About this file
This is a preventive maintenance service report for a dental air compressor system at the VA Medical Center in Erie, Pennsylvania. The document records the inspection and testing of a RAMVAC dental air duplex system (Model OSP25, Serial #4773030) performed on December 11, 2024, by technician RG/TP. The system, manufactured on July 1, 2019, is located in the dental mechanical room and operates two Gast OF1202 compressor units (Item #004822 each).
The inspection findings indicate that all major components evaluated—including discharge check valves, unloaders and solenoids, inlet filters, after cooler drain valves, rider and piston rings, and starter contacts—were rated as "Acceptable" across both pump units. Motor testing recorded voltage readings of 208V across all three phase combinations and amperage readings ranging from 9.30 to 9.70 AMPS across Motor #1 and Motor #2, with the system operating at 1,650 RPM. The CO monitor showed no manufacturer/model information available, and the dew point monitor similarly had no data recorded. The lead pressure switch was set to 80-100 psi with local lag alarm capability (audible and visual indicators). The report notes that the customer has installed an additional compressor system and is currently servicing dental units due to patient backlog. No parts were used during this service visit, and no specific deficiencies or recommendations were documented in the respective sections.
