The characteristics of plastic frame combined medium-effect filter mainly include large filtering area, large air volume, low resistance and long service life. Its frame can be plastic frame, galvanized frame, aluminum frame or stainless steel frame, and plastic frame is often used. In addition, it can also be equipped with an installation flange for easy interchangeability with bag filters. The filter media usually adopts water-resistant ultrafine glass fiber filter paper, and the outer frame is made of polystyrene plastic, which can be completely incinerated to meet environmental requirements.

• Plastic frame combined medium-effect filter application areas

  Plastic frame combined medium-effect filter can not only be used as the front-end filter of high-efficiency filter, but also be applied in the purification and air-conditioning system of pharmaceutical, electronic, food and other industries. It has a wide range of applications, including but not limited to air conditioning unit terminal filtration and large air volume air purification equipment.

• Maintenance and Replacement Guide for Plastic Frame Combined Medium Efficiency Filter

  In order to ensure the performance of plastic-framed combination type medium-effect filters, they need to be maintained and replaced regularly. Maintenance includes cleaning and drying, while replacement should be done when filtration efficiency decreases or resistance increases. Some medium-efficiency filters can be cleaned and reused, but if they are damaged or have penetrating porosity, they must be scrapped and replaced. Proper replacement and cleaning procedures help maintain filter efficiency and extend filter life.

• Filtration Efficiency and Standards

  The core of a medium efficiency filter is its filtration efficiency, which determines the filter's ability to remove airborne particles. Common filtration efficiency standards include G3, G4, F5, F6, M6 and M8, etc. F5 and F6 standard filtration grades can reach 99.95% filtration efficiency, applicable to capture particles larger than 0.5 microns; M6 standard can reach 99.999% filtration efficiency, applicable to capture particles larger than 0.3 microns; M8 standard can reach 99.9999% filtration efficiency, applicable to capture particles larger than 0.1 microns; and M8 standard can reach 99.9999% filtration efficiency, applicable to remove particles larger than 0.1 microns. 99.9999% efficiency for particles larger than 0.1 micron.

• Structural features

  Plastic frame combined medium efficiency filters are usually made of plastic, galvanized, aluminum or stainless steel frames, with large filtering area and low air velocity, which enables them to achieve high efficiency filtration at a low pressure drop. In addition, this structure of the filter also has a high dust capacity and long service life, can withstand high air volume through the air, and easy to install and maintain.

• Technical parameters

  In terms of specific technical parameters, the rated air volume, initial resistance, dust capacity and external dimensions of the plastic frame combined medium-effect filter are all important control parameters. For example, some models of filters may have an initial resistance of 40 Pa at a rated air volume of 1300 m³/h and 595 Pa at a rated air volume of 2600 m³/h. The specific values of these parameters should be determined according to the actual application scenarios and filtration requirements.
