• High efficiency, low resistance, large dust capacity: the main feature of the knife frame high efficiency filter without partition is its high efficiency filtration capacity. It can effectively intercept airborne particles above 0.3μm, with a filtration efficiency of over 99.99%, and some models can even reach 99.999%. At the same time, due to the partitionless design, the filter has lower resistance and a large dust holding capacity, which means that more dust particles can be handled under the same conditions, prolonging the service life of the filter.

• Easy installation and good sealing performance: The design of the knife-rack partitionless HEPA filters allows for quick and easy installation, which can be accomplished without complicated tools. In addition, the use of special sealant on the outside of the filter ensures good sealing performance and reduces the risk of leakage, thus guaranteeing filtration efficiency.

Application Areas

Knife rack type high efficiency filter without partition is suitable for a variety of occasions, especially for pharmaceutical factories, biological factories, food processing and other places that require strict control of air pollution sources.

Installation steps

• Inspect the filter: Before installation, inspect the filter for any damage and confirm that the model specification meets the usage requirements.

• Prepare the installation area: Ensure the flatness and cleanliness of the installation location to prevent affecting the sealing performance of the filter.

• Installation of the filter: Gently place the knife-rack type non-septum high-efficiency filter in the installation position, paying attention to the correct direction to ensure the sealing.

• Sealing treatment: Use suitable sealing materials, such as silicone rubber or polyurethane adhesive, to seal the joints between the filter and the frame.

• Inspection and testing: After the installation is completed, the filter should be inspected for sealing and performance testing to ensure that it meets the use standard.

Use and Maintenance

• Regular inspection: Regularly check whether the filter is clogged or damaged, and clean or replace the filter material in time.

• Avoiding moisture and pollution: In the process of use and maintenance, the filter should be avoided from contacting moisture and other possible pollutants.

• Professional training: Operators should receive relevant safety training and understand the correct use and maintenance methods.

• Design Characteristics

  Knife frame high efficiency filter without separator is a kind of high-efficiency air filtration equipment, which is mainly used to filter air suspended particles above 0.3μm, and is widely used in the end filtration of various filtration systems. The filter is made of ultra-fine glass fiber filter paper with hot melt adhesive as the separator. This design not only reduces the running cost, but also ensures optimal airflow through to achieve a high dust holding capacity, making full use of the filter media throughout the entire depth of the filter. In addition, the filter is sealed all around with a special sealant to ensure the sealing of the entire filter, and plastic sprayed guards are added to the inlet and outlet surfaces to protect the filter paper from damage. Each filter has been strictly tested and has the filtration efficiency of H13 and H14 level.

• Material composition and operating conditions

  The filter media of knife frame high efficiency filter without partition is mainly composed of ultra-fine glass fiber filter paper, using PU two-component polyurethane AB adhesive as sealant, the frame material is usually aluminum profile frame, the protective mesh is sprayed rhombic mesh, the separator is EVA hot-melt adhesive, and the sealing strip can be used as EVA or neoprene rubber. In terms of operating conditions, the filters can be operated at temperatures of up to 70°C and humidity of up to 80%.

• Product dimensions and specific parameters

  The product dimensions and parameters of the knife frame type high efficiency filter without partition include different specification sizes, rated airflow, filter area, dust holding capacity and resistance. For example, the 320320110mm size filter has a rated airflow of 400m³/h and a dust holding capacity of about 250g, with resistance ranging from 400-600Pa, While level H13 has a filtration efficiency of 99.97-99.99%@0.3μm, level H14 has a filtration efficiency of 99.995-99.999%@0.3μm.
