Runxin F74A Automatic Softener – Smart & Automatic Water Treatment
The Runxin F74A automatic softener offers a high-performance and fully automatic solution for softening water in residential and RO pre-treatment systems. It intelligently manages regeneration cycles and delivers consistently softened water without requiring constant manual input.
Key Features of the Runxin F74A Automatic Softener
- Automatic Regeneration: The softener supports both time-based (clock) and metered regeneration modes, depending on the model.
- Reliable Sealing: It uses hermetic ceramic head faces known for high corrosion resistance and long-term durability.
- Multiple Regen Stages: It includes Service, Backwash, Brine & Slow Rinse, Brine Refill, and Fast Rinse cycles for efficient resin regeneration.
- Manual Regen Button: You can trigger regeneration whenever needed, offering flexibility during maintenance.
- Outage Memory: If power goes out for more than 3 days, the display flashes “12:12” to remind you to reset the clock, but your previous settings remain.
