EXAIR's Precision Safety Air Guns are extremely lightweight and have a focused blast of air that provides excellent cleaning capability. Our small diameter Atto, Pico, and Nano Super AIr Nozzles and extension easily fit into tight spaces while still packing a strong punch. These models include a Chip Shield to prevent chip blowback toward the operator. Precision Safety Air guns minimize compressed air use, maintain OSHA pressure standard 1910.242(b) and reduce noise exposure by remaining under OSHA standard 29 CFR 1910.95(a) decibel limits.
