Dual dilution option allows the user to simply turn a lever to create a different dilution rate for the same concentrate--perfect for light and heavy cleaning. State-of-the-art materials withstand harsh chemicals and the durable design and construction assure long-term performance. Turn water on and off right at the unit so users do not have to continuously go back and forth to a central mixing station. Ergonomically designed for safety and productivity with one-handed operation. Accurate dilution control can be built right into the portable unit, preventing any tampering with water to chemical ratios. Portable units are also much less expensive to purchase, install, and maintain than wall-mounted systems.
