Main Performance Characteristics

• High-efficiency filtration capacity: The filter is capable of capturing particles of dust and suspended matter with a size of 1-5 microns, and the filtration efficiency is as high as 60% to 95% (based on the colorimetric method).

• Large air volume and low resistance: Even when processing large amounts of air, the resistance can be kept low, ensuring system energy efficiency and stable operation.

• High Dust Capacity & Cleanability: Design allows the filter to accumulate a high dust capacity and can be reused by cleaning, reducing maintenance costs.

• Diverse structural forms: Frameless and framed bag designs are available to suit different installation and application scenarios.

• High-quality filter media: The use of special non-woven fabrics or glass fibers as filter media ensures filtration stability and durability.

• High temperature and humidity resistance: can work stably for a long time in temperatures up to 80°C and 80% humidity environments.

Unique technical highlights

• Ultra-fine glass fiber meltblown media: with tiny fiber diameters (0.5-5 microns), it provides high filtration efficiency and low resistance, while equipped with a chemical fiber protective lining to prevent media damage.

• Optimized filter bag structure: The use of gradual line spacing sharp edge technology to form a uniform “V” channel structure ensures that the air passes through the filter media layer uniformly, improving filtration efficiency and prolonging service life.

• Fire safety: Comply with UL-2 fire rating standard of the U.S.A. Hi-Flo filters with UL-1 rating are available for some special applications.

• International certification: Passed the TUV international environment and health certification and third-party authority VTT test, in accordance with EN 779 and Eurovent 4/9 standards, to ensure the global applicability and safety of the product.

• Installation and Maintenance

  When installing the Combined Activated Carbon Medium Efficiency Filter, make sure that the filter is placed smoothly in the ventilation system and that all connecting parts are well sealed to avoid leakage of unfiltered air. Regularly check the sealing and fixing condition of the filter and adjust or reinforce it if necessary.

• Replacement and Cleaning

  Depending on the cleanliness and air quality of the environment in which it is used, the activated carbon layer and filter bag in the filter should be replaced regularly. When replacing, make sure to use accessories that match the original filter to maintain the best filtration effect. When cleaning the filter bag, follow the manufacturer's instructions and use suitable cleaning agents and methods to avoid damaging the filter bag material.

• Performance Monitoring

  Periodic monitoring of air quality before and after the filter is recommended to assess its filtration effectiveness. This helps to identify potential filtration problems in a timely manner and ensures that the system continues to operate at optimum conditions.

• Safety Precautions

  When operating and maintaining the filter, follow all safety procedures and use appropriate personal protective equipment to prevent exposure to hazardous substances or accidental injury.

• Equipment composition and structure

  The combined activated carbon medium-effect filter consists of several activated carbon filters. Each filter is filled with granular activated carbon as the adsorption substrate, and adopts black non-woven fabric as the cover, and is supported by sprayed plastic wither-shaped protective net on both sides. These activated carbon filters are placed in a “V” shaped structure inside the outer frame, and sealed with PU polyurethane adhesive between the frame. This design ensures the stability and durability of the filter.

• Function of activated carbon

  Activated carbon, with its high carbon content, greatly improves the filter's ability to remove odors and extends the service life of the filter. The adsorption properties of activated carbon enable it to effectively remove a wide range of harmful gases and particles from the air, thereby protecting the environment and human health.

• Medium Efficiency Filter Standards

  In China, the standards for medium-efficiency filters are set and regulated by the State Administration of Quality Supervision, Inspection and Quarantine (now the State Administration of Market Supervision and Administration). Medium-efficiency filters are required to pass a series of tests to verify their filtration performance, including wind resistance test, particulate capture efficiency test, and moisture resistance test. Only those medium-efficiency filters that meet the standard requirements can be certified, sold and used in the market.
