Sata 5000 RP vs. Sata 5000 HVLP paint gun
HVLP is a general industry terms and stands for ‘High Volume Low Pressure’ (at least 65% transfer efficiency). ‘RP’ is a SATA acronym for ‘Reduced Pressure’. Spray guns with ‘RP’ technology belong to the group of ‘compliant” guns. Compliant” means that the guns comply with the legislation of the EU VOC directive and also deliver at least 65% transfer efficiency as the HVLP do.
What does HVLP stand for?
Historically, first there were the ‘conventional’ guns which did not meet any requirements. In order to reduce VOC emissions and create a better working environment, some US states started to prescribe the use of HVLP spray guns. But as the HVLP technology is not very suitable to atomize all kind of materials, spray gun manufacturers introduced ‘compliant’ guns which also meet the 65% transfer efficiency, but at higher pressure. For instance, the increased output pressure of compliant guns usually allow better atomization of higher viscosity materials.
But what is the real difference between the SATAJet HVLP and RP when it comes to application?
(from my point of view and after several discussion with SATAJet users)
– better for basecoats
– higher air consumption (e.g. 45% higher SATAJet 3000 HVLP vs. RP)
– good for waterborne
– good for spraying pearls
– better for clearcoats
– lower air consumption
– good for higher solid materials
– good for urethanes
– in general, good for both basecoats and clearcoats
If only one (1) gun is used for both basecoats and clearcoats, then the ‘RP’ is the better choice. In general, RP is the better all around gun. Regarding paint savings: often it is said that RP guns are using more paint than HVLP. This is not really true if the guns are used for the material they are designed for.
