Netafim™ Woodpecker Jr. PCNL Pressure Compensating Dripper – 0.5 GPH, Red, Nipple Outlet

The Netafim™ Woodpecker Jr. PCNL Pressure Compensating Junior Dripper is a precision irrigation emitter designed to provide uniform water and nutrient delivery in greenhouse, nursery, container, orchard, and other professional drip irrigation systems. Its pressure-compensating design helps maintain consistent flow as inlet pressure changes within the system's recommended operating range.

This red Woodpecker Jr. PCNL model provides a nominal flow rate of 0.53 gallons per hour (commonly designated 0.5 GPH) and features a nipple outlet designed for use with compatible multi-outlet dripper assemblies.

An integrated CNL check valve and non-draining mechanism helps prevent water from draining from irrigation lines after the system shuts off. This can reduce refill time and improve performance in applications using frequent or short irrigation cycles.

The Woodpecker Jr. also incorporates Netafim's pressure-compensating and self-cleaning design principles to support dependable flow and clogging resistance in demanding commercial irrigation environments.

What Is the Netafim Woodpecker Jr. PCNL Dripper Used For?

The Netafim Woodpecker Jr. PCNL is a pressure-compensating point-source dripper used to deliver controlled amounts of water and dissolved nutrients directly to plants or to multi-outlet distribution assemblies.

Its pressure-compensating design is particularly useful in irrigation systems where pressure can vary because of line length, elevation changes, system layout, or the number of emitters operating at one time.

The nipple outlet allows the dripper to connect with compatible tubing and multi-outlet dripper assemblies, making it useful for container production, greenhouse benches, nurseries, orchards, and other installations where one pressure-compensating emitter may supply multiple irrigation points.

Key Features and Benefits

• Pressure-compensating performance: Helps maintain uniform water and nutrient flow as inlet pressure changes within the recommended operating range.
• 0.5 GPH flow class: Provides a nominal flow rate of approximately 0.53 gallons per hour.
• CNL check valve: Integrated check valve helps prevent drainage from irrigation lines when the system shuts off.
• Non-draining mechanism: Helps keep irrigation lines charged between cycles for faster system response when irrigation restarts.
• Supports pulse irrigation: Reduced drain-down can improve efficiency in systems using frequent, short-duration irrigation cycles.
• Self-cleaning flow path: Designed to help flush contaminants and support reliable long-term emitter performance.
• Nipple outlet: Designed for connection to compatible micro-tubing and multi-outlet dripper assemblies.
• Red color coding: Provides quick visual identification of the 0.5 GPH flow configuration.
• 10.2 PSI minimum operating pressure: Designed to provide pressure-compensating performance once minimum system pressure requirements are achieved.
• Uniform irrigation: Helps deliver consistent water and nutrients throughout commercial growing systems.
• Point-source irrigation: Allows water to be directed precisely to individual plants, containers, or distribution assemblies.

Pressure-Compensating Water and Nutrient Delivery

Pressure-compensating drippers are designed to maintain a relatively consistent flow rate even when inlet pressure varies throughout an irrigation system. This is particularly valuable in large greenhouse and nursery installations, long irrigation laterals, and sites with elevation changes.

By helping maintain consistent output from emitter to emitter, the Netafim Woodpecker Jr. PCNL can support more uniform irrigation and nutrient delivery throughout a growing area.

CNL Check Valve and Non-Draining Design

The Woodpecker Jr. PCNL incorporates a CNL internal check valve that helps prevent water from draining out of the irrigation system when pressure drops after shutdown.

Keeping the lines charged can reduce the time required to refill the system at the beginning of the next irrigation cycle. This is particularly beneficial in pulse irrigation and other applications involving frequent, short watering cycles.

The non-draining feature can also help reduce differences in irrigation timing between emitters located near the beginning and end of an irrigation line.

Self-Cleaning Design for Reliable Performance

Netafim pressure-compensating drippers are designed with a flow path and continuous self-flushing action intended to help contaminants move through the emitter rather than accumulating inside it.

This design helps improve clogging resistance and supports consistent emitter performance in greenhouse, nursery, orchard, and other commercial irrigation applications.

Nipple Outlet for Multi-Outlet Dripper Assemblies

This Woodpecker Jr. PCNL configuration features a nipple outlet and is specifically designed for use with compatible multi-outlet dripper assemblies.

A multi-outlet assembly can allow the output from a single pressure-compensating dripper to be distributed to multiple irrigation points. This can be especially useful for containers, nursery pots, greenhouse benches, and other growing systems where several individual plants require controlled irrigation.

Ideal Applications

The Netafim Woodpecker Jr. PCNL Pressure Compensating Dripper is well suited for applications including:

• Commercial greenhouses
• Plant nurseries
• Container production
• Greenhouse benches
• Orchards
• Controlled-environment agriculture
• Fertigation systems
• Pulse irrigation systems
• Point-source drip irrigation
• Multi-outlet dripper assemblies
• Applications with varying system pressure
• Systems requiring reduced line drainage between cycles

Frequently Asked Questions

What is the Netafim Woodpecker Jr. PCNL Dripper?

The Netafim Woodpecker Jr. PCNL is a pressure-compensating irrigation dripper with an integrated CNL check valve. It is designed to provide controlled water and nutrient delivery while helping maintain consistent flow as system pressure changes.

What is the flow rate of the red Netafim Woodpecker Jr. dripper?

The red Woodpecker Jr. PCNL model has a nominal flow rate of 0.53 GPH. It is commonly identified commercially as a 0.5 GPH dripper.

Is the Netafim Woodpecker Jr. pressure compensating?

Yes. The Woodpecker Jr. PCNL is a pressure-compensating dripper designed to help maintain uniform flow as inlet pressure varies within the recommended operating range.

What does PCNL mean on a Netafim dripper?

PCNL refers to a pressure-compensating, non-leak or non-draining configuration. The pressure-compensating mechanism helps regulate emitter flow, while the integrated check valve helps prevent the irrigation system from draining after shutdown.

What does the CNL check valve do?

The CNL internal check valve helps prevent water from draining out of the irrigation lines when system pressure falls. This helps keep the system charged between irrigation cycles.

Why is a non-draining dripper useful?

A non-draining dripper can reduce system refill time when irrigation restarts. This is particularly beneficial for pulse irrigation and short-duration irrigation cycles, where rapid and consistent startup can improve irrigation uniformity.

What is the minimum operating pressure of this dripper?

The listed minimum operating pressure for this Woodpecker Jr. PCNL configuration is 10.2 PSI.

Does 10.2 PSI mean the dripper always operates at 10.2 PSI?

No. 10.2 PSI is the listed minimum operating pressure for this configuration. The pressure-compensating mechanism is designed to regulate flow as inlet pressure changes within the manufacturer's recommended operating range.
