Airless guns

Airless guns are the paint guns application which atomize the paint without air (airless means without air), atomization or spray is produced by passing with high pressure paint through narrow hole, where shocks and sprayed paint.

In order to divide the paint into fine particles by impact, it is necessary that the paint acquires a high speed before impact and sprayed, this is achieved by pumping the paint at high pressures about of 400 to 500 bar.

Due to the high pressures required by the use of airless guns, it is necessary that hoses which circulate paint and the pressure pump are capable of supporting and producing the pressure range that needs the airless process. Thus airless guns are designed and manufactured with materials capable of withstanding the high pressures that are submitted.

The main advantage of the airless spray gun is the high rate of deposition of paint, or whatever it is, the high application rate achieved with this type of gun, against airless aesthetic finishes are much lower compared to finishes obtained with the conventional spray gun. This is the reason that is used in sectors such as shipbuilding, big steel structures, etc ...

Airless advantages
Airless disadvantages
    • Application of high flow of paint.

    • High application rates.

    • High deposition of paint micron in one pass.

    • Application of high-viscosity paints.

    • Lower consumption of solvents and thus less emission of VOCs.

    • High transfer rate compared to the conventional spray guns.

    • Reversible nozzles, fast and ease to clean

    • Low level of aesthetic finish compared with the conventional spray guns.

    • Need pumps and hoses for high pressure.

    • Low transfer rate compared to the airless assisted with air gun.

    • Overspray or mist greater compared to the airless assisted with air gun.


Now that you know the Airless guns, did you know Airless guns were launched in 1950 by the company Binks?, Thanks to this innovation could paint large and big surfaces such as buildings, boats and bridges with a speed unsurpassed today.
