Netafim™ SpinNet™ Sprinkler Head Assembly with CNL - 23.4 GPM - Brown Mister, Brown Body, Blue Spinner

Drip-Free Overhead Irrigation for Greenhouses and Tunnels

The Netafim™ SpinNet™ Sprinkler Head Assembly with CNL is engineered for hanging installations where drip-less shutoff is essential to prevent unwanted water from reaching plants below after each irrigation cycle. The built-in CNL (Check Non-Leak) internal check valve stops dripping at shutoff, while the adjustable radius control lets you dial in coverage to match your row spacing and canopy width. Color-coded components — Brown Mister, Brown Body, Blue Spinner — make identification and system mapping straightforward in multi-zone installations. Interchangeable, tool-free cleaning parts reduce downtime and keep emitters performing at rated output over the full growing season.

Key Features & Benefits

• CNL internal check valve — prevents dripping after irrigation cycles shut off, protecting plants and growing media directly below the sprinkler.
• Adjustable radius control — tune the spray radius to match your specific row spacing and canopy dimensions without changing emitters.
• Tool-free interchangeable parts — disassemble and clean all components by hand without tools, minimizing maintenance downtime during the growing season.
• 23.4 GPM rated flow — calibrated output supports consistent zone-to-zone uniformity across greenhouse, net house, and tunnel layouts.
• Color-coded assembly (Brown Mister, Brown Body, Blue Spinner) — component colors simplify system identification, zone mapping, and replacement part ordering in multi-zone installations.
• Hanging installation design — overhead mounting keeps emitters above the canopy for uniform coverage without obstruction from plant growth.

Who Should Use This

Greenhouse operators, nursery growers, and tunnel farmers running overhead irrigation who need reliable drip-free shutoff to protect crops from post-cycle dripping and maintain consistent uniformity across hanging sprinkler zones.

Compatibility

Designed for Netafim overhead irrigation systems in greenhouse, net house, and tunnel applications. Verify inlet thread and lateral line compatibility with your Netafim system layout before installation.

Frequently Asked Questions

What does the CNL (Check Non-Leak) feature do?

The CNL internal check valve holds water back at the emitter after the irrigation cycle ends, preventing dripping that could damage foliage or create unwanted wet spots below the sprinkler.

How do I adjust the spray radius?

The SpinNet includes an adjustable radius control that can be turned by hand to reduce or expand spray coverage to match your row or bed spacing.

Can I clean the emitter without removing it from the line?

The interchangeable parts are designed for tool-free disassembly, allowing cleaning without removing the entire assembly from the lateral line in most configurations.

What do the color codes indicate?

Component colors (mister, body, spinner) identify the flow rate and spray pattern of each emitter, making it easy to verify the correct unit is installed and to order matching replacements.
