Rain Bird MPR-12F spray nozzle - 360° full-circle - 2.7 to 3.7 m radius

Rain Bird MPR-12F spray nozzle for lawn irrigation

The Rain Bird MPR-12F is a fixed-pattern spray nozzle with a 360° full-circle spray pattern and a radius of 2.7 to 3.7 m. It is designed for automatic lawn irrigation where a sprinkler is installed within the grass area. The nozzle distributes water in every direction around the sprinkler, making it suitable for circular coverage of surrounding lawn areas.

As part of the Rain Bird MPR Series, the MPR-12F features matched precipitation rates that help coordinate water distribution across different nozzle patterns. It is a practical choice for centrally positioned sprinklers requiring complete circular coverage. Compared with the MPR-10F, it provides a longer spray radius and can therefore be useful where sprinklers are positioned farther apart.

360° full-circle coverage with up to 3.7 m radius

The fixed 360° spray pattern allows the Rain Bird MPR-12F to distribute water over a circular area. It is especially suitable for sprinklers installed within continuous lawns rather than directly along their boundaries. Typical applications include central sprinkler positions in residential gardens, larger lawn islands and grass areas with sufficient distance from paths and patios.

The spray radius ranges from 2.7 to 3.7 m depending on operating pressure. At the optimum pressure of 2.1 bar, the nozzle reaches approximately 3.7 m. Its 30° spray trajectory supports water distribution over this distance. The integrated stainless steel adjustment screw allows the radius to be reduced, while the full-circle spray angle remains fixed.

Matched precipitation rates for balanced irrigation

MPR stands for Matched Precipitation Rate. Rain Bird MPR nozzles are designed with coordinated precipitation rates across different spray patterns. This makes it easier to combine suitable quarter-circle, half-circle and full-circle nozzles in a properly designed irrigation system while maintaining balanced water application.

The Rain Bird MPR-12F has a flow rate of approximately 6.8 to 9.8 l/min depending on operating pressure. At 2.1 bar, the metric manufacturer performance chart lists a flow of 0.60 m³/h, equivalent to 600 litres per hour. Consider this water requirement when planning your irrigation zone. Adequate supply capacity and suitable operating pressure are especially important when using several full-circle nozzles.

Easy installation on Rain Bird spray bodies

The Rain Bird MPR-12F fits compatible Rain Bird spray bodies and suitable shrub adapters, including models from the Rain Bird 1800 Series. A white fine-mesh filter screen is supplied to help prevent debris from entering the nozzle. The stainless steel adjustment screw allows convenient radius adjustment during installation.

For automatic lawn irrigation, the MPR-12F can be combined with suitable MPR-12Q quarter-circle and MPR-12H half-circle nozzles. These models have comparable spray radii at the same operating pressure but different spray patterns and flow rates. Correct sprinkler spacing and sufficient spray overlap are important. Pressure-regulated spray bodies can help maintain suitable nozzle pressure when supply pressure is higher than required.

Frequently asked questions about the Rain Bird MPR-12F

What is the spray radius of the Rain Bird MPR-12F?

The spray radius ranges from 2.7 to 3.7 m depending on operating pressure. At 2.1 bar, the nozzle reaches approximately 3.7 m.

Can the 360° spray angle be adjusted?

No. The MPR-12F has a fixed full-circle spray pattern. Only the radius can be reduced using the stainless steel adjustment screw.

How much water does the MPR-12F use?

The flow rate ranges from approximately 6.8 to 9.8 l/min. At 2.1 bar, the manufacturer lists 0.60 m³/h, equivalent to 600 litres per hour.

Which sprinkler bodies are compatible?

The Rain Bird MPR-12F fits compatible Rain Bird spray bodies and shrub adapters, including models from the Rain Bird 1800 Series.

What does MPR mean?

MPR stands for Matched Precipitation Rate. These nozzles are designed with coordinated precipitation rates to support balanced water distribution across different spray patterns.

Can I combine the MPR-12F with other MPR nozzles?

Yes. It can be combined with suitable MPR-12Q quarter-circle and MPR-12H half-circle nozzles. Their different flow rates and the required sprinkler spacing should be considered during system design.

What is the difference between the MPR-12F and MPR-10F?

The MPR-12F reaches up to 3.7 m and has a 30° spray trajectory. The MPR-10F reaches up to 3.1 m and has a 15° spray trajectory.
