High-efficiency filtration: Knife-rack partitionless high-efficiency filters usually have a filtration efficiency as high as 99.99% or even higher, which can effectively remove particles above 0.3μm, and some of the products are even capable of filtering 0.1μm particles, meeting the filtration requirements of H13 and H14 levels. Low resistance: the design adopts the structure of no partition, which reduces the resistance of air flow and ensures low operating resistance, which is conducive to reducing energy consumption.

Large dust capacity: the design of no partition makes the filter have a larger filtration area, which improves the dust capacity and prolongs the service life.

Good sealing performance: the use of special sealant ensures the sealing of the filter, prevents leakage and ensures the filtering effect.

Convenient installation: the aluminum profile outer frame design can be directly installed in the liquid tank sealing device, simplifying the installation process and saving time and labor.

Strong adaptability: different specifications and sizes can be provided according to different application environments and requirements to meet specific filtration needs.

Applications

Knife rack type high efficiency filter without partition is mainly used for terminal filtration of various clean plants with vertical air supply, especially suitable for pharmaceutical factories, biological factories, food processing and other places where air pollution sources need to be strictly controlled.

Structure and performance characteristics

The main features of the knife frame type high efficiency filter without partition include high efficiency filtration, low resistance and large dust capacity. The structure is designed to allow optimal airflow and is usually equipped with special sealant seals and sprayed plastic guards to protect the filter paper from damage. In addition, the air outlet side of the filter has a knife edge of a certain length, which enhances the sealing and stability.

Materials and Technical Parameters

The filter material of knife-edge non-spacer HEPA filters is generally ultra-fine glass fiber filter paper, using hot melt adhesive as the separator. Technical parameters include, but are not limited to, filtration efficiency level (H13, H14, etc.), operating temperature, operating humidity, and optional thickness of aluminum profile.

Installation and Maintenance

When installing the knife frame type high efficiency filter without separator, make sure that the sealing at the crimp with the frame is good to prevent air leakage. Regularly check whether there is any debris blockage on the air inlet surface of the filter and whether there is any damage on the surface of the filter media, and clean or replace it if necessary.

Filtration efficiency: Class H13 filters are 99.97-99.99%@0.3μm efficient, Class H14 filters are 99.995-99.999%@0.3μm efficient

Resistance: generally in the range of 0.52~1.2kPa.

Dust capacity: Depending on the specifications, the dust capacity ranges from several hundred grams to several kilograms.

Size: A variety of sizes are available to suit different installation needs.
