Typical faults with the spray gun: spray pattern not correct
Why is the spray pattern of my spray gun not right?
An uneven spray pattern can lead to inconsistent results when painting and affect the quality of the coating.
What can be done to improve the spray pattern?
- Cleaning according to SATA cleaning instructions: Thorough cleaning in accordance with SATA instructions ensures that all nozzles and air ducts are free of blockages and deposits.
- Set the inlet pressure correctly: The optimum inlet pressure can be precisely controlled and adjusted using a SATA adam, SATA DIGITAL or SATA air micrometer with a pressure gauge.
What are the possible causes of an uneven spray pattern?
- Contamination in the area of the air nozzle: Deposits in the horn and front bores of the nozzle lead to a redistribution of the air, which negatively affects the spray pattern.
- Incorrect inlet pressure: If the pressure is too high or too low, the spray jet can split or become smaller, which affects the end result.
