- Main Irrigation Networks – Air relief, protection against air accumulation and vacuum formation downstream of pumps, along supply lines and at elevations in main irrigation networks.
- Irrigation Control Heads – Air relief, protection against air accumulation and vacuum formation at filtration and fertilization stations and downstream of main control valves. Infield Systems – Protection against air accumulation and vacuum formation in proximity to water meters and automatic regulators.
- Landscape Irrigation – Protection against air accumulation and vacuum formation.
- Pumping stations - Maximising pumping efficiency, priming capabilities and reducing the possibility of pressure surges during power failure modes.
