Precision Engineering & Durability

• Heavy-Duty Brass Construction: Cast from high-copper, low-zinc brass to ensure maximum resistance to dezincification and long-term structural integrity in demanding environments.
• Superior Piston Mechanism: Features a high-performance, slow-closing piston flushing mechanism that maintains consistent cycle times and accurate flush volumes regardless of water pressure fluctuations.
• Chemical-Resistant Seals: Equipped with industrial-grade VSI silicone elastomer piston seals, specifically formulated to withstand the harsh effects of chlorine, chloramines, and ammonia.
• Integrated Debris Protection: Includes a standard self-cleaning filtering system that protects the internal solenoid and piston from waterborne sediment and mineral buildup, extending the life of the unit.

Advanced Operational Intelligence

• Battery-Powered Independence: Powered by four (4) standard AA alkaline batteries, providing a seamless touchless solution for retrofits or installations where hardwiring is not preferred. Includes an integrated low-battery indicator.
• Touchless ADA Compliance: The advanced infrared sensor provides a sanitary, "no-hands" experience, significantly reducing cross-contamination and meeting all ADA accessibility requirements.
• Smart Self-Diagnostics: Features an integrated electronic system with self-diagnostics and a manual reset function to simplify maintenance and troubleshooting for facility managers.
• Automatic Hygiene Flush (Sentinel Flush): Includes a built-in 36-hour sentinel flush feature to automatically activate the valve during periods of inactivity, maintaining the trap seal.
• True Mechanical Override: Equipped with a standard manual-mechanical override button, ensuring the toilet remains fully functional even in the event of battery failure.
