Rain Bird ILCRBY150S high-capacity screen filter 1½-inch M thread

High-capacity filtration for larger water flows

The Rain Bird ILCRBY150S is a large-capacity screen filter designed for irrigation systems with higher water demand. Its 1½" connections and generous filtration area make it suitable for larger irrigation zones where reliable water filtration needs to be combined with high flow capacity.

The filter captures contaminants before they enter downstream pipes and irrigation components. This helps protect drippers, dripline, micro-sprays, control valves and other components from debris and supports reliable operation throughout the irrigation system.

130 micron stainless steel screen

The ILCRBY150S uses a removable stainless steel screen with a filtration rating of 130 micron, corresponding to 120 mesh. Its large filtration area provides effective water filtration while helping to extend cleaning intervals compared with smaller filters.

The screen is reusable and can be removed from the housing for maintenance. Contaminants can be rinsed away with clean water before the filter element is reinstalled, eliminating the need for routine replacement of the complete screen under normal operating conditions.

Designed for high-capacity irrigation systems

The 1½" version is designed to handle substantially larger water volumes than the smaller 1" model. This makes the ILCRBY150S suitable for larger gardens, multiple irrigation zones and professional applications where higher overall water flow is required.

The maximum operating pressure is 8 bar. The ILCRBY150S provides filtration only and does not contain an integrated pressure regulator. If downstream irrigation components require reduced or controlled pressure, a separate pressure regulator should be installed.

1½" BSP male connections

As an international Rain Bird model, the ILCRBY150S features 1½" BSP connections. Male threaded inlet and outlet connections allow the filter to be integrated into appropriately sized irrigation pipelines and distribution systems.

The durable housing is designed for irrigation applications, with Rain Bird specifying a maximum water temperature of 60 °C. Sufficient clearance should be provided during installation so that the filter element can be removed easily for inspection and cleaning.

Easy access for regular maintenance

Simple filter maintenance is particularly important in larger irrigation systems. The ILCRBY150S can be opened to inspect and clean the screen without removing the entire filter housing from the pipeline.

Rain Bird recommends installing the filter downstream of a valve or suitable shut-off point. This allows the water supply to be isolated during maintenance and prevents the filter from remaining continuously exposed to line pressure.

Frequently asked questions about the ILCRBY150S

What is the filtration rating of the ILCRBY150S?

The stainless steel screen provides a filtration rating of 130 micron, corresponding to 120 mesh, helping to prevent contaminants from reaching downstream irrigation components.

What is the difference between the ILCRBY150S and ILCRBY100S?

The main difference is the connection size and suitability for higher water flow. The ILCRBY100S uses 1" connections, while the ILCRBY150S features 1½" connections for higher-capacity irrigation systems.

Can the stainless steel screen be cleaned?

Yes. The screen can be removed from the filter housing, cleaned and reinstalled. It is designed for repeated use rather than routine disposal and replacement.

Does the ILCRBY150S include pressure regulation?

No. The ILCRBY150S is designed for water filtration only. A suitable separate pressure regulator is required when downstream irrigation components need a specific or reduced operating pressure.

What is the difference between the ILCRBY150S and ILCRBY150D?

The ILCRBY150S uses a screen filter element, while the ILCRBY150D uses a disc filter. Both models provide 130 micron or 120 mesh filtration but use different filtration technologies.

When should I choose the 1½" version?

The larger version is appropriate when the irrigation system requires higher water flow and uses a 1½" main line or corresponding connections. For lower flow requirements, the more compact 1" version may be sufficient.
