The VZN-441V and VZN-441V-T5 systems offer premium filtration so you can serve your customers the highest quality water at the lowest price. Water goes through self-cleaning ultra-filtration before it reaches the carbon cartridge to separate mechanical filtration from taste and odor reduction. This ensures longer carbon cartridge life and eliminates clogging. The VZN-441V-T5 also features Template Assisted Crystallization to remove lime-scale buildup on your equipment.
