Cobra 3c – Low pressure automatic spray gun


The DeVilbiss Cobra 3c automatic spray gun is the ideal solution for spraying camera, computer and mobile phone components and many other products.

DeVilbiss Cobra 3c is an automatic low pressure air spray gun (constant air bleed) for the application of solvent and water based paints for use on automatic reciprocator, rotary and robotic painting machines.

The gun utilises the world renowned DeVilbiss Trans-Tech or HVLP atomisation technology with hardened fluid tips and needles as standard, to provide excellent paint compatibility on a wide variety of applications. All fluid passageways in the automatic spray gun are constructed from high grade stainless steel and the spray gun uses a micrometer needle adjustment knob for fine and accurate fluid flow control.

The spray gun requires remotely positioned air valves (not supplied with the  spray gun) to control the air supply for gun triggering, atomisation and fan size adjustment.


  • Fast maintenance and serviceability
  • Quick easy cleaning of external parts and internal passageways
  • Air cap indexing for consistent application repeatability (option)
  • Fast on/off operation of fluid needle
  • Independent fan, atomising and triggering air for total machine compatibility.
