HS40AFC Compact – Compact continuous water level bubbler system
Compact continuous water level bubbler system
  • Continuous bubbler: constant pressure keeps water out of the river line – no contamination or clogging, no freezing
  • Low power consumption through modern electronics and optimized pump control
  • Desiccant and maintenance free
  • No need for gas bottles
  • Mechanical air drying allows use even in humid (e.g. tropical) conditions.
  • Maximum head (40 m) with 200m of river line (gauge house to orifice)
  • Robust construction of electromechanical components in industrial quality ensures many years of trouble-free operation
  • Selection of accessories: orifices in standard size (e.g. BU07) or large volume (e.g. GCO1P/SS)
