Hydra Spray Gun

The Hydra Spray Gun, manufactured by ARAG S.r.l. (Italy, now part of Nordson Precision Agriculture), is a professional agricultural spray gun designed for extended use with minimal operator fatigue. Featuring a lock-on trigger button, 1/2″ brass swivel connector, and stainless steel and brass internals, the Hydra is built to handle pressures from 5 to 50 bar across a wide range of spraying applications.

A lever adjusts the spray pattern continuously from a wide hollow cone to a concentrated solid stream, while the sliding cone diffuser with ARAG’s MICRO-JET air-mixing technology achieves fine atomisation for low-impact application on delicate plants and crops. Seven interchangeable ceramic nozzle sizes (0.8 mm to 2.5 mm) allow the operator to tailor flow rate and droplet size to the task.

Applications

• Agricultural crop spraying — herbicides, fungicides, insecticides, growth regulators
• Horticultural spraying — greenhouse, nursery, and garden applications
• Orchard and vineyard treatment
• Weed control — spot spraying (stream mode) or broadcast (cone mode)
• Pest and disease control with fine atomisation for thorough leaf coverage
• Liquid fertiliser and micronutrient application
