How does an airless sprayer work?
An airless sprayer works by pumping paint at a very high pressure, up to 3,000 psi, through a hose and out a tiny hole in the spray gun tip. The tip is designed to break up the paint evenly into a fan-shaped spray pattern of tiny droplets.
What controls the paint flow from a spray gun?
The fan control, commonly found on the side of the spray gun body, adjusts the amount of air distributed to the different drillings or air passages in the air cap. The air passages that are located around the fluid nozzle are the atomization air passages.
How do airless sprayers prevent runs?
If using airless paint sprayers– If you’re getting runs with an airless paint sprayer you can either move the sprayer further back from the product surface and or consider using a smaller tip size.
Does an airless sprayer use more paint?
Airless paint sprayers are extremely popular, but also tend to waste more paint on average than other types of spray guns. Your run-of-the-mill airless paint sprayer will waste up to 40% of the paint that you use, and even more if you aren’t operating the spray gun properly.
Do you need to thin paint for airless sprayer?
They’re extremely viscous, so whenever you spray them with a handheld, HVLP, or small airless sprayer, you need to thin them down. That’s true when you’re using anything other than a big airless unit. If you’re using a handheld or HVLP system to paint, you’re probably going to have to use as much as 20-30% water.
How do you reduce pressure and flow drop in an air hose?
Additional ways to minimize pressure drop include:
- Properly design the distribution system.
- Maintain air filters and dryers to reduce the effects of moisture, such as pipe corrosion.
- Select aftercoolers, separators, dryers and filters that have the least possible pressure drop for the rated conditions.
How do I get a smooth finish with an airless sprayer?
Just wait till the paint is dry and lightly sand it with a fine grit sanding block to smooth it over. Paint over it again and you should be good to go! Here’s a quick video to demonstrate how I spray paint and get a flawless finish every time.
Why is my airless sprayer leaving lines?
The main causes of streaks and disturbances in the spray pattern when using Airless devices are: Pressure set too low. Nozzle worn. Material supply disrupted (eg clogged filters)
Is airless or HVLP better?
Vertical spraying: An HVLP is better for vertical spraying small projects than an airless, especially if you’re new to spraying. You’re far less likely to get paint runs because you’re spraying at a much lower pressure. An airless cranked up to 2,000 PSI throws a lot of paint onto the surface quickly.
Are airless paint sprayers any good?
As a general rule, airless paint sprayers, because of their extremely high pressures, handle thick paints, such as latex, better than other types of paint sprayers, and usually without any need to thin the paint before use.
