Conversion of bag filters and electrostatic precipitators into hybrid filters using bags of corrugated needle-punched fabric

The use of 3DESA filter cartridges with bags made of corrugated needle-punched fabric according to the technology of OOO DESA makes it possible to upgrade bag filters without changes in their design. Such modernization allows to increase the filtration area with unchanged number of bags and gas flow rate, reduce gas load and gas velocity between the bags, as well as significantly increase the inter-pulse interval.
