Cartucho de filtro soplado Matte Melt

What sets the matte cartridge apart is its outer layer — a specially treated PP cotton thread surface that intercepts particles before they penetrate the inner filtration structure. Inside, dense polypropylene microfibers are thermally entangled into a gradient density core with loose outer layers and a dense inner core. This dual mechanism of surface interception combined with depth filtration prevents surface clogging, greatly improves dirt holding capacity, and extends service life beyond what standard smooth-surface cartridges can achieve. Available in all standard filtration ratings from 1µm to 60µm — see Pullner’s full melt blown filter cartridges lineup for other surface options.

Aplicaciones

The matte cartridge’s anti-clogging design makes it particularly effective in applications where surface blockage is a common issue:

Industrial Water: Pre-filtration of process water with moderate to high particulate loads
Tratamiento del agua: RO membrane pre-filtration, municipal water, industrial wastewater
Comida y bebida: Filtration of drinking water, alcohol, and beverages
Pharmaceutical: Pre-filtration of injections, liquid medicines, and antibiotics
Petróleo y química: Organic solvents, acids, alkalis, oilfield water injection
