Paint sprayer has moved many steps from the use of airbrushes to spray guns. The initial sprayers were cumbersome and had different challenges, which made innovators make more automated tools. Just as the paint has also evolved since time immemorial, the tool to apply the paint has also been invented and reinvented to the current tools.
The history dates back to the 18th century where Joseph Binks developed the first sprayer. It was handheld and its main function was to apply whitewash to the walls of the store where he was the supervisor at Marshall Field’s Wholesale Store in Chicago. The sprayer could only handle water-based paint, which was the white wash. In 1893, Francis Davis Millet, integrated the sprayer to make a simpler sprayer which used oil-based paint. Four years after the Second World War, Edward Seymour designed a more complex sprayer, which used the concept of aerosol. Aerosol paint was ejected out by compression method in a can.
It was after this spray gun where painting using compressing tools took center stage and more sprayers were developed but with no new concept but just the method of painting and the equipment for holding the paint. These traditional methods could not handle bulk-painting tasks within a short time.
This equipment is a gun with an air compressor, paint bowl, and a nozzle. Once the paint is poured into the basin, the button triggers the compressor to mix it with steam air and the paint comes out in a gaseous state. The air pressure system ejects the steam at desired position and various patterns can be formed since you are able to regulate the amount of spray.
High Volume Low Pressure (HVLP)
This sprayer uses the science of high volume leads to low pressure. The gun compresses air to give a high volume of air mixing with paint at low pressure. At the end, paint comes out at high-pressure ideal for bulk painting.
Low volume low pressure (LVLP)
This concept ensures there is maximum paint ejected out when the air is compressed at low volume under low pressure exerted by the compressor.
After the conventional spray painting with volume and pressure differences, the inventor used electrostatic painting technique. This was ideal for spraying an outer layer of automotive.
All these sprays used cold paint, due to its share of challenges there was the invention of boilers in the compressors to create pressure differences to regulate the amount and level of paint ejected in the nozzles. This was to remove airless paint, which penetrates joints, cracks, and bends. The system is automated using hydraulic power system. They are of two types, battery powered airless sprays and electric air sprays. They use the same concept but produces a spray of small thickness. It is believed to reduce wastage and since most of the functions are automated, the painting process is faster.Check reviews before buying paint sprayer because It has evolved from manual systems to the current electric and automated sprayer guns.
