The service life of high temperature dust bag is generally one year warranty. The premise is that conditions, materials, and use are correct. First of all, it is critical to choose the quality of the high-temperature dust bag, and no open lines, cracks, falling bottoms, etc. can occur. In addition, the use temperature of the high-temperature dust bag must be selected. In order to save costs, some manufacturers use low-temperature or medium-temperature high-temperature dust bags instead of high-temperature dust collector bags to speed up the use of high temperature dust bags. Life expectancy caused burns in a short time. Therefore, when selecting the filter bag, it must be determined to calculate the inlet temperature of the filter, and use the corresponding high temperature dust bag. In this way, the high-temperature dust bag can be used for a longer period of time and cannot be a temporary price. Cause unnecessary losses. Each working condition has a corresponding high-temperature dust bag material, which is integrated with the dust removal equipment to achieve the best use effect, reduce costs, and create better economic benefits.
