Features and Benefits
Helicoidal microbubble separation
The helicoidal microbubble separation combines and expands the main known separation principles into an unrivalled overall concept. By reducing the flow, large bubbles are channelled directly upwards into the quiet zone to the deaerator. Microbubbles, on the other hand, adhere to the spirally arranged vanes, combine there to form larger bubbles and, after detaching from the vanes, can rise upwards to the deaerator in a central column with little turbulence.
Safe, durable and reliable venting
The automatic air vent ensures safe and dry discharge of the separated gas bubbles into the environment. The special arrangement and design of the air vent allows the float to work stably in a large, flow-calmed chamber. This keeps dirt and water away from the precision vent valve, even at high pressures.
