Pressure is the key to properly atomizing materials with an airless paint sprayer.  Pressure is also key in being able to effectively pump material over a distance.  When considering what pressure will be ideal for your airless paint sprayer, you can check your product data sheet of the products you spray.  This will allow you to verify the pressure requirements of your coatings.  One additional idea to consider is how much hose you will utilize on your airless paint sprayer.  If you will be trying to push material over 100 feet and up vertically, you need to consider using more pressure than what is required on the product data sheet.  This is to compensate for pressure drop in your airless paint sprayer hose that occurs over long lengths and heights of hose.  By reviewing your product sheet and the hose amount you will use you should be able to determine the right pressure airless sprayer you will need.

SELECTING THE RIGHT SPRAY PRESSURE:After you have chose an airless paint sprayer that will deliver enough pressure the next key with your airless sprayer pressure is using a good operating pressure.  Excessive pressure with your airless sprayer can cause excessive overspray but lack of pressure can result in airless sprayer tails. In general you want to gradually increase your airless sprayer pressure until the pressure you have chosen is high enough to eliminate any tails in your pattern and maybe slightly more pressure to ensure pressure drop doesn’t create an issue.  By starting low and gradually increasing, you can be better certain you will be using your airless sprayer at an effective pressure without creating excessive overspray.
