Understanding Pressure, Atomization, and Control

three gallons the same um with an HVLP the other one same size took 17 gallons with um an airless so it's really the cost you know in savings and product you know using um an HVLP is really going to make up the difference also you know people have probably seen me you know in some of my videos uh you know I was painting a rod iron fence right near a brand new car lot using oilbased product you know just you know not being afraid of having overspray floating out there you know um being carried in the wind you talk about just a little bit like overspray airless sprayers you'll run in a specific PSI hlp sprayers run it significantly less PSI and how does that affect overspray well obviously the more pressure you have the more uh Force you have behind those particles coming out of the spray gun and the more bounce back that you're going to get so as those particles come out of the out of the gun if they have a lot of velocity behind them it's going to be so much that they actually bounce off the substrate it's kind of I use an analogy a lot of a tennis ball if you throw tennis ball at a wall and you throw that ball overhand that Ball's going to come straight back at you well that's similar to what's happening with the airless systems is they're blasting those particles out of the gun so so fast that a lot of that is coming right back at you that's why you end up getting covered in paint Head To Toe with the turbine system it's more like tossing the ball underhand so it hits the wall and basically just drops right at the foot of the wall because there's no velocity behind it it's not going to rebound off that substrate and so by allowing the uh particles to still be finally atomized you can get them to lay onto the surface without them bouncing off and that's what makes it so much more efficient right I think a lot of it also comes down to the controls uh you know we talked a lot today about how much more control we have over the atomizer gun versus any any kind of airless gun airless guns seem to be more getting dumbed down more or less nowadays where you've got basically your most of your control is in the pump and the tip right that's really the only controls you have whereas uh with the HVLP we you've got only different tip and air cap sizes but then we can control the fan pattern widths uh within the within those nozzle sizes and we can control the fluid flow much more accurately and then when we start talking about pressures and that too right we're…
