Anest Iwata Air Gunsa AZ3 HTE-S Impact Chrome Gravity Feed Spray Gun (1.2mm - 2.0mm Nozzle Size + 600ml Cup)

The AZ3 HTE S Impact series offers different configurations to suit various painting styles and compliance requirements. The HTE versions (HTE S1 and HTE S2) are designed for high efficiency and consistent, high quality atomisation. The HVLP (High Volume Low Pressure) versions are specifically engineered to comply with strict environmental mandates regarding transfer efficiency. The HVLP models operate at a lower inlet pressure, designed to achieve 0.7 bar of air pressure at the centre of the air cap. When choosing between them, consider whether your workflow prioritises maximum speed and atomisation (HTE) or maximum material transfer efficiency and compliance (HVLP).

For the best results with the AZ3 HTE S Impact series, we recommend a paint viscosity between 12 and 23 seconds when measured using a Ford cup number 4. Achieving this viscosity is crucial because the gun is calibrated to atomise paint effectively within this range. If the paint is too thick, you will struggle to get an even finish and may experience an intermittent spray pattern. If it is too thin, you risk running or sagging. Always ensure your paint is mixed according to the technical data provided by your paint supplier before pouring it into the 600ml gravity cup.

Yes, the HVLP model has specific requirements to ensure it functions within its compliance mandates. While the HTE models offer more flexibility with inlet pressures, the HVLP Impact variants must be set up to ensure you achieve exactly 0.7 bar of atomising pressure at the centre of the air cap. It is essential to monitor your inlet air pressure carefully and adjust it to meet this requirement. Failing to set the correct pressure will prevent the gun from delivering the material transfer efficiency that the HVLP design is intended to provide, potentially leading to poor finish quality.
