High-efficiency filtration: the knife-rack partitionless high-efficiency filter adopts ultra-fine glass fiber filter paper as the filter media, which can effectively filter particles above 0.3μm, with a filtration efficiency of more than 99.99%.

Low resistance design: the partitionless design reduces the resistance of air flow, ensuring higher air volume and lower air resistance, which helps reduce energy consumption.

Long service life: Due to the optimization of its structure, the knife frame type high efficiency filter without partition has a long service life, and generally under normal use conditions, it can maintain stable performance for several years.

Good sealing performance: the use of special sealant around the filter ensures good sealing, avoids air leakage and ensures the filtration effect.

Easy to install and maintain: the design of the knife rack type high efficiency filter without partition allows easy installation and replacement, simplifies the maintenance work and reduces the maintenance cost.

Application Areas

Knife rack type high efficiency filter without partition is suitable for pharmaceutical factories, biological factories, food processing and other places where air pollution sources need to be strictly controlled. In the medical field, it is commonly used in operating rooms, laboratories, clean rooms and other places for air purification to prevent the spread of bacteria and viruses. And in industrial production, it can be used for the filtering treatment of chemicals, liquids, gases and other substances to meet the clean requirements of the production environment.

Installation and Maintenance

When installing the knife frame type high efficiency filter without partition, make sure that the sealing at the crimp between the filter and the frame is good to prevent air leakage. Regularly check whether the air inlet surface of the filter is clogged with debris, and if there are items clogged or the surface of the filter material is damaged, it should be removed or replaced in time. Once the resistance of the equipment reaches a certain level, such as 600Pa or more, it is necessary to replace the filter with a new one during the service life.

Use term

The service life of HEPA filters is closely related to their operating conditions. Generally, they need to be replaced after about one and a half years under the conditions of rated airflow. However, if a high-efficiency filter with an efficiency of F8 or less is used as a pre-filter, its service life will be shortened.

Design features

The filter is sealed with special sealant around the filter to ensure the overall sealing, and the sprayed plastic guards are also added on the air inlet and outlet surfaces to protect the filter paper from damage. It is worth mentioning that the air outlet side of this filter has a knife edge of a certain length, which increases safety. Each filter is strictly tested before leaving the factory to ensure the quality and performance of the product. The filtration efficiency class is usually H13, H14 (EN1822).

Technical Parameters

The technical parameters of knife frame type high efficiency filter without partition include but are not limited to the material of filter media, type of sealant, using temperature and humidity, filtration efficiency and so on. The filter media usually adopts ultra-fine glass fiber filter paper, and the sealant may be PU two-component polyurethane adhesive or hot melt adhesive. The operating temperature can be up to 80°C and the humidity can be up to 100%. The filtration efficiency, on the other hand, is capable of filtering out 99.99% to 99.999% of particles of 0.3μm and above, depending on different filtration grades, such as H13, H14, and so on.
