Spray-painting with nitrogen derived from N2-Smartspray device is a new technology on the market. It allows the end user to apply a high quality paint coating with significant savings in consumption. Compared to the previous technology where the carrier of paint on the spray gun is compressed air, nitrogen replaces it and raises the quality of painting technology to a new level.
Membrane technology is becoming increasingly popular because nitrogen generators of this type do not belong under pressure vessels. Dew point is above -40 ° C, which means that the gas is completely dry.
Paint particles in combination with nitrogen are faster (13m / s) than air (7 m / s) and need lower pressure, since the size of the paint particle with nitrogen is smaller (35 micrometers) than with air (41 micrometers) – smaller size = better color distribution on the coating surface and lower paint consumption. Prior to spray painting, nitrogen is passed through a heater inside the pipe to obtain an even better layer of paint coating.
