UNDERSTANDING TIPS:

The Pump Delivers:
• Paint flow
• Paint pressure
Pump and tips image

 

The Tip Defines:
• Spray angle
• Spray volume

THE SECRET BEHIND THE NUMBERS:
(All tip specifications are measured 30 cm away from the surface)

The first digit describes the angle, i.e. 6 = 60°.
Multiply first digit by 5 to get the actual fan width when spraying 30 cm away from the wall, i.e. 5 x 5 = 25 cm.

The 2nd and 3rd digits describe the orifice size, i.e. 21 = 0.021".

 

 

 

ADJUSTING TO THE RIGHT TIP:
Basic rule:  when switching tips, adjust to the new fan width and new orifice size. Together. e.g.: 517 - > 619

PROBLEM SOLUTION
Tips spray angles

 

WHEN TO REPLACE A TIP?
A spray tip controls the amount of fluid sprayed by using different orifice sizes. The shape of the orifice on the other hand, determines the spray pattern. The chart below explains the impact of tip wear on the quality of your job.

What is Tip Wear?

1)   FAN WIDTH DECREASES = MORE PASSES NECESSARY = MORE LABOUR
+
2)   ORIFICE SIZE INCREASES = MORE PAINT COMES OUT = MORE MATERIAL COST


TOTAL: TWICE THE LABOUR! + 30% MORE PAINT FOR THE SAME SURFACE!

INCREASED TIP WEAR:

Fan widths

 

TIP WEAR CHART:

FAN WIDTH - NEW TIP FAN WIDTH - WHEN WORN
5cm 4cm
10cm 8cm
15cm 12cm
20cm 15cm
25cm 20cm
30cm 25cm
35cm 30cm
40cm 35cm
45cm 40cm

* These are recommendations only.
* Paint abrasion and pressure are the two variables increasing wear speed.
