Anyone knows Revell Alpha Compressor or Airbrush Revell?

Hello to everybody

I have a big problem with my airbrush.I bought it since 3 months and I haven't realized any more model since I have it.It has stopped me!:banghead::banghead:

It's a Revell Standard with a Revell Alpha Compressor(it has fixed pressure at 1 Bar).I am trying to use it but there isn't anything to do.I use acrylic Tamiya with Thinner and it spray only color for 5-6 seconds and then nothing!!!It's able to spray only the water.
I tried a lot of thing but it work very very badly!I don't know more what can I do!!

I don't know if it is a problem of fixed pressure and so the color can't exit well or a problem of airbrush

Is there anybody that knows this kind of compressor or airbrush and can suggest something to me?It's my first airbrush and I am not expert in these things.

In your opinion is better to buy a new compressor with pressure regulation(with my standard Revell airbrush),change airbrush with one at double action(with my comressor at 1 Bar) or change both my airbrush and compressor?

Thanks in advance for answer:smooch:

Hi,

Yes I know them. I know them very well.

To be short, forget that compressor and buy a powerful compressor from a hardware store, or any compressor that provide you with 3 Bar. You will need 1.5-2.5 Bar, depending on paint viscosity and temperature, to operate an external mix air brush (like Revell standard class). An internal mix air brush requires usually higher pressure. Sometimes it helps to replace the hose as stiff hoses create a sort of pressure drop, but do not expect too much improvement.

Basically the standard class air brush is suffiecient for automotive paint. They are cheap and easy to clean, in contrast to the sophesticated internal mix double action pistolees. Their maojr disadvantage is a higher consumption (better say despersion) of paint. In addition, they do not enable the user to fully control the spray. You can change the mixture ratio only but not the size of the spray. Therefore you will never be able to get the same fine surface finish that you get from internal mix pistoles. However, this is not a major issue because no pistole in the world will give you the appropriate finish, rather the sanding polishing you do after paint. Since you are going to polish anyway, it will not make great difference if you start polishing a rough or a slightly rough paint.

If you are going to use the air brush to paint one or two cars each year, do not invest in a compressor and use gas cans instead. They are not that comfortable to use as a compressor but they are useable, in contrast to that Alfa toy.

If you need further assistance and feel it is off topic write directly to me.

Good luck.
