Adjustable High Flow Dripper 0-100 L/H for Micro Irrigation

Adjustable High Flow Dripper 0-100 L/H for Micro Irrigation (Reference: 2191)

This Abrisa adjustable dripper represents the ideal solution for all your precise and modular irrigation needs. Designed for micro irrigation applications, it offers an exceptionally wide flow range of 0 to 100 litres per hour, allowing you to perfectly adapt the water supply to the specific needs of each plant. Its professional design makes it an indispensable tool for demanding gardeners, whether passionate hobbyists or horticultural professionals.

Applications and practical advantages

This adjustable dripper excels in many watering situations. For potted plants, it enables perfectly dosed localised watering, avoiding water waste while ensuring optimal hydration. Window boxes on terraces and balconies benefit from precise automated watering, ideal during absences or to maintain constant moisture levels.

In specialised crops such as orchids, bonsais or carnivorous plants, this dripper allows fine adjustment of water supply to the particular requirements of each species. Horticultural professionals use it for irrigation of nurseries, greenhouses and hydroponic crops, where precision is crucial for plant quality.

Technical design and innovation

Made from high-quality polypropylene (PP), this dripper perfectly resists UV rays, temperature variations and chemicals commonly used in gardening. Its compact dimensions of 25 x 15 mm allow discreet integration into all types of installations.

The green adjustment screw is the innovative core of this dripper. By simple rotation, it allows precise adjustment of the flow rate from 0 to 100 L/H, offering unmatched flexibility. The integrated self-cleaning mechanism effectively prevents blockages, ensuring reliable operation even with hard or particle-laden water.

Its working pressure range of 1.5 to 4 bar makes it compatible with most domestic and professional installations, whether fed by the mains or by low-pressure pumping systems.

Installation and optimal use

Installing this dripper is remarkably simple. It connects directly to a 4/7 mm micro irrigation tube thanks to its standardised fitting. For optimal installation, drill a 2 mm hole in the main tube and firmly insert the dripper up to the stop.

To adjust the flow rate, start from a closed position (screw fully tightened) then open gradually by turning the green screw anticlockwise. A quarter turn is generally sufficient to move from minimum to moderate flow. For higher flow rates, continue rotating until the desired flow is achieved.

Preventive maintenance consists of periodically checking flow uniformity and cleaning if necessary. In the event of partial blockage, completely unscrew the dripper, rinse with clean water and reassemble. The self-cleaning mechanism considerably limits these interventions.

Optimisation and expert tips

To maximise the efficiency of your installation, pair this dripper with a watering timer such as Gardena or similar. This combination enables perfectly controlled automated watering, ideal during holidays or to maintain optimal conditions in a greenhouse.

Seasonal advice: In summer, reduce watering duration but increase frequency to avoid excessive evaporation. In winter, space out watering more while maintaining a reduced flow to avoid overwatering.

For vertical or hanging crops, install these drippers in cascade respecting decreasing pressure along the line. Use pressure reducers if necessary to maintain flow uniformity along the entire length.

Avoid direct sun exposure on the adjustable parts to preserve the precision of the mechanism. Complete your installation with particle filters and quality fittings to ensure the longevity of your micro irrigation system.
