Paint spraying using airless sprayer equipment

Airless Spray Tip Data

Airless spray tips are ususally numbered in thousands of an inch with a single digit in front indicating the angle the tip is cut at which determines the paint spray pattern width.

The following airless spray tip charts may help out with metric conversion and airless spray tip flow rate reference data.


Piston Airless Valve Diagnosis

Diagnosing problems with airless piston pump pressure valves.

Here is a way to test your piston airless spray pump to ensure the inlet valve and outlet valves, including the relief valve are functioning correctly.

This test is much easier to do and see the results with a large longer stroking airless piston pump compared to a small short stroke fast cycling piston airless sprayer.

A small airless spray tip that slows the output of the airless piston pump will make this test easier to read.


Cleaning Your Airless Sprayer

A most common cause of airless spray gun problems and early failure are a result of incorrect cleaning and airless paint sprayer storage procedures.

When your airless paint spray job has completed the first step is to recover as much of the remaining paint that still remains in the airless spray unit. Consult your airless paint sprayer operation manual for the recommended procedure to remove any remaining paint from the airless machine and to properly flush the airless unit out.


Airless Sprayers

Airless sprayers are an excellent method of applying decorative and protective paints or coatings to almost any surface quickly. Airless spray paint units when correctly setup are also capable of providing extremely high quality painted finishes.

Almost any type of paint or coating can be applied using an airless spray unit. Thin products such as stains, timber preservatives, lacquers, polyurethanes and enamels can be applied using an airless sprayer provided the correct filtration, spray tip and pressure setting is used.
