Antelco Rotor Max butterfly sprinklers for greenhouses, vegetable beds and under-tree watering. Water turns a spinner with two outlets, spraying upwards and around the head in a full circle. The 25° spray rises above the sprinkler before falling onto the surrounding plants.
Each sprinkler is supplied with the colour-coded nozzle for that model. The nozzle opening controls water flow, while water pressure also affects flow and coverage.
Mount upright on a suitable riser with a matching female BSP connection. Position the head so nearby leaves and stems do not block the spray. Allow for overlapping coverage when planning sprinkler spacing.
Nozzle comparison
At 200 kPa, the green nozzle uses the least water and covers a smaller area. The red and black nozzles both reach a 13m wetted diameter at this pressure, but the black nozzle delivers more water. The purple nozzle has the highest flow and reaches a 13.8m diameter.
| Supplied Nozzle | Flow at 200 kPa | Wetted Diameter at 200 kPa |
|---|---|---|
| 2.4mm green | 315L/h | 10m |
| 2.8mm red | 400L/h | 13m |
| 3.2mm black | 540L/h | 13m |
| 3.8mm purple | 775L/h | 13.8m |
Across 100–300 kPa, the four stocked nozzles cover 7.6–14m wetted diameters and use 215–975L/h. Use the figures for the selected nozzle and pressure when planning the system.
Performance figures are for upright 25° sprinklers on a 200mm riser. Wetted diameter is the width of the watered circle, not the distance between sprinklers.
The UV stabilised polypropylene frame and acetal spinner and nozzle suit outdoor use. The sprinkler can be taken apart for inspection and cleaning.
