What is air-assisted airless?
An air-assisted airless sprayer pumps paint under a very high pressure (around 3000 psi) through a small hole in the sprayer’s nozzle that atomizes the paint. Airless spray is a painting technique that simplifies the painting process.
What is the main advantage to using an airless sprayer over a compressed air sprayer for a painting project?
One of the biggest benefits to an air airless paint sprayer is the ability to provide a finer atomization of coatings. By adding assist air into the fluid stream you achieve a finer break up and finish than you usually will using an airless paint sprayer.
Are air or airless paint sprayers better?
Air spray is best for products requiring a high-quality finish, but doesn’t have a good transfer efficiency rate. Airless has a higher transfer efficiency rate and is often used for protective, rather than decorative coatings. Air-assisted airless offers high production levels and a high-quality finish.
Do airless sprayers create overspray?
The big benefit of an airless is the faster rate at which it sprays. However, because it uses high pressures when spraying, a lot of your paint can become overspray.
What is a good size air compressor for spray painting?
Look for two-stage compressors that deliver close to 20 CFM. Air pressure: As mentioned above, pressure (psi) is less important in an air compressor for painting cars than CFM is.
Air-assisted airless, under ideal conditions, combines the best features of air spray along with the best of airless. Air-assisted airless spray guns first partially atomize the fluid with a special fluid nozzle tip similar to a standard airless tip.
What is the difference between compressed air and airless atomization?
Atomization air pressures are usually low, under 20 psi, and as a result, this system provides a fine finish with most coatings approaching that of compressed-air atomization. With air-assisted airless we can see an approximate 30% improvement in transfer efficiency over compressed air.
What is HVLP air-assisted airless?
Newly designed low-pressure, air-assisted airless systems are also available. Some systems restrict the atomizing air pressure to comply with various EPA guidelines; as a result, these systems can be considered HVLP air-assisted airless. The primary advantage of air-assisted airless is its “soft” spray atomization.
What are the advantages of airless spray coating?
The primary advantage of air-assisted airless is its “soft” spray atomization. Atomization air pressures are usually low, under 20 psi, and as a result, this system provides a fine finish with most coatings approaching that of compressed-air atomization.
