What is air assisted electrostatic spraying?

Air assisted electrostatic sprayers produce spray droplets which are 900 times smaller than those produced by conventional sprayers. These micro droplets are carried deep into the plant canopy in a high speed air stream. The result is more than twice the deposition efficiency of both hydraulic and non-electrostatic air assisted sprayers. Electrical charging causes a natural force of attraction between the spray droplets and the plant, similar to the attraction between items of clothing created by the tumbling of a clothes dryer. The charge on the droplets is small, but the force pulling the spray towards the plant is up to 75 times greater than the force of gravity. Droplets literally reverse direction and move upwards, against gravity, when passing a leaf surface (Figure 1). This remarkable phenomenon by which the spray coats the undersides of the leaves and the backsides of the stems is known as electrostatic “wraparound.”

Air assisted electrostatic spraying Data submitted by leading universities demonstrate that air assisted electrostatic sprayers:

  • significantly increase insect and disease control
  • reduce the amount of agrichemical applied
  • reduce application waste water used by half reduce waste and off target drift by over 50% protect the environment.

BSL air assisted electrostatic sprayers allow you to cover an average of 10 or more acres per 150 gallon tank of water and chemical. With far less refill trips your return on investment will be in terms of months
