Claber Self-regulating Dripper

Product Overview

The Claber Self‑Regulating Dripper (Model 91222) is a precision irrigation device designed to deliver water directly to plant roots with minimal waste. It operates at a constant flow rate of 4 liters per hour (l/h), regardless of variations in upstream pressure, thanks to its built‑in self‑compensating mechanism.

Key Features

• Self‑Compensation: Maintains a steady flow of 4 l/h even when the water supply fluctuates between 0.5 and 3 bar.
• Compact Design: Each dripper measures only 10 mm in diameter, allowing close spacing for dense planting without clogging.
• Durable Construction: Made from high‑density polyethylene (HDPE) with a corrosion‑resistant coating suitable for both fresh and slightly saline water.
• Easy Installation: Fits standard 1/4‑inch (6 mm) fittings; can be mounted on garden hoses, irrigation lines, or drip tapes.
• Low Maintenance: The internal filter is removable and washable, extending the dripper’s service life.

Technical Specifications

Installation Guide

1. Prepare the Supply Line: Ensure the main irrigation line is clean and free of debris.
2. Attach the Dripper: Slide the dripper onto a 1/4‑inch fitting. Tighten gently to avoid damaging the seal.
3. Positioning: Place each dripper at least 30 cm apart along the planting row to prevent overlapping zones.
4. Secure with Clips: Use flexible tubing clips to hold the drippers in place, preventing movement during irrigation cycles.
5. Test Flow: Turn on water and verify that each dripper releases a steady stream. Adjust spacing if necessary.

Operating Principles

The self‑compensating mechanism relies on an internal pressure chamber that balances the external supply pressure. When upstream pressure rises, the chamber expands, reducing the effective opening of the orifice; when pressure drops, the chamber contracts, allowing more water to flow. This dynamic adjustment keeps the output at a constant 4 l/h.

Applications

• Vegetable Beds: Ideal for high‑yield crops requiring precise watering.
• Orchards: Provides uniform moisture to young trees without overwatering.
• Greenhouses: Compatible with automated irrigation systems and programmable timers.
• Landscape Gardens: Enhances water efficiency in ornamental beds and lawns.

Maintenance Tips

• Inspect the dripper every 3–6 months for signs of clogging or wear.
• Clean the internal filter with warm soapy water; rinse thoroughly before reassembly.
• Avoid exposing the device to extreme temperatures (above 50 °C) which may deform the plastic.
• Store unused drippers in a dry, shaded area to preserve material integrity.

Benefits Summary

The Claber Self‑Regulating Dripper delivers consistent watering, reduces water waste, and simplifies irrigation management. Its robust construction and straightforward installation make it suitable for both amateur gardeners and commercial growers seeking reliable, low‑maintenance solutions.

Frequently Asked Questions

Can I use this dripper with a pressure regulator?

No additional pressure regulation is required; the device compensates internally. However, a regulator can further protect against extreme pressure spikes.

What water quality is acceptable?

The dripper tolerates standard tap water and mildly saline irrigation solutions. For highly mineralized water, periodic cleaning is advised to prevent scaling.

Is the product compatible with drip tape?

Yes; simply attach the drippers to the tape using the 1/4‑inch fittings or adaptors.

Conclusion

The Claber Self‑Regulating Dripper (Model 91222) exemplifies precision irrigation technology. Its self‑compensating flow, durable build, and ease of use make it a valuable component for any efficient watering system.
