Hi guys,

 

Need a bit of advice, i've got a HVLP spray gun and if you know how they work, you'll know that it requires about 10-12psi at the nozzle, from about 25psi coming in to the gun. Now my question is, is the 25psi at spray gun rest or when the trigger is pulled.

what gun you got ? u can by an adgustable preasure reg that goes on ya gun then the hose goes on it , really you shud have one anyway ! I always spray on 2bar !

also I believe you need an inline water seperator

both you have missed the question asked!

 

Rich is asking whether the pressure gauge should read 25psi without spraying or 25psi when you are spraying. nothing about water seperators or regulators

Ken, Vijay Hi,

 

I have an adjustable pressure gauge on the gun, which i can set to limit the psi going in, brings me back to my first question. My system has a water separator, which also has a gauge which is where i isolate the gun side. Here's some pics

 

1st is my humble work area

next is my compressor and entrance to spray area.

next is my in line water separator.

follow the air line round

to the end where i have a 5m flexible pipe for attachment to spray guns etc.

More pics, spray gun with attached regulator gauge. As you can see the Gun clearly states HVLP and max 20psi. I got the Guns from USA , Viper. pretty good.

I would say 20 PSI on the gauge going into the gun...

so when it's at rest, should still be 20 PSI with the trigger pulled if that's what you've set your compressor at...

what the gun reg says when you compress the trigger is what preasure your laying the paint on with ! didnt understand tbe question at first ! to set my presure I press the trigger an adjust the gun reg gauge !
