Silvan Fan Technology IMPROVED FAN EFFICIENCY
POWERHEAD® Silvan’s Powerhead® air delivery system is a revolutionary and efficient conveyor that helps produce an adjustable spray-laden air stream from the 920mm fan to match the shape and height of the canopy. By directing airflow into both the upper and lower regions of the target canopy the spray laden air is drawn into the centre through a venturi effect. The result is deeper and more even canopy penetration on both sides of the leaves ensuring maximum spray coverage. Ideal for medium size trees such as stonefuit, almonds and citrus.
AXIAL FLOW FANS The next generation axial flow fan designed with curved reinforced nylon blades provides an even airflow to both sides of the sprayer. The curved blade shape substantially increases fan performance while using less horsepower resulting in greater canopy penetration and spray coverage. Adding to the fan efficiency, blade pitch can be easily adjusted to obtain the desired performance from the machine. Silvan offers a range of fan sizes from 600mm to 920mm so the sprayer can be matched to the application.
RADAK® Growers with taller crop canopies prefer the Radak® conveyor which comes in three options to suit different canopy shapes and sizes. The patented air volute design maximises the use of the airflow generated by the 920mm fan, the Radak ensures thorough coverage of the targeted canopy by directing airflow into the
foliage from underneath via the bottom wings. The venturi effect opens up the tree canopy to aid spray penetration and coverage. Ideal for tall tree crops such as macadamias, avocados, mangoes, olives, citrus and lychees. The Radak is available with different top and bottom wing combinations to suit the application.
