Airless sprayers are typically rated using these methods:
- Maximum tip size (with one gun, with two guns, etc.)
- Liter per minute (lpm)
- Pounds per square inch or the maximum pressure (psi)
- Horse power (hp)
Lpm(Liter per minute )/gpm—(gallons per minute) a flow rate measurement associated with thepump’s output capacity and the tip orifice (hole) size. There is no industrystandard for rating a sprayer’s output capacity.
psi—(pounds per square inch) a pressure measurement.
The pressure rating (e.g., 3300 psi) is the maximum working pressure (stall
pressure) of the sprayer. That is, the maximum amount of pressure the
sprayer is able to build. However, the pressure at the tip does not equal the
maximum working pressure. Hose length, tip size, the type of coating being
sprayed, and even the filters impact the amount of pressure available at the tip
Typical maximum airless sprayer pressure ratings:
- 2000 psi
- 2800 psi
- 3000 psi
- 3300 psi
- 4000 psi
Typical atomization pressures needed for airless applications:
- 800-1100 psi for lacquers
- 1200-1800 psi for stains
- 2000+ for latex coatings
hp—(horse power) a performance rating for the sprayer’s motor or engine.
There are a variety of motor types, operating speeds and torque capabilities
available. This makes horsepower a confusing rating method for distributors
and end-users alike. Some contractors prefer to have the biggest motor
available because they believe it means more power and longer sprayer life.
This is not necessarily true, the motor and sprayer should be matched to the
Overall, the tip size rating is the most useful rating method for selecting tips
and sprayers for your job.
Maximum Tip Size—a rating that indicates the largest tip size (i.e., orifice) a sprayer is capable of supporting, while maintaining a good spray pattern.
The maximum tip size will depend on the type of coating being sprayed and
the amount of pressure needed to atomize the coating.
