6、Drying method of filter element

Put the filter element in 55 ℃ ~ 60 electric blast drying oven for 24 hours to ensure that the filter element is completely dry. Otherwise, it is necessary to extend the drying time until the filter element is fully dried. If the quality change of filter element is less than 1% in 1 hour before and after drying, it can be considered that the drying of filter element is completed.
