Anyone know how to change the paint filter on this gun.

Thanks Norman

I use this gun you just pull the filter out never had any problems with it

There's a little stalk on it which you pull to get it out. It's a bit tight when new but it's just a pull/push fit.

Is it the little mesh filter between the cup and the gun? If you can't see the stalk it can be awkward and you might need something to pull it out with. Soften round it with some gunwash thinners. The filters are a standard fit for most gravity guns and only cost about 70p each so not worth saving for too long.

Hi Guys,

Thanks for the advice regarding the filter will change it tonight, have you guys used 2k paint with this gun. I am fairly new to spraying and used the gun to spary the front two guards with great success. A few days later when I tried to spary the bonnet using the same setup I cannot get the paint to flow hardly at all from the gun. Have cleaned the gun farily well I think, any ideas.

Thanks Norman

Try spraying neat thinners with the filter removed, if it gives you a pattern your paint is too thick or your filter is blocked. If you filter your paint before you fill the gun you don't need the pot filter.

On some paint sites they recommend removal and binning the filter.

I've got one of those, use it for primers. Did you strip it totally after the last session? Just blowing thinners through isn't enough imo. check all the small ports are free, poke with a toothpick maybe, lots of thinners etc.
The gauze filters last a good while if you clean them after each session, no need to change it every time.

Hi guys, changed the filter tonight and it was well gummed up, busting now to have another go at the bonnet. Thanks for the advice.

Out of curiosity what pressure do u use this spray gun at for painting?

 

[andyv]

Also out of curiosity, what can you tell me about the 3rd control knob? The instructions say it's to control the volume of air input. If you turn it fully clockwise it shuts the air off altogether but once the air is flowing it doen't seem to matter how it's set. I just run it fully open. I've got another gun which doesn't have this knob at all.

Knob 1 controls the spray fan shape.

Knob 2 sets the fluid control needle.

Anybody?

phil-m - I end up around 40-45 psi but have to experiment each time. As you'll gather I'm a beginner at this though.

 

[phil_m]

Cheers mate that's the same psi set up I use with this gun. Also found that with the 3rd control knob... I use a regulator on the gun so I guess it rules out the use of the 3rd control just have it fully open

 

[andyv]

Interesting...my regulator is just downstream of the compressor, so I suppose one way of setting up the gun would be to go up to say 50 psi on the reg and then turn knob 3 down until you got almost no flow then worked back up until the spray pattern was OK. That in effect is giving the required 40-45 psi at the gun but with possibly finer control.

Would that make sense?

 

[Chipper]

35-50psi, from memory, but there's bound to be instructions on line if you lost them, at the places that flog them.

The control behind the needle adjusts the amount of paint.
One of the others changes the fan from flat to dot.
And one controls the air supply, but is pretty much useless I find, best done at the regulator. Can't remember which is which without holding the gun, but a quick play will reveal all.

The setups are very cheap, about £7 when I got mine, so you can have 1.4, 1.7, and 2.0 for high-build primer without much wallet pain.
