Airbrushing 101 - Part 2

In part two of Airbrushing 101 were going to continue looking at the Equipment involved more specifically the Air and how you get it to your airbrush.
There are a few different tools to use for air to push the paint out of your airbrush while all end up being expensive I will explain what they are how they work and what it means for cost.

Canned Air - Exactly what it sounds like, this is a can of compressed air that you can connect to your airbrush. This starts out as a low investment at 6-10 bucks a can for the larger cans but over time this will add up quite quickly. This method also comes with the problem of pressure not being consistent. This is due to not just the can losing pressure but also because as the air comes out it causes the can to get extremely cold and thus the can loses internal pressure.

Compressor - This is a large subject and there are multiple things to consider when looking at compressors.
Tank vs. No Tank - A compressor without a tank is going to be running the entire time you use it constantly working to get the air flowing. This can be a bad thing it will cause the compressor to always be warm thus generating moisture more consistently. Also this constant working means that the machine is pulsing air opposed to streaming air. That constant pulse can show up on your work under the right (or wrong) conditions thus your paint flow wont be as consistent as it could be. There is a plus however, a compressor without a tank is generally quite less expensive. Having a Tank eliminates most of the problems you can have that I mentioned the airflow will be more consistent and because of less heat being generated there is less of a build up of moisture, which is an issue that we will tackle another time.Noise - This is a huge issue for some people and for others its not a big deal at all. This is really going to end up being a cost related problem. You can buy a large powerful compressor
from your local do it yourself store (Home Depot and the such) for cheaper than $100 and have far more power than you will ever need but if you live with anyone else or in an apartment they will be far too loud for that environment. As soon as you move to a quite style compressor you will probably double the price for something with far less power and with no tank or any extra bits but it will be use able in the home.

I will be ending with that for today, there are many other things to consider for everything we have covered so far and I plan on going into detail about each part.
Next up will be what to consider with paint.
