Netafim Woodpecker Jr. PCNL Pressure Compensating Dripper - 0.5gph - Red - Barbed Outlet

Netafim Woodpecker Jr. PCNL Dripper NET21520-001040 -- 0.5gph Red, Barbed Outlet, Pressure Compensating with CNL Check Valve

The NET21520-001040 Woodpecker Jr. PCNL Pressure Compensating Dripper delivers uniform 0.5gph output across a wide operating pressure range with an integrated CNL (Check Non-drip / Non-Leaking) check valve that prevents drainage through the emitter when the system is off. The pressure compensating mechanism maintains consistent flow from the first to the last dripper in the zone regardless of elevation changes or system pressure variation. The Barbed outlet configuration supports direct integration with SlimLine EZ Close Weight, Dripper Stake, and PC Spray Stake Assemblies. Self-cleaning flow path design helps maintain consistent performance through the full irrigation cycle in container, nursery, orchard, and greenhouse systems. This 0.5gph red version is the lowest flow rate in the Woodpecker Jr. barbed-outlet lineup, suited to the smallest containers or most water-sensitive crops.

Key Features & Benefits

• 0.5gph Pressure Compensating Output: Maintains consistent flow across a wide operating pressure range, supporting uniform irrigation from the first to last dripper in the zone regardless of topography or system layout.
• CNL Integrated Check Valve: The internal non-draining mechanism prevents drainage through the emitter after the system cycles off, protecting root zones from unplanned overwatering and maintaining residual system pressure.
• Red Color Coding: Quick visual identification of the 0.5gph flow rate in multi-rate drip systems, supporting efficient installation and maintenance without manual checking.
• Barbed Outlet Design: The barbed outlet configuration supports direct connection to SlimLine EZ Close Weight, Dripper Stake, and PC Spray Stake Assemblies for modular system assembly.
• Self-Cleaning Flow Path: Resists clogging through self-cleaning operation during normal irrigation cycles, reducing maintenance frequency in container and field growing environments.

Who Should Use This

Commercial greenhouse, nursery, orchard, and container growing operations using Netafim modular dripper assemblies, specifically SlimLine EZ Close Weight, Dripper Stake, and PC Spray Stake Assemblies configurations. Suitable for operators building or expanding drip systems where consistent per-dripper output, anti-drain performance, and modular compatibility are key requirements.

Compatibility

The NET21520-001040 Woodpecker Jr. PCNL operates at a minimum of 10.2psi with a wide compensating range. The Barbed outlet is designed for use with SlimLine EZ Close Weight, Dripper Stake, and PC Spray Stake Assemblies. Confirm outlet type and operating pressure requirements with your specific assembly configuration before ordering.

Frequently Asked Questions

What does PCNL stand for?

PCNL stands for Pressure Compensating Non-draining (CNL = Check Non-drip / Non-Leaking). The dripper compensates for pressure variation to maintain consistent flow, and the CNL check valve prevents drainage through the emitter when the system is off.

How do I confirm the operating pressure range for this dripper?

The Woodpecker Jr. PCNL activates at a minimum of 10.2psi and maintains compensated flow across a wide upper pressure range. Refer to Netafim's product specification sheet for the full compensating pressure window for the 0.5gph flow rate.

What is the difference between Barbed and Nipple outlet versions?

The Barbed outlet connects to flexible micro-tubing by pushing onto a barbed fitting, while the Nipple outlet uses a push-fit nipple connection for compatible stake and assembly components. Select the outlet type that matches your specific Netafim assembly configuration.

Can the NET21520-001040 be used in automated drip systems?

Yes -- the Woodpecker Jr. PCNL is designed for use in automated drip irrigation systems. The CNL check valve maintains consistent residual pressure between irrigation cycles to support reliable automated operation.
