- Siphon water inlet
- Compact equipment
- Extractable model from TN
- Economic equipment

Design
- Stainless steel vortex with a minimum quality of 304 L on support plate made of very thick PEHD
- Nominal diameter from 40 to 180 mm
Operation
Tangentially supplying a circular chamber creates, through the increase in upstream pressure, a vortex current with the formation of an air core at the centre of it. The simple effect of the current allows for the limitation. The vortex effect limiter behaves as a hydraulic resistance and makes it possible to increase the reliability of the limiting system by a large passage section that is always constant.
