• High efficiency, low resistance, large dust capacity

  The main feature of knife frame type high efficiency filter without partition is its high efficiency filtration capacity and low resistance. It can effectively filter out airborne particles above 0.3μm, and the filtration efficiency is as high as 99.97%, and some models can even reach 99.9995%. At the same time, due to the adoption of a special spacerless design, the pleats inside the filter are uniformly spaced, which effectively reduces the wind resistance, thus realizing a low resistance ventilation effect. In addition, the spacerless design also increases the dust holding capacity of the filter and prolongs its service life.

• Easy installation and good sealing performance

  The knife frame, panelless HEPA filter is very easy to install and is usually equipped with standardized interfaces that allow it to be quickly integrated into existing air purification systems. It also has excellent sealing performance. The outer frame of the filter is made of aluminum profiles or other hard materials and sealed with a special sealant to ensure a tight bond between the filter and the air flow path to avoid air leakage.

• Data judgment and output

  In terms of data judgment, the knife rack type high efficiency filter without partition can judge and filter the processed data according to preset rules and conditions. These rules and conditions may involve keywords, frequency, time and other aspects, and only data that satisfy specific conditions can pass the judgment stage. As for data output, the filter is able to output the judged data to users or other systems in a variety of formats, including but not limited to text, charts, reports and other forms, to meet the needs of different users.

Installation Steps

• Preliminary preparation: Before installation, first ensure the cleanliness of the installation environment and remove any debris that may affect the sealing of the filter. Check whether there is any damage to the outer frame of the filter, and confirm that the specification of the filter matches the usage requirements.

• Inspection of the filter: Open the package and check whether there is any obvious transportation damage to the filter, especially whether the filter media part is intact.

• Installation position: Choose a suitable installation position, usually on the top or side wall of the clean room, to ensure smooth and unobstructed airflow.

• Fixed installation: Use appropriate tools to fix the filter in the predetermined position, pay attention to the installation should avoid excessive force to prevent damage to the filter media.

• Sealing treatment: Use sealant or other sealing materials to seal the joints between the filter and the installation surface to ensure good sealing performance.

• Checking the sealing: After completing the sealing, carry out a leakage test to check whether there is any bad sealing, and make adjustments or repeat the sealing process if necessary.

Precautions for use

• Direction of airflow: Make sure the direction of airflow is consistent with the arrow indication on the filter to ensure correct filtration effect.

• Regular inspection: Regularly inspect the filter, including but not limited to filtration efficiency, differential pressure and other indicators, to ensure normal operation of the filter.

• Cleaning and maintenance: Clean the filter regularly according to the actual situation to avoid excessive accumulation of dust leading to a decline in efficiency.

• Replacement tips: If the filter is found to be blackened in color or damaged, it should be replaced in time to avoid affecting the filtration effect.

• Design Characteristics

  Knife rack high efficiency filter without separator is an advanced filtration technology, mainly used for filtering air suspended particles above 0.3μm, 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 the same pleat layer spacing, which guarantees the optimal airflow through and thus achieves a high dust holding capacity, making full use of the filter material throughout the entire depth of the filter.

  The filter is sealed on all sides with a special sealant to ensure that the entire filter is airtight, and a plastic-sprayed protective mesh is installed on the inlet and outlet surfaces of the filter to protect the filter paper from damage. In addition, the air outlet side of the filter is equipped with a certain length of knife edge to increase safety. Each filter has undergone rigorous testing to ensure that its performance is up to standard.

• Filtration efficiency grade

  The filtration efficiency classes of knife-edge, panelless HEPA filters are typically H13 and H14, in accordance with EN1822. The H13 class has a filtration efficiency of 99.97%@0.3μm while the H14 class has a filtration efficiency of 99.995%@0.3μm.These high filtration efficiencies make them critical for ensuring air cleanliness in many industries.

• Material composition and operating conditions

  The filter media of knife frame type high efficiency filter without partition is mainly composed of ultra-fine glass fiber filter paper, using PU two-component polyurethane AB adhesive as sealant, and the frame material is usually aluminum profile. The protective mesh is mostly sprayed diamond mesh, while the separator is EVA hot melt adhesive, and the sealing tape can be EVA or neoprene. The filters can be used in temperatures up to 70°C and humidity up to 80%.

• Product dimensions and specific parameters

  The specific parameters of the knife frame type high efficiency filter without partition include different sizes, rated air flow and filter area. For example, the rated airflow of 320320110mm is 400m³/h, the filtration area is about 4.16m², the dust holding capacity is about 250g, and the initial resistance and final resistance are between 200-600Pa. Other specifications such as 484484110mm, 610610110mm etc. are also listed with detailed parameters, providing flexibility for different users to choose.
