Our PC drippers are constructed with wide water passages (based on the NETAFIM patented labyrinth pattern) and a free floating diaphragm designed to regulate the volume of water.

The diaphragm is activated by the continual differential pressure created by the labyrinth, thus maintaining constant dripper flow over a wide pressure range.

Thanks to the free floating diaphragm. The dripper's action is precise, immediate, sensitive and continually self- adjusting. Water entry into the dripper is through a finely engineered filter, designed to prevent dirt particles from entering the water passages.

Any particles which might cause clogging will either be flushed out through the wide water passages, or increase the pressure differential, causing the diaphragm to momentarily increase the cross- section volume for outgoing water and flush the dirt out of the system.
