Firefighters rely on durable, reliable, life-saving equipment to do their job. The right gear in the field can mean the difference for a successful outcome. The ISI Rescuer RIC/RIT bag can supply emergency air to a downed firefighter or provide an instant refill in a hot zone. The AS1 Single is ISI’s mobile air supply. It’s designed to work with any cylinder and can have a second cylinder added to it without interrupting the air supply. ISI also offers test equipment so fire departments can be assured their equipment is on-call ready.
