FAQ 01: How often do airless paint spray guns filters need to be replaced?

A. This will vary greatly on how much trash

(virtually all latex paint has some trash in it)

is in the paint and the mesh size of the filter.

(In general the finer the filter, the more often it needs to be cleaned / replaced.)

The filter meshes are made of stainless steel mesh to eliminate rust.

So you almost never replace them due to what you would consider wearing out.

What happens is either the filter becomes so clogged that it is not worth your time

to clean them.Or if the user forgets about the filter and lets enough trash build

around the filter that the airless 2800-3000 PSI pressure has no choice but to blow

a pin hole in the filter.Once a pin hole has formed, the paint sprayer filter must be replaced as the

pin-hole will allow trash to pass through and thus constantly clog your paint spray tip.

FAQ 02: How often do the airless spray gun filters need to be cleaned?

A. Normally every time the sprayer is cleaned is all that is needed.

Exceptions would be as below.

1. Your paint has an unusually high amount of “trash” or small grains.

2. When using a small paint sprayer tip and the Red Extra-Fine filters. In these cases you may

need to clean the airless sprayer gun filter during a spray job.

For example if spraying a latex paint with a small 211 tip with the Red-Extra fine airless gun filter;

you may need to clean the filter every 2 to 5 gallons.

so normally we recommend you to change to bigger nozzle size (like 517 515) and use smaller mesh (bigger hole) filter (like 60mesh 80mesh) to prevent clogging frequently.

(How often will GREATLY depend on how much trash is in the paint)

Easy way to tell the filter needs to be cleaned during spraying

(or replaced if in a hurry) is the reversible paint spray tip starts to constantly clog.

FAQ 03:What would happen if you used the wrong filter for the tip?

A. Using a larger mesh filter with too small of a tip would result in constant airless spray tip clogs.

Using a smaller mesh filter with too large of a spray tip would result in unnecessary

paint flow restriction.

FAQ 04:Should i remove the filter if I spray putty?

yes, we recommend you to remove the spray gun filter (or even the pump manifold filter) when you spray the putty or plaster.

but it’s necessary to filtering the material before spraying, if you mix the powder with water by the mixer.

because there’s maybe some powder which are not mixed totally.

the powder will clog the spray gun tip easily.
