| Uses medium to high air pressure injected into a stream of paint to atomize. |
| Advantages | Limitations |
| Flexibility | Transfer efficiency |
| Sprays all coatings | Flow rate |
| Low pressure | |
| Low cost | |
| Low maintenance | |
| High quality finish | |
| Can use small quantities |
| Benefits |
| Easy to use |
| Reduced cost to operate/maintain |
| Low initial cost |
HVLP
| Uses high volume low pressure air injected into a stream of pain to atomize. |
| Advantages | Limitations |
| Flexibility | Transfer Efficiency |
| Improved T. E. | Flow Rate |
| Low Pressure | Solids Content |
| Low Cost | |
| Low Maintenance | |
| High Quality Finish | |
| Can use small quantities |
| Benefits |
| Easy to use |
| Reduced cost to operate/maintain |
| Lower cost per square foot to apply |

Air Assisted Airless
| A combination of air spray and airless. Uses medium hydraulical pressure through an elliptical nozzle and "Horm Air" to atomize. |
| Advantages | Limitations |
| Speed Of Application | Medium Pressure |
| Improved T. E. | Flexibility |
| Sprays Most Coatings | Not for Small Quantities |
| Almost no air in spray pattern | Must heat coating for higher solids |
| Very Good Finish | Tip Plugging |
| Not for fine finish applications |
| Benefits |
| Low cost per square foot to apply higher mils |
| Coating costs are reduced on high volume coating applications |
Airless
| Uses high hydraulic pressure to force coating through a small elliptical shaped nozzle to atomize. |
| Advantages | Limitations |
| Speed Of Application | High pressure |
| Improved T. E. | Flexibility |
| No Air In Spray Pattern | Higher initial costs |
| Sprays most coatings | Not for small quantities |
| Plugging tips | |
| Must heat coating for high solids | |
| Not for fine finish applications |
| Benefits |
| Low cost per square foot to apply higher mils |
| Coating costs are reduced on high volume coating applications |
Electrostatic
| Uses up to 80KV to apply opposite charge on coating from grounded part. Coating is attracted to the part. |
| Advantages | Limitations |
| Best Possible T. E. | Higher initial cost |
| Speed of Application | Does not work on non conductive substrates without prep applications |
| Works with all application equipment | Requires additional training and maintenance |
| Costs Edges | Requires special accessories to spray highly conductive coatings |
| Benefits |
| Lowest cost per square foot on any spray processes |
| Quality improvement |
| Can cause labor reductions |
