About this file
This is a Salient Characteristics document for an Emergency Breathing System procurement (Contract No. 70Z03826QE0000057). The system is intended for USCG aircrew use and must meet stringent specifications for operation in marine and saltwater environments.
The complete system assembly must be certified and fully functional to a minimum depth of 6 meters (20 feet), with a maximum charged weight not exceeding 3 lbs (1.36 kg). The system shall have no ON/OFF switch, knob, or manual isolation valve and must remain in an "always-on," pressurized, ready-to-breathe state once charged—a critical safety requirement to prevent aircrew members from inadvertently failing to activate the device during emergency egress. The cylinder must be constructed from seamless, high-strength aluminum with full anodization, contain a minimum internal volume of 1.5 cubic feet of compressed air, and be rated for 3000 PSI operating pressure. The cylinder and first-stage regulator assembly combined must not exceed 10 inches in length to fit the standard USCG Aircrew R/W vest emergency breathing bottle pocket. The first-stage regulator must be piston-type with 360-degree swivel capability, an integrated 0-3000 PSI dial pressure gauge, and an over-pressure relief safety plug. The second-stage regulator must feature a low-profile design with a swivel hose attachment and a rigid, injection-molded hard purge protection cover that completely shields the purge button to prevent accidental activation during storage, handling, or flight operations. The regulator diameter shall not exceed 2-1/4 inches with an overall length of 2-3/4 inches. The contractor must supply the system with two hose length options (20 and 27 inches) made from polyester outer braid with polyurethane core. Support requirements include customization capability, factory-certified overhaul and maintenance services, and comprehensive documentation demonstrating compliance with all physical dimensions, depth certifications, and the always-on architecture with purge protection integration.

Salient Characteristics Emergency Breathing System
1.0 Complete System Assembly
• Operating Depth: The complete assembly must be certified and fully functional down to a minimum depth of 6 meters (20 feet).
• Total Charged Weight: The maximum weight of the fully charged system (cylinder, regulators, hose, and manifold) shall not exceed 3 lbs (1.36 kg).
• Activation Mechanism:
o No ON/OFF Switch: The device SHALL NOT have an ON/OFF switch, knob, or manual isolation valve.
o Always-Ready State: The system must remain in an "always-on," pressurized, and ready-to-breathe state once the cylinder is charged. This is a critical safety requirement to eliminate the risk of an aircrew member failing to open a valve during an emergency egress, or the system being inadvertently turned off.
1.1. Cylinder Specifications
• Material: Seamless, high-strength aluminum construction.
• Finish: Fully anodized exterior surface for maximum corrosion resistance in marine and saltwater environments.
• Capacity: Minimum internal volume of 1.5 cubic feet of compressed air.
• Operating Pressure: Rated for a fill/charge pressure of 3000 PSI (207 BAR).
• Dimensional Limits: The overall length of the cylinder and first-stage regulator assembly must not exceed 10 inches (254 mm) to ensure proper fit and retention inside the standard USCG
Aircrew R/W vest emergency breathing bottle pocket.
1.2. First-Stage Regulator
• Design: Piston-type first-stage regulator.
• Range of Motion: Must feature a 360-degree swivel configuration to allow optimal hose routing and prevent kinking.
• Pressure Indicator: Integrated, easy-to-read dial pressure gauge indicating 0 to 3000 PSI (0 to
207 BAR).
• Safety Features: Equipped with an over-pressure relief safety plug.
1.3. Flexible Hose
• Material: Lightweight, high-flexibility outer braid made of polyester, containing a robust polyurethane core.
• Available Lengths: To accommodate various aircrew configurations and vest sizes, the contractor must offer the system with two distinct hose lengths:
o 20 inches (508 mm) o 27 inches (686 mm)

1.4. Second-Stage Regulator
• Profile: Low-profile design to minimize bulk and snag hazards on the survival vest.
• Swivel: Must feature a swivel attachment to the hose to ensure freedom of head movement.
• Purge Protection Cover:
o Design Requirement: The regulator must be configured with a rigid, injection-molded hard "Purge Protection Cover."
o Functional Requirement: The cover must completely shroud/protect the purge button so it cannot be depressed or activated during storage, handling, or routine flight operations.
o Justification: This design is critical to prevent the purge valve from being accidentally pressed against survival vest gear, which would lead to the inadvertent depletion of the compressed air supply.
o Dimensional Limit: The second-stage regulator, including the purge cover, shall not exceed a maximum circular diameter of 2-1/4 inches (57.15 mm) and an overall length of
2-3/4 inches (69.85 mm) to ensure compatibility and non-interference with the R/W survival vest.
2.0 Support Requirements
• The contractor must possess the capability to customize hose lengths or regulator configurations if operational needs change.
• The contractor must provide access to factory-certified overhaul and maintenance services for both the 1st and 2nd-stage regulators, in compliance with manufacturer-specified service intervals.
• Interested vendors must provide documentation demonstrating compliance with all physical dimensions (specifically fitting within the 10-inch cylinder pocket and the 2-1/4 inch regulator limit).
• Evidence of depth certifications down to 6 meters (20 feet).
• Confirmation of the "always-on" (no switch) architecture and the integration of the non-depleting
Purge Protection Cover.
