General description

Combined filter material (SMS-Sbanbond-Meltblown-Sbanbond or SMCS-Sbanbond-Meltblown-Composite-Sbanbond) is used for the manufacture of pocket filters of different purification classes M5-F9 and is made in the form of a sleeve consisting of three/four layers of materials: outer layer - colored spunbond that regulates the cleaning class of the material / meltblown middle layer electrostatically charged bulk material based on ultra-thin polypropylene fibers / colorless spunbond or polyester pre-filter (composite) inner layer to trap large particles (allows to increase dust capacity and extend the life of the entire filter).

The combined SMS filter material has longitudinal separators as separators, which prevent sticking to adjacent pockets during operation. The longitudinal and transverse seams of the filter material are soldered using ultrasonic welding, using modern equipment.

Each batch of filter material is mandatory tested on the tester ALF 114 (TOPAS, GmbH), in accordance with GOST R EN 779-2014
