    The C-Aire S275 represents our commitment to enhancing the fire protection industry through customer feedback, new technology, and industry trends. Experience the perfect balance of performance, reliability, and quiet operation for your fire protection needs. According to NFPA 13, air compressors with a flow greater than 5.5 CFM at 10 psi require a tank and regulator-style air maintenance device with a bypass and restrictor (NFPA 13 8.2.6.6). C-Aire still recommends an air maintenance device for air compressors with an airflow of less than 5.5 CFM at 10 psi, except when the compressor has a U switch or digital pressure switch installed.
