Maelstrom Vortex Rain Head Range

The Maelstrom range represents the pinnacle of rain head technology. Using a vortex action, these units create a centrifugal force that separates debris from water, keeping the screen clean while maximising flow rates. This innovative design means the Maelstrom requires significantly less maintenance than conventional rain heads, making it ideal for installations where access is difficult.

Particularly suited to UK properties with large roof areas where high volumes of water need to be handled during heavy rainfall events, the Maelstrom range is manufactured from UV-stabilised materials suitable for the British climate. The vortex design ensures that even during intense downpours, water flows freely into your tank without the bypass that can occur with standard screens.

The Maelstrom range is available in several sizes to match different downpipe diameters and roof areas. Installation is straightforward, with the unit fitting directly onto standard UK downpipes. The transparent lid allows for visual inspection without disassembly, and the collection basket is easily emptied during routine maintenance.

For commercial applications and large residential properties, the Maelstrom offers the highest flow rates in our product range. It is the recommended choice for systems where roof area exceeds 200 square metres or where gutters are prone to accumulating debris from overhanging trees.

The Maelstrom works as part of a complete system alongside tank screens, first flush diverters, and sediment management components. For properties using standard rain heads, explore our standard rain head range for a more traditional solution.

Why Choose Vortex Technology?

Vortex filtration is particularly effective in the UK climate, where autumn leaf fall and winter storms can overwhelm standard filters. The self-cleaning action means your rainwater harvesting system continues to perform at peak efficiency regardless of weather conditions, giving you peace of mind that every drop of rain is being captured.
