LVX vs LV4 fan size?

Postby kenc » Mon Nov 13, 2017 7:11 pm

Hi Hub,

I've had a silver cap in 1.4 for a long time very happy with it. Some time ago I bought a used orange cap gun in 1.3 with the thought of dedicating it to base and my silver to clear. Used the orange cap for the first time recently and was immediately disappointed with the fan size. I benchmarked the two guns at the same pressure swapping the caps back and forth. The silver cap gave a fan size of about 10-11 inches at a distance of just over 5 inches. The orange cap gave 8-9 inches under the same conditions. regardless of which gun they were on (one is a 1.4, the other a 1.3). Fan and fluid wide open on both guns, about 20psi at the gun trigger pulled.

Checked both guns are clean, no obstructions no obvious issues with the orifices on the orange cap.

The official Iwata blurb states 11.4" for silver and 12.2 for Orange. While I am on the money for the silver cap, the orange is way smaller.

What orange cap fan size should I expect?

I need the rest of the story. What material are you spraying, Is the base water or solvent? what is the spraying viscosity of both the base & clear And walk me through your set up procedure - are you controlling the inlet air pressure at the gun or the wall?

Hi Admin!

Metallic base coat, solvent based, Pressure set at the wall regulator while monitoring a gauge at the gun for 20psi with trigger pulled. 80 gallon 2 stage compressor, 18+ cfm, 3/8 id line.

But really regardless of spraying base or just plain reducer as a test liquid, the fan on the orange cap is 2" smaller than the fan on the silver cap regardless of me using the 1.3 or 1.4 LPH400.
All conditions are the same except for the cap. The only way I can see that the orange cap can spray a pattern that - according to Iwata marketing specs - is an inch WIDER than the silver cap is to spray from a couple inches further from the panel. Iwata specs say "no change in technique" for Orange over silver too.

thanks! :mrgreen:

Okay lets dig a little deeper :?: Would you mind checking the pattern SIZE & SHAPE with base coat using these setting - fan & material controls full open - inlet pressure 16psi at the gun with the trigger pulled to the full back position. At a measured 7 inches spray one vertical and one horizontal pattern- holding the horizontal pattern log enough till it runs. then post the results. ThankYou

As requested, 16psi at the inlet trigger pulled fully, 7" spray distance. Base coat w hardener. 1.3 tip.


Even resizing to 640x480 I get this message;

Sorry, "KENC" I am trying to get some help so you can up load the info We ask for IF, that fails would you be willing to send me the air cap and I will have our lab technicians see why the spray pattern is not up to par. If you agree let me know & I will send you shipping instructions.
