The Function And Classification of Air Filtration

I. Air filter:

1. Air filtration function:

The air filter assembly is an integral component for air intake filtration. Its main function is to filter impurities in the air (such as dust, etc.) through the air filter element inside, ensuring that the gas entering the air compressor is clean, thereby guaranteeing the normal and stable operation of the air compressor.

2. Classification:

1) Classified by filter material: paper filter elements and fibre filter elements.

2) Classified by structure: single-stage air filters and multi-stage air filters.

Different types are suitable for different working environments and compressor requirements:

1) Material selection: High-quality filter materials are adopted, capable of blocking over 95.5% of dust, and the filtration rate for particles smaller than 5 microns reaches 99%.

2) Structural design: The wavy, laminated design increases the filtration area and enhances the filtration effect.

3) Sealing performance: After the air filter cartridge is installed in the housing, it undergoes sealing treatment to ensure that air only enters the machine through the filter material.

4) Performance indicators:

Filtration effect: The dust filtration rate reaches 5%, equivalent to the level of N95 masks. The filtration rate for particles larger than 5 microns reaches 99%.

Sealing performance: The gap is less than 1 millimetre, preventing dirty air from entering.

Strength: The casing can withstand 5 times the working pressure without deformation. The tear strength of the filter paper is greater than 100 Newtons per meter.

Service life: The replacement cycle is 4,000 hours under normal conditions. In harsh environments, it needs to be shortened to over 2,000 hours.

Environmental protection standard: The filter material is recyclable.

Safety: Equipped with anti-static design, the static resistance of metal parts is less than 10 Ω, preventing the generation of electric sparks.

The air filter assembly is a front-end filtration system, which directly affects the wear degree of internal parts of the main unit, the operating efficiency, and service life of the machine.
