The Atlas Filtri DOSAFOS PLUS – 10" Senior model is a non-proportional dosing system designed for technical and industrial water applications where prevention of limescale and corrosion is critical. It doses food-grade polyphosphate crystals directly into the water line to protect pipelines, boilers, and equipment from scaling without requiring electricity or pumps.

The system features a reinforced polypropylene head and energy-efficient PET bowl that is 100% recyclable, making it both reliable and environmentally friendly. Certified under stringent international standards, the DOSAFOS PLUS is suitable for treated or technical water applications.

  • Non-proportional dosing – releases fixed amount of polyphosphate crystals.
  • Durable and certified materials for long-term reliability.
  • Eco-friendly design – recyclable PET body and low-energy manufacturing.
  • Quick and simple installation with BSP threaded connections.
