Air Bubble Jets

Award winning, internationally renowned and industry leading range of air induction nozzles. Manufactured in Britain, these precision made LERAP 3 star rated nozzles are suitable for most sprayers including VLV, HV applications and knapsacks. Ten nozzle variations are available with application rates ranging from 20–905 litres per hectare.

  • They make the spraying activity safer for the operator
  • The sprayed pesticide is more likely to hit the spot and stay there

BFS Air Bubble Jets

Research indicates that when using air induction nozzles, spray drift can be reduced by an impressive 50 to 70%; reducing the risk to operators and the environment by reducing exposure to the pesticide from spray drift. It also means that more pesticide reaches the target surface and – because the designed drops incorporate air which cushions the drops on landing –these drops are more likely to remain on the target surface. Spray drops emitted using conventional nozzles however, are less likely to remain on the target surface as they bounce or run off thus air bubble jets are more likely to help you gain improved control in a safer manner!

– Stewardship Community,
“2 Very Good Reasons to use Air Induction Nozzles…”

How does it work?

  1. The liquid being sprayed passes through a removable tapered nozzle (A) which accelerates the liquid and projects the flow into the tapered opening of the venturi (B).
  2. This creates a vacuum that causes air to be sucked in through the slots marked (C).
  3. The mixture of air and liquid is compressed as it passes through the mixing chamber (D) and is then sprayed through the fan nozzle (E).
  4. The emitted spray contains large droplets filled with air bubbles but virtually no fine drift prone droplets. The droplets explode on impact with the target to produce similar coverage to conventional finer sprays.

  • de-icing roads,
  • pavements,
  • runways and car parks,
  • aquatic weed control on lakes and reservoirs.

Pattern types:

A blue quarter of an oval shape Short pattern: Recommended operating height of 45-90cm. Designed for either left or right hand mounting and provide an outward to downward spray pattern.

Two quarters (red and blue) of an oval shape next to each otherRegular Pattern: Recommended operating height of 45-120cm. Designed for left or right hand mounting and provides a wide spray pattern.

A blue half of an oval shapeFull pattern: Recommended operating height of 45-120cm. Designed for full left and right hand spray pattern from a single, centrally mounted nozzle.

Twin Cap

Twin Cap for Billericay Air Bubble JetsThe Twin Cap with US style bayonet fitting, designed specifically for the Air Bubble Jets, gives forward and backward-facing angles to improve spray penetration. Enabling faster speeds, higher volumes and increased crop penetration. Also suitable for use with standard flat fan nozzles.


Angled Cap (with washer):

Offers the operator the benefit of angling the spray 30°, forwards or backwards along the spray boom whilst using their existing 8mm air induction or flat fan nozzles. Angled caps eliminate the need to purchase expensive replacement nozzles.
