The wire mesh type shielding ventilating board is mainly composed of the pleat, multilayer of aluminium mesh and filter screen (if necessary). Besides the high shielding property, it also realizes the minimum wind resistance and excellent dust control effect. The wire mesh is made with 7 layers of aluminum foil through special processing. The multilayer aluminum foil can not only filter the dust flow in the air, but also speed up the cooling of the air passing through it. This product can be cleaned by soaking and stirring it in a container with appropriate solvent, and its performance won't be affected. It's applicable to chassis, large housing, the area with a high wind speed, and the equipment in a limited space. The wire mesh thickness (7 layers of aluminum foil) is about 2.4mm; two layers of wire mesh (14 layers of aluminum foil) can be superposed to reach better shielding effectiveness. With the aluminium profile framework, its thickness can reach 6.5mm - 12.7mm, and its plan vie
