1. OverviewAir filters are core components of ventilation and air purification systems. Their main function is to capture suspended particles in the air (such as dust, pollen, microorganisms, aerosols, etc.) through physical interception, adsorption and other methods, thereby improving indoor air qu

I. Efficiency Classification (Core Standard) Primary Efficiency Filters (GB/T 14295)Function: Intercept particles ≥5μm (such as dust, hair) for pre-filtration.Efficiency: 40%~90% by weight method (G1-G4 grades). Medium Efficiency Filters (GB/T 14295)Function: Capture particles of 1~5μm (such as poll

High-Efficiency Air FiltersDefinition & FunctionsAs the ultimate gatekeeper of filtration systems, high-efficiency air filters deliver the finest level of filtration. They are primarily designed to capture submicron-sized particles (diameter < 1μm), including smoke, viruses, radioactive aerosols, as

Air filters are generally classified into three main grades based on their filtration efficiency and particle capture capability: primary-efficiency filters, medium-efficiency filters and high-efficiency filters. They are often used in series in a system to form a filtration barrier ranging from coa

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 gu

1. Oil Filter Function: The oil filter cartridge is used to remove impurities, dirt, and metal particles from the engine oil, ensuring the oil remains clean. This protects the internal components of the engine and extends its service life.Replacement Interval: Typically replaced during an oil change
