Product introduction: It consists of a cast shell and a filter medium in the middle.
Product advantages: simple structure, low cost, high reliability, simple operation, disposable use, replacement after use, no maintenance device.
Filter material: Electret is a dielectric material that can store space charge and dipole charge for a long time.
Filtration efficiency: Large particles larger than 1 micron mainly move in inertial motion. The larger the particles, the higher the filtration efficiency. Small particles smaller than 0.3 microns mainly move by diffusion. The smaller the particles, the higher the filtration efficiency. Medium particles between 0.3 and 1 micron. For small and large particles, the filtration efficiency through mechanical barrier alone has a lowest point. Combined with electrostatic adsorption, the filtration efficiency of the filter medium for small and medium-sized particles can be significantly improved.
