SCOTT® Air-Pak® 75™ SCBA Backpack, Standard, High Pressure

Streamlined back frame provides a lower profile and allows greater freedom of movement. Weight distribution provides comfortable support. Reflective front patches enhance night visibility. Cam-over center slide accommodates 30-, 45- and 60-min. cylinders. An enhanced latching system allows quick cylinder changes. Parachute-style harness fasteners adjust smoothly but keep straps secure. The oversized fasteners are easy to work, even with gloved hands. A one-finger release disengages belt buckle.
The AirPak 75 SCBA Backpack provides two interconnected pressure reducers. Any reduction in primary pressure triggers an automatic transfer to the secondary circuit while a vibrating alarm alerts the user, allowing a timely exit from the hazardous area. A simplified central battery module holds six standard AA batteries in the housing. The control console contains a constant-on edge-lit light for the pressure gauge that comes on when the cylinder valve is opened. A photo-sensitive diode automatically dims and brightens the heads-up display as light conditions change. High pressure (4500 psi).
