WHAT IS AIRLESS SPRAY "AIRLESS"? HISTORY AND CURRENT AFFAIRS
It may seem like a recent invention but the act of spraying paint has been around for thousands of years. In fact Stone Age man used hollow reeds to spray pigments to create rock art.
But as with most technologies spraying has evolved and advanced over time.
There are currently four main types of spray delivery methods:
• Air spray systemsAEROGRAPHICSuse highly pressurized air created by a compressor to atomize the fluid being sprayed and apply it to the work surface
• High volume and low pressure systems orHVLPThey also use compressed air but in a different way than standard air spray systems. In the case of HVLP sprayers a turbine supplies a large volume of air at a much lower pressure to atomize and pulverize the fluid.
• Spray systemsAIRLESSwithout air they do not need a compressor or turbine instead of relying on air. These systems use a pump to supply high-pressure fluid to the spray nozzle offering fast speeds and distributing the widest variety of materials.
• The core systems air-assisted MIXEDCombine airless spraying methods and with air to an airless spray fan compressed air is added to lighten the spray range.
When it comes to achieving professional paint results being able to quickly apply the coating you are using evenly and consistently is what makes the difference.
AIRLESS airless spraying allows you to do just that in addition to beingfasterAnd easy to use that abrush or a roller.
In fact using a sprayer without air is up toten times fasterThan using a brush and at least four times faster than a roller.
So how is spraying achieved without air?.
It reaches this speed by atomizing or dividing the fluid into small droplets without the use of compressed air.
Instead, the fluid is pumped at high pressure through a spray nozzle.
The fluid emerges from the nozzle as a high-speed solid current but when that current comes into contact with the air it is altered and the fluid separates into very small droplets that form the spray pattern.
If you have ever placed your finger on the end of a garden hose you created a very simple form of airless airless spraying.
Since 1958 when Graco InventedAirless spraying professional contractors have preferred this method for many reasons.
· VelocityBecause spraying without air is faster. More work can be done in less time using less manpower.
· QualityAirless sprayers generate a uniform layer of paint known as the accumulation of thousandths of an inch on any type of surface leaving a high-quality finish.
· VersatilityAirless sprayers can be used for a wide range of coatings in both indoor and outdoor work and can be easily transported between job sites.
