Lunchbox Sprayer


The Lunch Box Sprayer was developed to replace the gas charged systems where the operators carry a pressurized bottle of gas on their backs. The lunchbox, so called due to its shape, is carried on the operator’s belt and comprises a battery powered compressor to supply the air to the chemical container. This operates at a maximum pressure of 5 bar. We also supply carbon fibre spray booms made from material developed for the aircraft industry, which gives a very light, rigid boom that is easy for the operator to use.


  • High output single pump Compressor
  • Fitted with a lithium-ion battery giving up to 75 % more spraying time per charge at a weight of only 5.5 kg
  • Designed to replace gas/air cylinders traditionally used to pressurise chemical canisters
  • Ergonomically designed backpack

  • Available in three formats: ’T‘ boom, ’A‘ frame offset & handheld offset
  • With a choice of up to 7 nozzles at various spacings, typically 500mm, plots of up to 3.0 m or 3.5 m widths can be sprayed in one pass
  • All booms come with shoulder harness, trigger, pressure regulator and pressure gauge Anti-drip nozzle holders with quick fit caps to take all standard jets are fitted to all booms
  • An adaptor is available which fits most pressurised plastic bottles from 250 ml to 3000 ml. These bottles are available at a very low cost, so many treatments can be mixed before going to the field
  • Alternatively metal canisters of 5, 9 and 11 litre capacities can be used
  • Application rates typically up to 200 litres / hectare can be achieved in one pass
