What are the filter materials for industrial vacuum cleaners
Industrial vacuum cleaners mainly separate solids and air through filter media. The filtration accuracy of filter materials is different, but don't think that the higher the filtration accuracy, the better the filtration accuracy, the higher the density of the filter material, the higher the resistance, and the greater the equipment suction force. Will decrease. If cleaning common industrial vacuum cleaners on the market generally have one or two filtrations, such as single-use filter element type for wet and dry type, dry type industrial vacuum cleaner uses dual filter system of filter element and filter bag, general filtration of filter element The precision is about 10 microns. The precision can be less than 1 micron by coating or using special materials. The filter fabric often uses non-woven fabrics or polyester needle felts. The precision can be maintained at about 0.5 microns through different manufacturing processes. At present, some companies have improved the filtration accuracy and greatly improved the degree of air purification by reforming and increasing the number of filter media. Generally, two or more filtration methods are commonly used, three-stage filtration is used for dry powder, and wet-dry type is used. Double filtration, welding smoke-dedicated vacuum cleaner adopts four-fold filtration method. Through the modification and upgrade of filter media, such as the use of high-efficiency filters (HEPA), the use of industrial vacuum cleaners can be expanded and the use effect can be improved.
The above is a detailed introduction to the filter materials of industrial vacuum cleaners. I hope that it will be helpful to you after reading. If you have any other questions and want to consult, you can contact us.
