Streamline commercial housekeeping, janitorial sanitation, and facility maintenance with this authentic DEMA 681-3 Blend Center Chemical Proportioning Dispenser. Built around a durable stainless steel chassis with dedicated station push buttons, this heavy-duty 3-station liquid dilution control unit is engineered to accurately mix and dispense up to three chemical concentrates into spray bottles, mop buckets, or automatic scrubbers. Features easy-access internal valve assemblies for toolless servicing and reliable proportioning flow rates. Offered as the dispenser unit only—ideal as a replacement system or modular addition to commercial chemical setups.
