Rain Bird MPR-10H spray nozzle - 180° half-circle - 2.1 to 3.1 m radius

Rain Bird MPR-10H spray nozzle for straight lawn edges

The Rain Bird MPR-10H is a fixed-pattern spray nozzle with a 180° half-circle spray pattern and a radius of 2.1 to 3.1 m. It is particularly suitable for automatic irrigation of lawns along straight boundaries. Whether next to a patio, garden path or wall, its half-circle spray pattern directs water towards the lawn on one side of the sprinkler.

The MPR-10H belongs to the Rain Bird MPR Series, which features matched precipitation rates for coordinated water distribution. It is a practical choice when the MPR-8H does not provide enough coverage and you still need a fixed half-circle spray nozzle. It is suitable for both new irrigation systems and replacement of existing spray nozzles.

180° half-circle coverage with up to 3.1 m radius

The fixed 180° spray angle makes the Rain Bird MPR-10H especially suitable for sprinklers installed along straight lawn edges. Its half-circle spray pattern helps keep watering focused on the intended grass area. This makes it useful for lawns next to garden paths, patios and other clearly defined boundaries.

The spray radius ranges from 2.1 to 3.1 m depending on operating pressure. At the optimum pressure of 2.1 bar, the nozzle reaches approximately 3.1 m. Its spray trajectory is 15°. The integrated stainless steel adjustment screw allows the radius to be reduced when required.

Matched precipitation rates for balanced watering

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 used together to provide balanced irrigation across differently shaped lawns.

The Rain Bird MPR-10H has a flow rate of approximately 2.4 to 3.0 l/min depending on operating pressure. At 2.1 bar, this corresponds to around 180 litres per hour. When planning an irrigation zone, add together the flow requirements of all connected nozzles and make sure the available water supply provides sufficient pressure and capacity.

Easy installation on Rain Bird spray bodies

The Rain Bird MPR-10H 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 a complete lawn irrigation system, the MPR-10H can be combined with suitable MPR-10Q quarter-circle and MPR-10F full-circle nozzles. These models have comparable spray radii at the same operating pressure but different spray patterns and flow rates. Pressure-regulated spray bodies are useful when the supply pressure is higher than required.

Frequently asked questions about the Rain Bird MPR-10H

What is the spray radius of the Rain Bird MPR-10H?

The spray radius ranges from 2.1 to 3.1 m depending on operating pressure. At 2.1 bar, the nozzle reaches approximately 3.1 m.

Can the 180° spray angle be adjusted?

No. The MPR-10H has a fixed half-circle spray pattern. However, the radius can be reduced using the integrated stainless steel adjustment screw.

How much water does the MPR-10H use?

The flow rate ranges from approximately 2.4 to 3.0 l/min. At 2.1 bar, the nozzle uses around 180 litres per hour.

Which sprinkler bodies are compatible?

The Rain Bird MPR-10H fits compatible Rain Bird spray bodies and shrub adapters, including models from the Rain Bird 1800 Series.

Can I combine the MPR-10H with other MPR nozzles?

Yes. It can be combined with suitable MPR-10Q quarter-circle and MPR-10F full-circle nozzles. Their different flow rates and the required sprinkler spacing should be considered during system design.

How much can I reduce the spray radius?

Rain Bird does not recommend reducing the normal spray radius by more than 25%. If a much shorter radius is needed, choose a smaller nozzle instead.
