Did some spraying today.
I set my airless pump at lowest pressure I thought I could go about 1000psi / 70bar fluid pressure
Sprayed on my wall and as you can see I got tails. Two lines either side of the spray pattern.
So if it was just airless I can either increase the pressure a lot more like 2000psi or higher on the fluid pressure and get rid of the tails or thin the paint down so it sprays out easier or change tip size.
OR
because it’s an AAA setup I can add air to the tip. The middle spray pattern in the picture is same fluid pressure all I done was add a little bit of air and it’s got rid of the tails
Now what are the benefits to this.
I have less fluid pressure so less wear on the pump.
I have less pressure this means less overspray and dust in the air.
I have a finer spray
I can control my spray width from the widest the flat tip lets me down by 2/3 it’s width with out the need of changing over tips for different fan widths.
I have more fluid control so I don’t have so much fluid flying out like you do with airless. Which is good for smaller narrow parts.
