what’s the output volume for our airless tips
An airless spray tip‘s output depends mainly on its orifice, fluid and operating pressure. Fan width controls how that output is spread across the surface. A wider fan does not automatically mean a higher flow rate.
Read the original output chart correctly
The original DINO-POWER chart states a test pressure of 140 bar and measures pattern width at approximately 30 cm from the surface. It does not identify all test-fluid conditions, so use these values as selection references, not guaranteed paint delivery on site.
| Orifice, inch | Approximate diameter, mm | Original output reference, L/min at 140 bar | Example codes |
|---|---|---|---|
| 0.011 | 0.28 | 0.42 | 211 / 311 / 411 |
| 0.013 | 0.33 | 0.60 | 213 / 313 / 413 / 513 / 613 |
| 0.015 | 0.38 | 0.80 | 215 / 315 / 415 / 515 / 615 |
| 0.017 | 0.43 | 1.00 | 217 / 317 / 417 / 517 / 617 |
| 0.019 | 0.48 | 1.30 | 219 / 319 / 419 / 519 / 619 |
| 0.021 | 0.53 | 1.60 | 321 / 421 / 521 / 621 |
| 0.023 | 0.58 | 1.90 | 523 / 623 |
| 0.025 | 0.64 | 2.27 | 525 / 625 |
The 0.023-inch diameter is approximately 0.58 mm after conversion; the earlier chart rounded it to 0.59 mm. This small rounding difference is not an alternative tip size.
The testing is through the water only. if change to the acrylic paint or other paint, the capacity will be about 3-5% more.
Compare 515 with 517—and 515 with 615
For conventional three-digit tips in this chart, the last two digits give the orifice in thousandths of an inch. A 517 has a larger opening and higher reference demand than a 515. A 615 has the same nominal orifice as a 515 but a wider fan.
The original nominal width bands at 30 cm are approximately 100–150 mm for 2xx, 150–200 mm for 3xx, 200–250 mm for 4xx, 250–310 mm for 5xx and 310–360 mm for 6xx. Actual fan edges and width depend on the fluid, pressure and tip condition. Check the specific tip series rather than assuming every manufacturer’s code behaves identically.
Match the tip to the complete system
- Start with the coating technical data sheet’s permitted airless tip range.
- Confirm the sprayer supports the required orifice while maintaining application pressure with your material and hose arrangement.
- Select a fan that suits the surface width and desired control.
- Test the pattern and film build. Use the lowest pressure that achieves the specified finish within the equipment and coating requirements. don’t set the highest pressure and keep working, which will short the lifetime of the spray tip and paint sprayer machine.
A worn tip may pass more material and overload a machine that previously supported it. A pump’s maximum free-flow rating is not the same as delivery through a working tip.
Review the DINO-POWER Model T airless tip specifications for compatibility with your gun and guard.
