Orchard Sprayer Features CHOOSE THE RIGHT SPRAYER

Designed for professional agricultural use in orchards and vineyards, Silvan’s air assist sprayers are fitted with reliable and highly efficient air delivery systems. The axial flow fan produces a high volume of air directed deep into the canopy while avoiding damage to fruit or blooms. Canopy penetration is not a question of air velocity, but being able to displace the air that is already in place, in and around the foliage.

Non-drip flip-over nozzles are accurately positioned within the airstream to direct the atomised spray into the canopy, creating an even and consistent droplet size. This improved airstream penetrates to the heart of the canopy and reaching the highest parts of the tree. It provides excellent coverage of upper and lower leaf surfaces.

Single or two speed gearbox with neutral position for air volume adjustment

Hand wash tank

Polytuff UV stabilised, impact resistant tank

Trailed units available with single (fixed or suspension) axle or tandem suspension axle for increased stability

Galvanised chassis & frame for longer working life

Wide range of wheels to suit application and soil conditions

At the heart of Silvan trailed orchard sprayers is a diaphragm pump with brass heads and manifolds. All moving parts, excluding the diaphragm and valves, are immersed in a complete oil bath providing total protection against chemical corrosion. Silvan orchard sprayers are available with a range of 50 Bar (maximum) pumps from 67 to 249 litres per minute.

All Silvan trailed orchard sprayers are fitted with modular electric valves that provide greater control of sprayer output. They offer independent left and right section control along with pressure adjustment from the tractor cab.

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.




400L Suntuff Linkage Sprayer

The 200, 400 and 500 litre Suntuff air assist TPL sprayers are designed specifically for small orchards and vineyards, and for spray applications where high performance is required from low horse power tractors. The linkage mounted sprayer provides better balance and is particularly suited to narrow rows and smaller areas where restricted headlands make a sharp turning radius necessary.

Polytuff impact resistant U.V. stabilised tanks and fully galvanised frames ensure easy cleaning and long life. Quality components including high pressure pumps, close coupled to the gearbox and axial fan ensure years of reliable service with excellent coverage, penetration and control of pest and diseases.

The 1000L Compact Supaflo Sprayer is feature packed with an overall width of only 1.1m for spraying narrow rows in vineyards, berry crops and trellis tomatoes.
