The Challenge
The facility's dry-pipe fire sprinkler system depended on two fire protection compressors, including a 1993 C-Aire S175 baseplate unit that had been in continuous operation for 29 years. The original pump on the baseplate unit had reached end of life and required a full replacement. The facility expanded in 2019 with additional sprinkler coverage, adding the C-Aire S750 horizontal unit, and both compressors required strict code-compliant maintenance for resident safety.
The Solution
Installed a new pump on the 29-year-old baseplate unit, replacing the original that had served reliably since 1993. Installed a new belt and adjusted motor pulley depth and motor position for correct alignment and tension. Rewired the pressure switch for the new pump. Changed oil, air filters, and oil filters on both units. Inspected all electrical components across the system.
