air filter / bag / cartridge / pleated

MultiPuls-WT depth filter cartridges are employed instead of pulse filters (surface filters) wherever the dust concentration is lower than 0.2 mg/m³, or when relative humidity is very high and the use of retention filters (depth filters) is advisable.

The basic design of MultiPuls-WT depth filter cartridges corresponds to that of MultiPuls-W pulse filter cardridges, but the depth filters feature special fiber-glass materials as filter medium. As protection, prefilter bag cartridges made of special synthetic fleece are used. Depth filter cartridges have a star-shaped, pleated filer medium. They are used with moderate dust loads and small particle sizes for optimal cleaning of the intake air for gas turbines, compressors, and motors.
