Working Principle

The main working principle of the knife-rack type high efficiency filter without partition is to achieve effective filtration of airborne particles by means of specific filter materials, such as ultra-fine glass fiber filter paper, combined with hot melt adhesive or other sealing materials. The design allows air to flow while minimizing the passage of particles, resulting in highly efficient filtration.

Performance Characteristics

• High filtration efficiency: the filtration efficiency for ≥0.3μm particles is above 99.9995%.

• Low resistance: low wind resistance helps to reduce energy consumption and improve the operating efficiency of the system.

• Large dust capacity: It can hold more dust particles without affecting the filtration efficiency, which prolongs the service life.

• Light weight: Lighter weight facilitates installation and transportation, and also reduces the burden on the supporting structure.

• Low running cost: Considering its high efficiency filtration performance and low wind resistance, it makes its energy consumption and maintenance cost relatively low in the running process.

Areas of application

• Pharmaceutical factories, biological factories, food processing and other places that require strict control of air pollution sources.

• Electronics, optics, LCD liquid crystal manufacturing, precision instruments, hospital operating rooms and other high cleanliness environment.

Use and Maintenance

• Pre-installation inspection: The exterior of the filter should be checked for damage before installation to ensure that there is no foreign matter blocking.

• Regular inspection: The differential pressure of the filter should be checked regularly during use to keep it within the specified range.

• Cleaning and Replacement: Clean or replace the filter at the right time according to the changes of the usage and pressure difference.

• Environmental control: Maintain suitable temperature and humidity to avoid the decline of filter performance caused by environmental factors.

Service life

The service life of the knife frame type high efficiency filter without partition is affected by many factors, such as the quality of filter material, air flow, sealing of the filter, the use environment and installation and maintenance, etc. In general, if the filter is used at the rated capacity, it will be used for a long time. Generally speaking, if used under rated air flow and suitable environment, its service life can be more than one year. However, if the front-end protection of the filter is insufficient or the use environment is poor, the service life may be shortened.

Design Features

• Filter Media Material: Made of ultra-fine glass fiber filter paper with thermoplastic separators to ensure filtration efficiency and stability.

• Structural design: The design of thermoplastic spacer without separator can ensure the same pleat layer spacing to ensure the optimal airflow through to achieve high dust holding capacity, while fully utilizing the filter media throughout the entire depth of the filter.

• Sealing performance: The filter is sealed all around with a special sealant to ensure that the entire filter is airtight and leakage problems are avoided.

• Protective measures: Plastic spraying protective net is installed on the inlet and outlet surfaces of the filter to effectively protect the filter paper from damage.

• Unique appearance: the air outlet surface of this filter comes with a certain length of knife edge, which increases the recognizability.

• Strict test: each filter has been strictly tested to ensure product quality.

• Filtration efficiency: It has H13 and H14 level filtration efficiency and meets EN1822 standard.
