Comparison with general-purpose spray guns
The GFA Series spray guns are designed with the focus on unevenness reduction.
The recent trends in resin coating paint are high brightness and high gloss. While paint contains many different pigments such as glass powder and evaporated metal, spray guns have come to be required to form a thinner film with a smaller spray volume, thus making the coating surface prone to become uneven. Conventional spray guns are unable to suppress such paint unevenness although they are versatile and capable of producing particles of small diameters.
Reducing unevenness does not necessarily mean higher atomization performance.
The important thing is where particles are distributed evenly in the pattern.
Structure and features
High-density flat pattern
Entire main body made of stainless steel
Paint path structure with little paint accumulation
Thorough pursuit of unevenness reduction performance!
With general-purpose spray guns, unevenness or an irregular pattern results from thin-film, high-gloss coating with a small spray volume.
We have made thorough efforts to analyze the air flow of a spray gun and identify the causes of unevenness and eliminated those causes.
Reduction in paint consumption!
In most delivered lines, the finish quality is improved while paint consumption is reduced by 10% up to 50%.
* The reduction in the pass count due to reduced unevenness contributes more to the reduction in paint consumption than the improved transfer efficiency of the gun.
