• Working Principle

  The working principle of a septum-free HEPA filter consists of four main aspects: interception, inertia and diffusion, electrostatic action, and chemical filtration. These principles work together to enable the filter to effectively capture and filter out airborne particles and pollutants, thus improving the quality of air.

• Structural Characteristics

  The structure of high efficiency filter without partition mainly consists of filter media, outer frame, sealant and partition. The filter media is usually made of ultra-fine glass fiber or polyester fiber, the outer frame is mostly made of aluminum alloy, and the sealant and separator are made of hot melt adhesive or other suitable materials. This structural design not only ensures the filtration efficiency, but also facilitates mechanized production and large-scale application.

• Performance Advantages

  The advantages of the high efficiency filter without partition lie in its high efficiency filtration performance, stable working efficiency, low operating resistance and easy installation and maintenance. Compared with the traditional partitioned filter, the partitioned filter can provide a larger filtering area and lower resistance under the same conditions, thus prolonging the service life and reducing the operating cost.

Application Fields

• Electronic manufacturing industry: used in semiconductor manufacturing, LCD liquid crystal screen production, etc., to ensure the cleanliness of the production environment.

• Pharmaceutical industry: used in hospital operating rooms, pharmaceutical production workshops, etc. to prevent contamination and ensure drug quality and patient safety.

• Food industry: used in food processing and packaging to prevent microbial and particulate contamination and ensure food safety.

• Other fields: such as bioengineering, precision instrument manufacturing, aerospace, etc., all need to rely on high efficiency filters without partitions to maintain a high standard of clean environment.

Installation and Maintenance

Correct installation of non-septum high-efficiency filters is the key to ensuring their performance. When installing the filter, you need to pay attention to the orientation of the filter, ensure the correct position of the sealing gasket, and fix it securely. For maintenance, the pressure drop of the filter should be checked regularly and cleaned or replaced when necessary to maintain filtration efficiency and prolong service life.

• Design Characteristics

  Separatorless high efficiency filter is an advanced filtration equipment, mainly used for filtering air suspended particles above 0.3um, applicable to the end filtration of various filtration systems. The main feature of this filter is that its filter media is made of ultra-fine glass fiber filter paper, with hot melt adhesive as the separator, which effectively improves the filtration efficiency and stability.

• Material and structure

  The filter media of the high efficiency filter without partition is usually made of ultra-fine glass fiber filter paper or PP filter paper, which has good filtration performance and large dust holding capacity. The outer frame is made of aluminum alloy, galvanized plate or stainless steel to ensure the solidity and durability of the structure. In addition, the filter is sealed with special sealant around the filter to ensure the overall sealing performance.

• Performance Parameters

  Compartmentless HEPA filters typically have a filtration efficiency rating of H13, H14 (EN1822), which means they are capable of capturing at least 99.99% of particles with a diameter of 0.3um and above. In addition, these filters are able to operate normally at temperatures up to 80°C and relative humidity up to 100% RH, and have a certain degree of humidity and temperature resistance.
