Product name

Pressure Compensation Dripper 4L 8L PC Dripper

Consistent Flow Clog Resistant

The Pressure Compensating Dripper delivers uniform 2/4/8 L/h flow across undulating terrain to save water and protect shrubs, fruit trees and flower beds. Its low-CV, pressure-compensating design is made from anti-UV, anti-corrosion, anti-aging plastic, features a compact openable housing for easy cleaning and operates reliably at 0.8–4 bar with >120 mesh filtration. Packed in customizable bags or cartons (6000 pcs/carton) with free samples, a 7–15 day lead time and multiple shipping options, it combines quality manufacturing with flexible delivery to meet installation needs.

Pressure-Compensated Uniform Water Flow

The Dripper is a pressure-compensating emitter offered in 2, 4 and 8 L/h that maintains uniform discharge across 0.8–4 bar with low CV and recommends filtration above 120 mesh. Made from anti‑corrosion, anti‑UV, anti‑aging plastic, its durable, serviceable construction can be opened for cleaning and fits standard fittings for shrubbery, flower beds, orchards and greenhouse irrigation, delivering efficient water-saving performance on undulating terrain. An internal compensating mechanism and compact cylindrical design ensure consistent flow under pressure fluctuations, easy on‑site maintenance, and compatibility with common drip irrigation lines and accessories.

Consistent Pressure Compensated Flow

The Pressure Compensating Dripper delivers uniform flow rates (2, 4, or 8 L/h) across varied terrain, maintaining consistent performance at 0.8–4 bar for efficient irrigation of shrubbery, flower gardens, and fruit trees. This washable Dripper is manufactured with low CV tolerances and durable anti-corrosion, anti-UV, anti-aging plastic to ensure nearly identical discharge and long service life. With recommended filtration above 120 mesh and easy access for cleaning, it provides reliable pressure-compensated irrigation for undulating landscapes.

FAQ

What does "Pressure Compensating" mean and what do the flow rates 2/4/8 L/H indicate?

Pressure compensating (PC) drippers deliver a nearly constant flow despite changes in line pressure (within the dripper’s operating range). The numbers 2, 4 and 8 L/H refer to the nominal output of each dripper in liters per hour, so a PC 4 L/H will supply about 4 liters every hour under normal operating conditions. Check the manufacturer’s specification for the exact pressure range over which the compensation is guaranteed.

In which application scenarios are PC 2/4/8 L/H drippers most useful?

They are ideal where uniform delivery is needed across long lateral lines or sloped terrain—vineyards, orchards, nurseries, greenhouses, container plantings, landscapes, and rooftop gardens. Use lower rates (2 L/H) for slow, deep watering of trees or long-duration nursery pots; medium (4 L/H) for shrubs, vines and mixed beds; higher (8 L/H) for fast-draining soils, large containers or where faster wetting is required.

How should I install these drippers for reliable performance?

Flush the main and lateral lines before installing emitters. Follow the manufacturer’s recommended hole punch size and insert the barbed emitter firmly into the tubing; stake or clip it into place to prevent strain. Maintain recommended spacing between emitters based on crop and soil (e.g., closer spacing on sandy soils, wider on clay). Install a pressure regulator and a suitable filter upstream to protect the drippers and keep pressure within the PC range.

What filtration and maintenance are required to prevent clogging?

Use a sediment filter sized for the dripper type (follow the product recommendation) and consider a screen or disc filter upstream. Periodically flush lines, inspect and clean strainers, and remove or replace clogged emitters. For hard water or fertilizer use, occasional chemical flushing or a water treatment program can reduce mineral buildup. Always follow manufacturer maintenance intervals.

Can these drippers be used for fertigation and are there any precautions?

Yes—PC drippers can be used with soluble fertilizers and most common soluble amendments. Precautions: use a well-designed injector, anti-siphon/backflow prevention, and a compatible filtration and flushing regime; monitor water chemistry (pH, EC) to avoid precipitation; and flush lines after fertigation if residues are likely. Confirm chemical compatibility with the dripper manufacturer for specialty chemicals.

What are common problems (uneven flow or no flow) and how do I troubleshoot them?

Uneven or no flow is usually caused by clogged emitters, blocked filters, incorrect pressure (too low or above the PC range), damaged tubing, or airlocks. Troubleshooting steps: check and clean/replace filters, flush the line, inspect and replace clogged emitters, verify system pressure and regulator settings, look for kinks or cuts in tubing, and purge air from high points. If issues persist, compare flows at multiple emitters to isolate the problem area and consult the product guide.
