Accuspray is different from other HVLP guns because it is made specifically for HVLP. It is designed for low pressure performance. The difference with Accuspray is that it has a large air passage that eliminates turbulence in the stream.
With Accuspray, air both enters and leaves the process area at the same pressure: 10 psi or less. This eliminates overspray.
Accuspray transfer efficiency averages at about 70% to 90%. It saves you not only 30% to 50% in coating cost over conventional guns, but 20% to 40% over other HVLP guns.
