What's the smallest air gun I can use?

Q: What is the smallest air gun that would enable me to get down into tight spaces for cleaning?

A: From GuardAir, the air gun that has the smallest diameter for getting into hard-to-reach areas is the Blind Hole air gun. It has a 3/16" outer diameter brass extension with 1/8” outer diameter plastic stylus tip. These guns also come with the option of 6”, 12”, or 18” brass extension. They feature a 45-degree angle at the tip of extension to enable even greater access into those hard-to-reach areas.
