With its excellent filtration performance and advanced design, knife-rack, compartmentless HEPA filters have become a key device for air pollution control in a number of industries. Whether in the pharmaceutical, food processing or biotechnology fields, these filters can effectively guarantee a clean working environment, thus improving product quality and production efficiency. With the continuous progress of science and technology, the knife frame high efficiency filter without partition will continue to play an important role in the field of air purification.
Knife frame type high efficiency filter without partition has a unique design, the air outlet surface is equipped with a certain length of knife edge, and it is made of ultra-fine glass fiber filter paper. Its main structure and materials include:
Filter media: ultra-fine glass fiber with excellent filtration performance.
Frame: aluminum alloy profile, lightweight and durable.
Separator: Hot melt adhesive, ensuring equal spacing between pleat layers for optimal airflow distribution.
Sealant: Polyurethane adhesive, providing excellent sealing performance and preventing air leakage.
Protective mesh: spray-plasticized guardrail to reduce damage to the filter paper.
Filtration Performance
The filtration efficiency of the knife-rack, non-compartmentalized HEPA filter is up to 99.99% (DEHS counting method). For particles of 0.3μm, the filtration efficiency of the H13 grade is 99.97-99.99%, while that of the H14 grade can reach 99.995-99.999%. This excellent filtration performance makes it ideal for high cleanliness environments.
Knife frame design: The air outlet surface with knife opening can effectively control airflow, reduce airflow resistance and increase the dust holding capacity of the filter.
Uniform Pleat Layers: The pleat layers are equally spaced to ensure optimal airflow through the filter, thus increasing filtration efficiency.
Special hermetic sealing: polyurethane adhesive and hot melt adhesive are used for sealing to ensure the airtightness of the filter.
Protective measures: The inlet and outlet are fitted with spray-plasticized guardrails to further reduce the risk of damage to the filter paper.
Knife rack type high efficiency filter without partition is widely used in the following industries:
Pharmaceutical factories: Ensure a dust-free and sterility-free environment for pharmaceutical production.
Biotechnology: Maintain clean cell culture and laboratory environments.
Food processing: Prevent contamination of food by airborne microorganisms.
The filter is to be used under the following conditions:
Maximum temperature: 70°C, adapted to the temperature requirements of most industrial environments.
Maximum humidity: withstands up to 100% humidity, suitable for humid environments.
Aluminum profile thickness: optional thickness of 110mm, to meet different installation requirements.
