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. 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

Stainless Steel Bag Filter Core Data:Filter precision: 1–200 μm (commonly 5–100 μm).Operating temperature: -200°C to +550°C (material-dependent).Pressure resistance: ≤1.0 MPa (depending on frame structure).Pore size: 15–50% (affects flux and pressure drop).Thickness: 0.1–1.0 mmAir permeability: 100–

A stainless steel mesh filter bag is a precision filter element woven from metal wire. It is made of stainless steel materials such as 304, 316 and 316L, and made by multi-layer weaving or sintering process. It is used for solid/liquid/gas separation in high temperature and corrosive environments.St

The significance of the filtration stage in the industrial production process is self-evident. The stainless steel mesh filter bag we are going to introduce today is a professional product, developed specifically for industrial filtration needs. As a key component of the filtration system, this prod

Bag Air Filter is the most common "medium-efficiency" or "sub-high-efficiency" stage filter for central air conditioners, air handling units (AHUs), cleanroom air conditioners, constant temperature and humidity systems, and desiccant rotors. Gezi Filtech Manufacturing Co., Ltd. has extensive applica

A filter bag is a filter element that allows the liquid in the suspension or the gas in the gas flow, containing solid particles, to pass through under the action of an external force, and intercepts the solid particles, so as to achieve the separation of solid particles from the liquid or gas. It i

Filter bags come in various types based on their filtering medium.1.Liquid filtration bag filter purify liquids like water, oil, and chemicals. They cover a wide filtration range (1–300 μm) to meet cleanliness standards.2.Gas filter bags, also known as dust removal filter bags, purify flue gas and d

PE filter bags are industrial filtration components made from polyethylene (PE). They utilise needle-punched non-woven fabric technology to create a three-dimensional filter layer, featuring loose fibres and high contaminant capacity.The double flow mode is adopted, the large particles are retained
