About this file
This document contains technical connection diagrams for a high-pressure pneumatic system upgrade at a facility with SCBA maintenance capabilities. The diagrams illustrate the current system configuration and the proposed replacement design for pneumatic equipment used to support Self-Contained Breathing Apparatus (SCBA) maintenance operations.
The current system (Enclosure 1) operates with two existing High-Pressure Air Compressors (HPACs) each rated at a maximum of 6,000 psig, feeding into four existing cylinders—two cylinders rated for 5,000 psig systems and two cylinders rated for 3,000 psig systems. The system includes pressure regulation at 5,500 psig for the SCBA maintenance room and 3,500 psig for the pneumatic room, with an out-of-service pressure sensor and relief/needle valves. The proposed replacement design (Enclosure 2) upgrades the four existing cylinders to new 6,000 psig-rated cylinders across all four positions, maintains the same dual HPAC configuration, and introduces a new regulatory structure with a relief valve, a regulator set to 4,000 psig, and adjusted pressure settings of 3,150 to 3,450 psig for the pneumatic room. The replacement includes a pressure gauge scaled 0 to 10,000 psig and reinstates functional pressure monitoring for the system while improving overall system capacity and pressure management capabilities.
