Electrostatic Air Filter | Metal Panel Demister Filter

Saifilter Electrostatic Air Filter is also called Mesh Grease Filters or Washable filters. The Filter Medium is a knitted mesh interlocked with metal monofilaments. The media is enclosed in a galvanized steel or stainless steel frame. This Demister Filter is installed with fixed mesh on both sides, made from the same durable materials. Metal Panel Filter is installed on both sides with galvanized steel or stainless steel fixed mesh. Mesh Grease Filters are reusable, and the regeneration process involves high-pressure jet cleaning using compressed air or water-containing detergent. High free volume (97% to 99+% void content) and uniform wire mesh density distribution. Captures smaller diameter droplets more efficiently.

Because the filter layer adopts a multi-layer superimposed structure, it forms an efficient filter barrier. Air Filter Panel Metal can capture liquid droplets and solid particles in gas liquids while allowing clean air particles to move through the Filter Material. And maintain a low initial pressure drop. Depending on application requirements, additional handles can be added to the metal plate to facilitate removal and cleaning. Drainage holes can also be added to the bottom of the frame to drain grease from the Extractor Fan Mesh Filter into the grease trap.

A Metal Panel Demister Filter is used in industrial processes to remove liquid droplets from gas streams. It typically comprises a mesh or pad made from metal wires or fibers. As the gas passes through this mesh, the liquid droplets collide with the metal, merge, and fall away, thus purifying the gas stream.

They offer high efficiency in separating liquid from gas, durability, and resistance to corrosion. Their design allows for minimal pressure drop across the filter, maintaining the efficiency of the system in which they are installed.

Installation involves placing the filter in the appropriate position within the system, considering factors like size and orientation. Maintenance typically includes regular inspection, cleaning, and replacement of components as needed to ensure optimal performance.

Environmental factors like temperature, humidity, and the presence of corrosive elements can impact the filter's efficiency. Materials and design can be adapted to withstand these conditions and maintain performance.

Key considerations include the type of gas and liquid being separated, the operating conditions (like temperature and pressure), the desired efficiency, and the specific environmental conditions of the industrial process. These factors determine the material, design, and size of the filter needed
