Inspectionable botton-drippers, with ranges from 1 to 8 litres/h. They are used for cultivations in the open field and container with medium lenght lines and with limited differences of level. Inside the dripper there is a little disk with a small labyrinth impressed, which helps to compensate the outlet and keep it constant, even with little pressure variations; moreover the variation of the flow limits the dirt deposit and accordingly it favours the cleanness. Botton-drippers can placed on the end of the little pipe or directly on the P.E. pipe’s line. Fittings used for stake-drippers are available for the insertion at the end of the little pipe, too.  For the use in container cultivations it is possible to fix the dripper with the suitable dripper holder stake.  Minimum requested filtering 120 mesh.

Auto-compensating drippers stop range variations in case of considerable slopes of the cultivation or important load losses of the pipe. Thanks to a special internal membrane and to the labyrinth way of proceeding, the going out water quantity keeps constant also with considerable differences of pressure. Inside the dripper the labyrinth-run creates a turbulent water motion, which removes all the little dirt deposits. Derivations with 2 or 4 outlets are available. They allow to have several exits even with one dripper, connected directly to the P.E. pipe. If these derivations are used, it is important to place a stake on the little outlet tube in order to fasten the little tube to the plant and compensate the outlet pressure, assuring the same range to all the little tubes connected at the same derivation.

Auto-compensating and anti-drainage drippers are similar to the auto-compensating ones, but with the addition of a special membrane, which close the outlet when the pressure falls below a fixed value (0,3-0,5-0,8-1,2 Bar). At the closure of the hydric flow, it prevents water contained in the pipes, from discharging into the last drippers, even with steep dripping lines. This system is very important for cultivations outside ground, which could have an excess of irrigation for the plants placed lower because of the daily repeated interventions. It is possible to use all the accessories created for the auto-compensating model.
