SPECIAL FILTER® is a compact cartridge platform combining activated-carbon filtration with FILTERSORB® SP3 scale-prevention media. The SP 520UF model adds an ultrafiltration membrane.
The activated-carbon block supports the reduction of chlorine, unwanted taste, odor and sediment, while FILTERSORB® SP3 helps reduce the formation of hard scale without adding sodium or phosphate. The SP 520UF incorporates a nominal 0.1-micron ultrafiltration stage for additional fine-particle and microbiological control when operated within validated conditions. The quick-change head includes automatic water shut-off for faster, cleaner cartridge replacement.
SPECIAL FILTER® cartridges are designed for cold-water, point-of-use installations where improved taste, sediment reduction and scale protection are required.
Compact filtration for improved taste, odor and clarity at the point of use.
Scale protection and chlorine reduction for beverage equipment and coffee preparation.
Treated water for beverage preparation and compatible catering equipment.
Filtration for connected cold-water appliances and ice-production systems.
Compact cartridge treatment for water-fed beverage-vending equipment.
Scale-management support for compatible appliances operating within temperature and flow limits.
The carbon-block stage supports chlorine, taste, odor, sediment and selected adsorbable-organic reduction when supported by appropriate performance testing.
FILTERSORB® SP3 supports nucleation-assisted crystallization, helping convert dissolved temporary-hardness minerals into microscopic crystals with a reduced tendency to attach to equipment surfaces.
Available in the SP 520UF model, the ultrafiltration membrane provides an additional barrier for fine particles and microorganisms larger than the validated membrane cutoff.
The insert-turn-lock cartridge connection and automatic water shut-off simplify cartridge replacement without regeneration, electricity or a separate brine system.
