The Anthracite Azure 250 is designed for high efficiency, low salt consumption, and easy maintenance. With up-flow proportional brining, it delivers a high flow rate of up to 3 m³ per hour and offers a large salt capacity, ensuring long-term operation with minimal intervention. A full tank of salt lasts up to 15 months before requiring a refill, making it a cost-effective and convenient solution for water softening.

Key Features
✔ Reliable Clack® DV Valve – US-made with diamond-carbon coating for durability and optimal performance.
✔ Increased Salt Capacity – Holds up to 130 kg of salt for extended operation.
✔ Built-in Mixing Valve – Allows for precise control of water softness.
✔ Up-Flow Proportional Regeneration – Ensures smart salt and water consumption for efficiency.
✔ Water-Saving Technology – Uses only 100 liters per regeneration cycle.
