Rain Bird MPR-15F spray nozzle - 360° full-circle - 3.4 to 4.6 m radius

Rain Bird MPR-15F spray nozzle for larger lawns

The Rain Bird MPR-15F is a fixed-pattern spray nozzle with a 360° full-circle spray pattern and a radius of 3.4 to 4.6 m. It is particularly suitable for automatic irrigation of larger lawns where a sprinkler is installed within the grass area. The nozzle distributes water in every direction around the sprinkler, providing circular coverage of the surrounding lawn.

As part of the Rain Bird MPR Series, the MPR-15F features matched precipitation rates that help coordinate water distribution across different spray patterns. It is a practical choice for centrally positioned sprinklers requiring complete circular coverage over a longer distance. Compared with the MPR-12F, it provides a greater maximum radius, provided the available water supply is sufficient.

360° full-circle coverage with up to 4.6 m radius

The fixed 360° spray pattern makes the Rain Bird MPR-15F particularly suitable for sprinkler positions within continuous lawn areas. Water is distributed around the entire sprinkler head. Typical applications include larger residential gardens, central lawn sections and grass areas with sufficient distance from paths, patios and other paved surfaces.

The spray radius ranges from 3.4 to 4.6 m depending on operating pressure. At the optimum pressure of 2.1 bar, the nozzle reaches approximately 4.6 m. Its spray trajectory is 30°. The integrated stainless steel adjustment screw allows the radius to be reduced when necessary. Rain Bird does not recommend reducing the normal spray radius by more than 25%.

Matched precipitation rates for balanced irrigation

MPR stands for Matched Precipitation Rate. Rain Bird MPR nozzles are designed with coordinated precipitation rates to simplify the combination of different spray patterns. With correct sprinkler placement, suitable quarter-circle, half-circle and full-circle nozzles can be combined to provide balanced irrigation across differently shaped lawn areas.

The Rain Bird MPR-15F has a flow rate of approximately 9.8 to 14.0 l/min depending on operating pressure. At 2.1 bar, the manufacturer performance chart lists a flow of 0.84 m³/h, equivalent to 840 litres per hour. This relatively high water requirement should be considered when planning an irrigation zone. Adequate supply capacity, suitable operating pressure and correct sprinkler spacing are essential.

Easy installation on Rain Bird spray bodies

The Rain Bird MPR-15F 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 protect the nozzle from debris. The stainless steel adjustment screw allows convenient radius adjustment during installation.

For automatic lawn irrigation, the MPR-15F can be combined with suitable MPR-15Q quarter-circle and MPR-15H half-circle nozzles. These models have comparable spray radii at the same operating pressure but different spray patterns and flow rates. Pressure-regulated spray bodies can help maintain suitable nozzle pressure when the supply pressure is higher than required.

Frequently asked questions about the Rain Bird MPR-15F

What is the spray radius of the Rain Bird MPR-15F?

The spray radius ranges from 3.4 to 4.6 m depending on operating pressure. At 2.1 bar, the nozzle reaches approximately 4.6 m.

Can the 360° spray angle be adjusted?

No. The MPR-15F has a fixed full-circle spray pattern. However, the radius can be reduced using the stainless steel adjustment screw.

How much water does the MPR-15F use?

The flow rate ranges from approximately 9.8 to 14.0 l/min. At 2.1 bar, the manufacturer lists 0.84 m³/h, equivalent to 840 litres per hour.

Which sprinkler bodies are compatible?

The Rain Bird MPR-15F 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-15F with other MPR nozzles?

Yes. It can be combined with suitable MPR-15Q quarter-circle and MPR-15H 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-15F and MPR-12F?

The MPR-15F reaches up to 4.6 m, while the MPR-12F reaches up to 3.7 m. Both have a fixed 360° spray pattern and a 30° spray trajectory.
