Anti-Vortex Suction Outlet
The effective deployment of fire sprinkler systems for homes and public spaces, like maraes and churches, depends on a clean and even water flow. The Anti-Vortex Suction Outlet from Promax makes this possible.
The anti-vortex suction outlet is commonly used on high-flow suction points to stop cavitation. Cavitation refers to the development of air bubbles in a liquid due to pressure changes. When this occurs, there’s an uneven “stop start, stop start” effect on the water used for fire fighting with the potential to damage the sprinkler equipment.
- Compliant to Automatic Fire Sprinkler Systems NZS 4541:2020
- Custom applications are available.
- Promax supply tanks for firefighting purposes, with a range of capacities depending on your requirements.
The Promax Anti-Vortex Suction Outlet prevents vortex air inclusion when the water is under suction. It is indispensable as a firefighting safety measure, and our industrial team will be happy to explain further how it works.
Please note: This product is available for factory fit only.

All standard Promax ENDURO and XPRESS large tanks are perfect for domestic fire hydrant storage. While 45,000 LTRs is the general minimum requirement for domestic hydrant storage, your local council may have specific requirements. Note for commercial hydrant storage, you may require additional industrial components for compliance. Check with our team if you are needing commercial hydrant storage. For pricing on domestic hydrant tanks, see our domestic water tank range.
Fire service kits are essential for connecting tanks to fire hoses. Fire service kits allow for easy access to tank water and ensure an even and high-pressure flow. The kit is the connection between a tank and a hose, and usually consists of a 100mm fire coupling adaptor, a fire coupling support, a brass gate valve, and a tank fitting. Any kit of this nature must be a Fire and Emergency New Zealand (FENZ) Approved Fire Coupling for compliance, functionality and safety. Promax Fire service kits vary according to how the tanks are set up at a particular property. For example, a standard fire kit will connect to one above ground tank. Meanwhile, if two above ground tanks are interconnected and water is drawn from both tanks at the same time, it is possible to buy a dual fire outlet kit; as two tanks are often required to reach the minimum capacity of 45,000 litres, a dual kit is a popular option.
Yes, you can use multiple tanks. Promax offers Dual Tank Fire Service Outlet Kits that allow you to interconnect and draw water from both tanks simultaneously.
