• Dust trapping capacity: able to effectively trap dust particles of 1-5μm.

• Filtration efficiency: depending on the model, the filtration efficiency varies between 60%-95%.

• Structural Stability: Adopting hot melting process, the structure is stable and reduces the risk of breakage and leakage.

• Air volume and resistance: large air volume and low resistance, suitable for large area air filtration.

• Dust holding capacity: with a large dust holding capacity, it can be cleaned and used repeatedly.

• Material diversity: the filter material is mostly special non-woven fabric or glass fiber, and the frame can be cold plate spraying, galvanized plate and other forms.

• Wide application: Widely used in central air-conditioning, pharmaceutical, hospital, electronics, food and other industries.

Application of Medium Efficiency Filter

• Because of its high efficiency filtration capacity and large air volume, the plastic frame combined medium-effect filter is commonly used in air-conditioning systems and centralized air supply systems, and it is especially suitable for intermediate filtration of air in industries such as pharmaceuticals, hospitals, electronics and food. In addition, it can also be used as the front-end filtration of high-efficiency filters to reduce the burden of high-efficiency filters and prolong their service life.

• It is used as an intermediate filter in central air-conditioning systems to protect the lower filters in the system and the system itself.

• In the pharmaceutical industry, it is used to maintain a sterile environment and prevent contamination.

• In hospitals, especially in clean rooms such as operating rooms, to ensure the cleanliness of tlectronics manufacturing industry, to filter dust, bacteria and other impurities and reduce defects in electronic products.

• In food processing, prevent food from being contaminated and maintain food safety.

The maintenance and upkeep of the medium-effect filter is very important to extend its service life and maintain the filtration effect.

• Regularly check the inlet surface of the filter for any debris blockage, and the surface of the filter media for any damage.

• Replace the filter regularly, generally recommended every 3-6 months or when the resistance increases by 30%.

• When cleaning, use water or neutral detergent, avoid using strong acid and alkali.

• When storing, it should be placed in a dry, dust-free environment, avoiding sunshine and rain.

• Structure and material

  The structure of plastic frame combined medium efficiency filter mainly consists of filter media, outer frame and sealing material. The filter media is usually made of synthetic fibers, such as non-woven fabrics or glass fibers, which can effectively filter dust particles of 1-5 μm, and the filtration efficiency is generally between 60% and 95%. The outer frame section can be made of plastic frames, galvanized sheets or aluminum alloy profiles to ensure a sturdy and stable structure. The sealing material is responsible for ensuring that the filter is sealed during installation to prevent air short-circuiting.

• Parameter description

  The parameters of the plastic frame combined medium-effect filter mainly include filtration efficiency, rated airflow, initial resistance, dust capacity and external dimensions. Filtration efficiency refers to the ability of the filter to remove particles in the air under a specific air volume, and the common efficiency levels are F5, F6, F7, F8 and F9, etc. The rated air volume indicates that the filter can remove particles in the air under the standard air volume. Rated air volume indicates the air flow rate that the filter can handle under standard conditions, and the unit is usually cubic meters per hour (m³/h). The initial resistance refers to the initial resistance when the filter is new, while the dust capacity reflects the dust holding capacity of the filter at the rated airflow. The external dimensions are customized according to specific needs, including the length, width and depth of the filter.
