Structure and Materials: The plate air filter adopts a unique plate structure, and the filtering material is usually composed of synthetic glass fibers. This material has the characteristics of large dust capacity and long service life, and is mostly used for primary air filtration.

Working principle: The plate air filter mainly intercepts and adsorbs particulate impurities in the air through a filter screen to provide clean air. Among them, inertial action and electrostatic action are the two main filtering mechanisms. When dust particles in the air collide with the plate filter, they will be intercepted due to the inertia of the particles. At the same time, some plate type high-efficiency air filters adopt electrostatic dust removal technology. When the dusty gas passes through a high-voltage electric field, ionization occurs, causing the dust particles to be positively charged and move towards the anode surface under the action of the electric field force, thus being adsorbed.

Application scenarios: Plate air filters are widely used in various fields, including industrial production sites (such as factory workshops, manufacturing workshops, etc.), commercial and office environments (such as office buildings, shopping malls, hotels, etc.), and air conditioning systems. In industrial production sites, plate air filters are mainly used to filter dust, particulate matter, and harmful gases in the air, to ensure the health of workers and the normal operation of production equipment. In commercial and office environments, plate air filters are used to purify indoor air and improve indoor air quality.

Advantages and disadvantages: Plate air filters have the characteristics of long service life, low resistance, high breathability, and low flammability, which can reduce maintenance and usage costs. At the same time, its filtration effect is good, it does not produce secondary pollution, and is environmentally friendly. However, plate air filters also have some drawbacks, such as high initial resistance, the need for large air volume to function properly, which increases equipment costs and energy consumption. In addition, some high-efficiency filters use filter materials such as electrostatic textiles, which have certain flammability and are not suitable for use in flammable and explosive situations. In addition, high-efficiency filters are generally non washable and non reusable, requiring regular replacement, which increases the cost of use.
