Scott’s ACSi SCBA is designed for comfort, reliability and flexibility. Featuring the ACS™ (Advanced Carrying System), its back-plate is molded to fit the spine and back and its padded harness contributes to greater user comfort and reduced user-burden and fatigue. With its reliable two-stage pneumatic system, the ACSi is engineered for reliability and ease of use. Only a simple Scott® “quarter-turn” is needed to disengage the pneumatics from the back-plate and once removed, the back-plate is easy-to-clean for quick turn-around. The ACSi is NIOSH approved for use in non-fire related environments; a must have for your Industrial SCBA needs.
