The Guardair Ultra QuietForce Air Gun with Fan Nozzle, No. U74FA, was specifically designed for when low noise matters. Operating the air gun with a typical 80 psig inlet pressure produces 77 dBA, consumes 22 scfm of air and generates 1.4 lbsf of output thrust -- making this gun low noise without compromising high performance. It incorporates an ergonomic design and is constructed of die-cast aluminum. The handle features an advanced composite, rubber grip, full-length trigger, and 3/8” FNPT inlet (1/4” FNPT also available with classic+ handle style). This air gun meets OSHA standards, is made in the U.S.A., and is ideal for the toughest cleaning jobs in the shop. In body shops specifically, the air guns are used to blow off automotive parts, such as a hood, after they have been sanded and prepped before painting.
