Dust filters are used for dedusting of various-size silos loaded pneumatically with dusty materials. Depending on the kind of stored material, various filtering liners are used, as well as various methods of the filter regeneration (mechanical, pneumatic). The whole filter case is made of acid-resistant steel. Depending on the requirements, a filter may be equipped with a fan for sucking dusty air from the loader. The filter size is adjusted to the planned volume of air to be dedusted.
