Rain Bird MPR-8F spray nozzle - 360° full-circle - 1.7 to 2.4 m radius

Rain Bird MPR-8F spray nozzle for small lawns

The Rain Bird MPR-8F is a fixed-pattern spray nozzle with a 360° full-circle spray pattern and a radius of 1.7 to 2.4 m. It is particularly suitable for automatic irrigation of small to medium-sized lawns, compact landscaped areas and centrally positioned sprinklers. Its circular spray pattern distributes water around the entire sprinkler head, making it useful for lawn areas that require coverage in every direction.

The MPR-8F belongs to the Rain Bird MPR Series, which features matched precipitation rates for coordinated water distribution. It provides targeted irrigation for compact lawn areas and can be combined with suitable quarter-circle and half-circle nozzles from the same series to accommodate different lawn shapes.

360° full-circle coverage with up to 2.4 m radius

The fixed 360° spray pattern allows the Rain Bird MPR-8F to distribute water evenly in all directions. It is particularly useful for sprinkler positions within a lawn, small grass islands and compact landscaped spaces requiring complete circular coverage. Quarter-circle or half-circle nozzles are generally better suited to lawn corners and edges.

The spray radius ranges from 1.7 to 2.4 m depending on operating pressure. At the optimum pressure of 2.1 bar, the nozzle reaches approximately 2.4 m. Its spray trajectory is 10°. An integrated stainless steel adjustment screw allows the radius to be reduced when required.

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-8F has a flow rate of approximately 2.8 to 4.0 l/min depending on operating pressure. At 2.1 bar, this corresponds to about 240 litres per hour. Since the full-circle nozzle covers a larger area than the corresponding quarter-circle and half-circle models, it requires a higher flow rate. This should be considered when planning the irrigation zone.

Easy installation on Rain Bird spray bodies

The Rain Bird MPR-8F fits compatible Rain Bird spray bodies and suitable shrub adapters, including models from the Rain Bird 1800 Series. A blue fine-mesh filter screen helps prevent debris from entering the nozzle. The stainless steel adjustment screw allows convenient radius adjustment during installation.

For automatic lawn irrigation, the MPR-8F can be combined with suitable MPR-8Q quarter-circle and MPR-8H half-circle nozzles. These models have comparable spray radii at the same operating pressure but different spray patterns and flow rates. Ensure that adjacent sprinklers overlap sufficiently and that the water supply provides adequate pressure and flow. Pressure-regulated spray bodies can help maintain consistent nozzle pressure when supply pressure is higher than required.

Frequently asked questions about the Rain Bird MPR-8F

What is the spray radius of the Rain Bird MPR-8F?

The spray radius ranges from 1.7 to 2.4 m depending on operating pressure. At 2.1 bar, the nozzle reaches approximately 2.4 m.

Can the 360° spray angle be adjusted?

No. The MPR-8F has a fixed full-circle spray pattern. However, the radius can be reduced using the integrated stainless steel adjustment screw.

How much water does the MPR-8F use?

The flow rate ranges from 2.8 to 4.0 l/min, equivalent to approximately 168 to 240 litres per hour.

What does MPR mean?

MPR stands for Matched Precipitation Rate. These nozzles are designed to provide coordinated precipitation rates across different spray patterns in a correctly planned irrigation system.

Which sprinkler bodies are compatible?

The Rain Bird MPR-8F fits compatible Rain Bird spray bodies and shrub adapters, including models from the Rain Bird 1800 Series.

Can I combine the MPR-8F with other MPR nozzles?

Yes. It can be combined with suitable MPR-8Q quarter-circle and MPR-8H half-circle nozzles. Their different flow rates and the required sprinkler spacing should be considered during system design.
