OMA Duster 140 Tractor-mounted Sulphur Duster

The OMA Duster tractor-mounted sulphur duster is an agricultural machinery used for treatments with powder pesticides. This machine represent a great solution for sulphur treatments in the vineyards, hence the name sulphur duster.

The duster is also used to distribute copper sulphate, sulphur bentonite and general dusting products generally useful in agriculture.

The OMA Duster is towed by the tractor via a three-point-hitch. It is suitable to meet the needs of both companies and demanding users thanks to the large 100 L tank.

The tank is equipped with a mechanical shredder for powder that acts as a shaker to prevent clogging and a powder regulator to open the tank through which the powder passes.

Maximum distance that can be reached from each sprayhead: 6-8 metres

Flow rate: 4000 m³/h

Tractor power: min 20 Hp

Controls and adjustments

The Duster tractor-mounted sulphur duster is fitted with a radial fan that measures 400 mm. This fan pushes the powders, which fall and pass from the tank to the fan: between the two there is a mechanical regulator that is adjusted by a manual control.

This control gradually opens or closes the 4 regulator discs inside the tank so that only the desired amount of product can enter the fan and be expelled through the sprayheads. The powder regulator manual control comes with a 2 metres cable and can be set by the user while comfortably sitting on the tractor.

Next to the 4 regulator discs, the tank features a mechanical shredder for powder that acts as a shaker and prevents any type of clogging of the powder regulator discs.

The Duster tractor-mounted sulphur duster features a three-opening adjustable cannon spray head diffuser and metal flow deflectors.

Focus on the metal flow deflector

The three-opening head diffuser is controlled by three valves that open or close the flow of powders inside the sprayheads, allowing only one or even two the available openings to be used.
