I have a air compressor large enough to do Pneumatic gigs such as nailing and stuff BUT way to small to do any kind of spray finishing. Takes longer to pressure back up than it sprays.

I read something about a PRESSURE TANK application. AS i under stand it it is stank where you put your Finishing material in my case Water Poly. Then it forces the material to the gun. So you have 100% of stuff coming out.. Sort of like a Airless paint sprayer. Don’t want to buy a big arse high capacity compressor

Is that the way it works

Any experience using this one here?

Not sure about the tank to put your finish in, but you can add a tank to your compressor so it will hold more air volume and allow you to spray.

You can use a paint pressure pot or an air storage tank, BUT either will cause the small compressor to run continuously in order to maintain pressure, which it probably won’t. The pressure will be correct at the start, but as soon as the pressure drops, the compressor will switch on, but because it is small, it will not keep up with the required pressure. The CFM output of the compressor at the spraying pressure must match or exceed the CFM requirement of the spray gun.

Have your say...
