Airbrush

Quick Tips

Noisy Compressor/Quiet Work Space – Many people who become involved with airbrush technique already own an air source.  In many instances, this is a compressor purchased from Sears or a hardware store for purposes other than spray painting.  Generally, since these were not designed specifically for airbrush technique, they can sometimes be too loud when operating in the work environment.  To eliminate the noise problem, some airbrushers enclose the compressor in an insulated box, which must have an opening that allows the compressor to breathe and possibly a fan to cool the compressor, as necessary. 

An easier way to solve this noise problem is to locate the compressor at a good distance and run an air line into the work area, where an air regulator is attached to the end of the hose.  The regulator, some of which come with a built-in moisture trap and airbrush holder, should be placed as close as possible to the airbrush station.  The airbrush hose is connected to the regulator and the other end is connected to the airbrush.  Because the regulator is close at hand, you can quickly and easily manipulate the air pressure. 

A tip would be to let the compressor run full-blast and do all air regulation at the work station.  You can also T-off the air at the compressor, thus allowing you to work with the power tools of original intent, i.e., nail gun, sander, etc.  See your retailer and visit www.silentaire.com for an extensive line of Silentaire Technology compressors.

MAC Valves – The new Hi-Line Airbrushes from Iwata look very similar to the older HP Series except for one unique feature:  There’s a knob situated at the bottom front of the airbrush just below the color cup. This is the micro air control or MAC valve.

A breakthrough in technology from IWATA, this valve allows infinite control of the air flow at the head assembly of the airbrush.  This is quite different from regulating the air pressure at the compressor.  For one thing, it allows you to adjust the airbrush to spray a coarse stippling effect by cutting down the air flow.  Conversely, by opening the air flow you will get full atomization without ever having to touch the regulator.  To achieve an extremely fine line for detail work, adjust the air valve to give maximum control of the paint output.  Also, by fully opening the MAC valve, the airbrush can be quickly cleaned during color changes.  To paint a broad background, fully open the valve to spray a large amount of paint. 

Some airbrushers find it handy to hold onto the MAC while painting, giving added stability and being able to instantly twist it open or closed at will.  See your retailer and visit www.iwata-medea.com.
