Attention to those in the petroleum, chemical, and pharmaceutical industries: Choosing the wrong filter will cause a sharp increase in consumable and labor costs! How to select between candle-type and plate-type filters? We clarify their core differences for you.1. Structure: The difference lies in

Panel Filter DescriptionThe F7 medium-efficiency panel filter is suitable for intermediate filtration in ventilation systems, mainly used to filter submicron (＜1μm) dust particles and various suspended substances.Panel HEPA FilterStructureThe frame material can be aluminum alloy frame, galvanized fr

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

The adaptability of G4 class filters in industrial environments is mainly reflected in the following aspects:Filtration EfficiencyG4 class filterscan trap particles larger than 5 microns, which is sufficient to meet daily air filtration needs in many industrial environments.Resistance DesignPrimary

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

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

1.Class G (Primary Efficiency Filter)Filtration Efficiency: Mainly used to filter particles larger than 5μm. For example, the filtration efficiency of Class G4 is approximately 40%.Application Scenarios: Suitable for primary filtration in air conditioning systems, such as pre-filtration for central
