The Rain-Jet Supertif Pressure Compensated (PC) Drippers (5-Pack) are high-performance irrigation emitters designed for precision water delivery in orchards, vineyards, and greenhouse environments. The 3.8L/h flow rate provides a consistent, medium-volume soak that is ideal for larger shrubs, young fruit trees, and intensive vegetable gardening in the Heidelberg - GP region.
Technical Specifications
- Flow Rate: 3.8 Liters per hour (L/h).
- Type: Pressure Compensating (PC) – maintains a steady flow despite pressure fluctuations.
- Inlet: 4mm tapered barb (Self-piercing into HDPE or fits into 4mm micro-tube).
- Operating Pressure: Recommended 0.5 Bar to 4.0 Bar.
- Material: UV-Stabilized Engineering Plastic.
- Color Coding: Brown/Tan (Industry standard for 3.8L/h - 4.0L/h identification).
Key Performance Features
- Pressure Compensation: Unlike standard drippers, the Supertif features an internal silicone diaphragm that regulates the flow. This ensures the first dripper on your line delivers the exact same .8L/h$ as the last dripper, even on sloped terrain or long pipe runs.
- Self-Cleaning Mechanism: The turbulent flow path and flexible diaphragm help flush out small particles of grit and scale, making it highly resilient to the mineral-heavy water typical of the Gauteng region.
- No-Drain (ND) Compatible: These drippers are designed to seal shut when the Pascali Pump stops, preventing the lines from draining out and ensuring an "instant start" for the next irrigation cycle.
- UV Shield Technology: Formulated to resist the intense African sun, ensuring the housing doesn't become brittle or crack during the dry Winter Bulk 2026 season.
- Chemical Resistance: Resistant to common agricultural fertilizers and acids, allowing for "fertigation" (liquid feeding) directly through the irrigation lines.
Installation & Professional Tips
- Direct Installation: Use a 3mm or 4mm irrigation punch to create a hole in your 20mm or 25mm HDPE main line. Push the black barbed side of the Supertif directly into the pipe until it "snaps" for a leak-proof seal.
- Micro-Tube Extension: For precise placement at the base of a plant, attach a length of 4mm micro-tube to the dripper outlet and secure it with a plastic stake.
- Filtration is Key: While self-cleaning, these precision devices can still be damaged by large stones or organic matter. Always install a Kaufmann Y-Strainer upstream to protect your investment.
- Pump Pairing: When calculating your total L/h demand for a 0.37kW Pascali Pump, remember to multiply the number of drippers by 3.8. (e.g., 100 drippers = 380L/h or 6.3L/min).
- Seasonal Check: During the Easter 2026 maintenance window, run the system and visually inspect each dripper. If one is underperforming, a gentle tap or a quick soak in a weak vinegar solution will usually clear any lime-scale buildup.
Common Use Cases
- Orchards: Placing 2–4 drippers around the drip-line of fruit trees for deep, consistent soaking.
- Vineyards: Ensuring every vine receives an identical water ration on undulating hills.
- Landscape Beds: Providing a hidden, high-efficiency watering solution for ornamental shrubs.
- Container Gardening: Automated watering for large pots and planters on patios or in nurseries.
Pro Tip: If you are using these drippers on a system with very high pressure, the "Pressure Compensating" feature will protect the plants, but the internal diaphragm will be under stress. For the best longevity, use a pressure regulator to keep the system between 1.5 and 2.5 Bar. Always keep a spare Pack of 5 in your Kaufmann tool chest for quick field repairs.
