The Anthracite Azure 370 is a high-capacity, low-maintenance water softener designed for efficiency and long-term performance. With up-flow proportional brining, it ensures optimal salt consumption and water savings while delivering a high flow rate of up to 2.9 m³ per hour. A large salt capacity of 130 kg allows for up to 15 months of operation before requiring a refill.
