Blow gun for air compressors

A blowgun is an air tool designed for use in many industrial applications where compressed air for cleaning purposes is used. Blowguns can be purchased with many tip configurations for many possible applications. However, the most important factor in choosing the right blowgun is SAFETY. Mostly it is common sense. You should always wear saftey glasses like you would with any other air tool. Safety includes the following considerations: PSI (force), noise level, and ergonomics. Safety Standards for PSI and noise level are outlined in the following US Department of Labor, OSHA Standards For General Industry Revision 1999:
Standard 1910.242(B) – Compressed air for cleaning purposes shall not exceed 30 pounds (13.5 kilograms) per square inch (6.5 square centimeters) when the nozzle end is obstructed or dead-ended, and then only with effective chip guarding and personal protective equipment.1
Standard 1910.95(a) – Protection against effects of occupational noise exposure shall be provided when the sound levels exceed those shown in Table G-16 of the Safety and Health Standards. Feasible engineering and/or administrative controls shall be utilized to keep exposure below the allowable limit.1
