Product Overview

The BAC901A02 belongs to the premium BAC901 Series Automatic Backflushing Controllers. It serves as an intelligent automatic backflushing control system composed of a built-in computer controller, internal differential pressure (DP) sensor, and flexible programming software. By commanding solenoids, three-way backflushing valves, and hydraulic valves, it triggers efficient backwash cycles sequentially to ensure continuous, uninterrupted clean water supply.

Key Features & Advantages

  • Smart Multi-Trigger Modes: Rinsing cycles can be fully automated and triggered by Pressure Differential (DP) only, Time intervals only, or via Manual Flushing overrides.
  • Integrated DP Sensor: Features a built-in DP sensor with convenient calibration features (zero-point calibration without disconnecting ports).
  • Modular & Scalable Design: The modular structure design can be easily configured and adapted from 1 up to 10 filter units based on user requirements.
  • Heavy-Duty Outdoor Protection: Engineered with a robust modular structure design and IP65 waterproof rating to withstand harsh environmental conditions.
  • Real-Time LCD Monitoring: The clear LCD field screen provides live data tracking, including actual pressure differential values, current backflushing station numbers, and time remaining until the next cycle.
  • Safety Alarms: Safeguarded with advanced alarm features, including low battery power alerts (for DC models) and continuous endless looping backflushing system buzzer alarms.
