Rain Bird a21550 Fine Mesh Filter Screen Spray Nozzle

Product Description

The RAIN BIRD a21550 is a fine mesh filter screen designed for use with Rain Bird 1800 series spray nozzles. Colored blue for easy identification in the field, the screen features a 0.02 x 0.02 inch mesh opening that catches debris before it reaches the nozzle orifice. This small but critical component protects the precision adjustment mechanism inside spray heads, helping maintain consistent throw radius and distribution uniformity. Irrigation technicians and landscape contractors install these screens during routine nozzle service or new system assembly.

This filter screen is intended for residential and light commercial irrigation systems equipped with Rain Bird spray nozzles. It seats inside the nozzle body at the inlet, intercepting particulate matter that could otherwise cause partial or full clogging of the orifice. Typical installation scenarios include new nozzle installations, seasonal system startups, and maintenance calls where reduced output or uneven coverage has been reported. The blue color coding helps technicians distinguish this fine mesh variant from coarser screen options during inventory management and field service.

Key Features

• 0.02 x 0.02 inch fine mesh opening filters fine particulate before it reaches the nozzle orifice
• Blue color coding allows quick visual identification of mesh grade in the field
• Designed to maintain precise radius adjustment by preventing debris-related clogging
• Compatible with Rain Bird spray nozzles for straightforward drop-in installation
• Small form factor integrates directly into existing nozzle bodies without modification

Compatibility

Designed for use with all Rain Bird spray nozzles to maintain precise radius adjustment and prevent clogging.

Installation Notes

Filter screens are typically installed or replaced by irrigation technicians during nozzle service. Shut off the irrigation zone and relieve system pressure before disassembling the spray head. The screen seats at the nozzle inlet and should be inspected and cleared of debris at each scheduled maintenance visit. Avoid using tools that could deform the mesh opening, as distortion will affect filtration performance.
