Airless Spray Systems and Its Major Benefits

[Cosmostar Tech Ltd]

When it comes to deciding on the right spray for conventional non-electrostatic painting, there are four choices available namely, low pressure, high volume, air-assisted and airless spray. Of all these, it is airless spray system which is commonly opted for, for various reasons.

First and foremost, airless spray systems offers complete transfer efficiency, apart from decent finishing quality and minimal wastage of material. Secondly, as compared to its other counterparts, airless spray system is cost effective and pocket friendly option. Here’s taking a look at some other major benefits of Graco airless sprayer systems.

Minimal waste of material

This is one of the biggest advantages offered by airless spray systems over conventional air spraying methods. As far as conventional air spray methods are concerned, they make use of high pressure jets for sending particles of atomized paint towards a surface. This, in turn, creates a “cloud” which disperses several particles into the air, thereby resulting in over spraying and wastage of material. Only a small percentage of paint is actually applied to the surface, with rest of the paint getting wasted in the collection bank of the spray booth.

To overcome wastage of material problems, most of the operators are seen using solvents, retarders or thinners, for lowering viscosity and aiding atomization. However, this process only adds to the costs, thereby creating a burden on your pocket. Graco air assisted airless sprayer systems, on the other hand, atomize the paint hydraulically sans atomizing the air, thereby minimizing the over spraying issues.

Better Efficiency and Control

As mentioned earlier in the article, airless spray systems use hydraulic pressure with the help of specially designed spray tip, when it comes to atomizing and delivering paint. And, absence of high velocity air atomizing of paint helps in providing greater efficiency and better control over the entire procedure. Also, airless spray systems use in-line fluid heaters for lowering paint velocity, in place of solvents. This, in turn, helps in retaining the physical properties of the coating, allowing uniform mil-build and coverage using heat to lower the viscosity. Using solvents for reducing paint viscosity has a direct affect on coverage capacity as solids content of the material have been compromised upon.

Cost effective and superior finish

Quality of finished product is the first thing which people lookout for while choosing spray methods. Airless spray systems, as compared to other counterparts, offer superior quality finish, that too, at pocket friendly costs. Airless spray systems also assure of minimum material wastage, thereby saving you a substantial amount of money, at the end of the day.
