Runxin F77A Automatic Softener — Efficient & Smart Water Softening
The Runxin F77A automatic softener offers precise, fully automatic water softening for homes, offices, and RO pre-treatment systems. It actively monitors water flow and regenerates the resin when needed, ensuring soft, clean water without manual intervention
Key Features

- Durable Dual-Core Design: One core handles inflow and brine, while the other manages outflow and drainage, providing reliable performance.
- User-Friendly LED Display: The screen clearly shows whether the valve is in service or regenerating, making operation simple.
- Manual Regeneration Option: You can initiate regeneration anytime using the built-in button, which offers flexibility during maintenance or high water demand.
- Robust Construction: The ceramic head faces resist corrosion, extending the valve’s lifespan and reducing maintenance.
- High Flow Rate: The valve supports up to 18,000 L/h, which accommodates both residential and small commercial applications.
