The PC Emitter is a Pressure Compensating dripper (PC). This means that all your emitters will operate with the same output, along the same irrigation line. Even when inlet water pressures fluctuate, each emitter will operate like the one next to it. This guarantees uniform watering coverage along the entire line and is great for your garden. The PC emitter has a fixed flow rate of 24 litres per hour (at 100kPa), there is no need to do any adjusting. They will all operate the same. Applications: Pots, planter boxes, balcony, patio, and landscape applications.
