This <u>air brush set</u> is designed for both the amateur or professional artist. Used in school projects, workshops, professional paint shops, machine shops to spray oil, rust proofing, etc.– any job that requires a simple yet effective air brush that is <b>easy to maintain</b> and cheap. Starvin' Artist is an amazing custom picture framer that is also an art supply store in the Chicago area. The Model 250 is an easy-to-use, single-action, external mix air brush. The spray pattern can be adjusted from 3/4" to 2" by turning the paint tip. Because of the larger orifice (that's the opening that the paint comes out of), this unit will handle heavy viscosity liquid. Designed for larger overall coverage and not for fine work, the Model 250 will handle the majority of projects– fogging and blending, textures, patterns, etc. Packed as sets. The BA250-1 contains a spray gun with one 3/4 oz. jar attached, one additional 3/4 oz. jar, Propel regulator, a 6 ft. vinyl hose and instructions. The BA250-2 is the same as the BA250-1, but does not contain an extra jar. The BA250-3 contains all the items in BA250-1 plus a Propel can so you do not need to buy a compressor to use it right out of the box. This is a great cheap air brush.
