The product is available for a variety of flow rates, from 20 liter/hr (5.3 GPH) to 160 liter/hr (42.3 GPH). The nominal flow rate values are for a pressure of 2 bars (30PSI) and variations of the flow under pressure are provided in the Flow Rate Chart.A special High-Rate / Heavy Dutyvibro-spreader of 240 liter/hr is also available.
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 design includes a center pin that vibrates in the middle of the nozzle by the water flow. 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) and Low Pressure =L.P model (right picture) that can operate at pressures from 1 bar and up.
