Abstract

This study addresses the need for a comprehensive risk and impact assessment of compressed air (CA) and vacuum (VAC) systems across Boise State University’s campus, with the goal of improving system understanding, reliability, and future infrastructure planning. CA and VAC systems are critical to campus operations, supporting applications such as laboratory research, clean room production, and pneumatic controls for thermal comfort. Methods of evaluating risk and condition included on-site inspections and walkthroughs with facilities technicians, stakeholder meetings, and review of equipment documentation, including owner manuals and technical resources, to identify system configurations and common failure points.

The assessment evaluated 26 compressed air systems and 5 centralized vacuum systems supporting academic, research, and facilities operations. Key findings indicate that most campus systems rely on reciprocating compressors due to their suitability for high-pressure, low-volume pneumatic and shop air applications, as well as their relatively low cost and ease of maintenance. In contrast, scroll compressors are primarily used for lab or other specialty applications due to their increased reliability and fewer moving parts, though they typically require more specialized maintenance. System condition was found to vary widely, with several nearing or exceeding expected service life. Identified factors contributing to equipment condition scores include air leaks, moisture contamination from aging or undersized dryers, and mechanical wear in compressors and vacuum pumps, all of which contribute to reduced efficiency and increased risk of failure.

Overall, 3 systems were identified as posing increased risk to campus operations and are recommended for replacement or major repair. The study highlights the importance of lifecycle-based maintenance and strategic capital planning, emphasizing the need for targeted equipment replacement, improved system redundancy, and ongoing condition assessments. Implementing these recommendations will enhance system reliability, energy efficiency, and continuity of service across campus facilities.
