is ultrasonically stitched and internally drawn to enhance its strength and stability. In addition, the filters are equipped with thermoplastic adhesive or other suitable sealing materials to achieve good sealing performance.

Performance parameters

The main performance parameters to be considered when selecting plastic frame combined medium-effect filters include rated airflow, initial resistance, final resistance, dust holding capacity and external dimensions. For example, the rated air volume refers to the air flow that can be handled by the filter under normal operating conditions; the initial resistance refers to the pressure loss when the filter is new; the final resistance is the expected maximum pressure loss at the end of the filter's service life. Dust capacity reflects how much pollutant the filter can hold without becoming saturated.
