Foam soap dispenser features durable plastic components and is rigorously tested for high-usage environments to provide assurance of quality and long-term cost-efficiency. In case of vandalism or accidental damage, spare parts can be provided allowing repairs without having to take the dispenser off the wall. Dispenser push buttons are exclusively protected by BioCote, a silver-based antimicrobial agent that is incorporated into the plastic components at the time of manufacture and inhibits the growth of a broad spectrum of bacteria and molds. BioCote will not wear out or rub off and is effective for the lifetime of the dispenser. Fixed product dose delivers the exact amount required to control usage and waste. Ultrasonically sealed cartridge and pump mechanisms prevent the ingress of air into the cartridge during use to help prevent product contamination and ensure fresh product is dispensed every time.
