Types of Astro Pneumatic Paint Guns

Astro pneumatic paint gun

Astro Pneumatic offers a wide range of paint guns designed to meet the needs of professional painters and hobbyists alike. Each type of paint gun has its own unique features and specifications, making it suitable for specific applications.

The main types of Astro Pneumatic paint guns include:

Conventional Paint Guns

Conventional paint guns are the most common type of paint gun used for automotive and industrial applications. They use a high-pressure air stream to atomize the paint, resulting in a smooth, even finish. Conventional paint guns typically have a large air consumption and require a powerful air compressor.

Popular models of conventional paint guns from Astro Pneumatic include the:

  • Astro 4008
  • Astro 5995
  • Astro 6810

HVLP Paint Guns

HVLP (High Volume Low Pressure) paint guns use a high volume of air at a lower pressure to atomize the paint. This results in less overspray and a more efficient use of paint. HVLP paint guns are ideal for use in areas with limited ventilation or for applying water-based paints.

Popular models of HVLP paint guns from Astro Pneumatic include the:

  • Astro 4100
  • Astro 5980
  • Astro 6805

LVLP Paint Guns

LVLP (Low Volume Low Pressure) paint guns use a lower volume of air at a lower pressure to atomize the paint. This results in even less overspray and a more efficient use of paint than HVLP paint guns. LVLP paint guns are ideal for use in areas with very limited ventilation or for applying high-viscosity paints.

Popular models of LVLP paint guns from Astro Pneumatic include the:

  • Astro 4200
  • Astro 5975
  • Astro 6800

Airless Paint Guns

Airless paint guns do not use air to atomize the paint. Instead, they use a high-pressure pump to force the paint through a small orifice. This results in a very high-pressure spray that is ideal for applying thick coatings or for painting large surfaces.

Popular models of airless paint guns from Astro Pneumatic include the:

  • Astro 2008
  • Astro 3900
  • Astro 4800
