The Sundström SR 700 / SR 900 Half Mask Pack with SR951 Hose is a unique, hybrid respiratory solution that bridges the gap
between traditional half masks and full-powered air systems. By pairing the
ultra-lightweight SR 700 Particle Fan Unit with the
professional-grade SR 900 Half Mask, this kit offers the elite
protection of a PAPR with the low-profile maneuverability of a half mask.
The "Positive Pressure" Half Mask Advantage:
This kit is a game-changer for workers who prefer the
compact fit of a half mask but want to eliminate "lung-power"
breathing. The SR 700 fan unit does the heavy lifting, pushing a constant
stream of filtered air through the SR 951 Single Hose and into
the mask. This creates a positive pressure environment that makes breathing
effortless and significantly reduces heat and moisture buildup inside the
facepiece.
