With the Air-Pak NxG7, Scott has taken the traditional SCBA used in the fire service to the next level. Inspired by our customers, the patented snap-change quick cylinder change out eliminates the high-pressure hose and the CGA coupling that is found on other SCBA. This makes cylinder change out a snap. The waist-mounted pressure reducer still maintains the dual redundant system that is used on the Air-Pak 75, but its location improves the weight management of the complete Air-Pak by shifting it to the hips rather than the shoulders. The elimination of the high-pressure hose improves hose management of the Air-Pak SCBA and reduces potential snag hazards.
