The wetting diameter is proportional to the flow rate (and related pressure). The respective data is provided in the diagram of wetting diameters.
The Vibro Spreader designed with a center pin that vibrates in the middle of the nozzle. This vibration, together with the impingement of the water jet on the upper cap, generates the fine axi-symmetric fine droplet distribution and prevents accumulation of dirt or lime deposits in the nozzle.
Rain-Tal Vibro Spreaders are available in two models: the ordinary model (left picture) for pressure over 2 bars, and the low pressure (LP) model (right picture) that can operate at pressures from 1 bar and up.
For more details and specification view or download the product brochure.
Installation of the Vibro Spreader is possible in any orientation. The picture on the right shows the upright and upside-down options. When in upright position, the Vibro Spreader is automatically sealed against insects after water shut down.
The upside down version is extremely useful for overhead irrigation in greenhouses. In this mode the device is hanging down from an upper supply line.
