Bard part number 8000-863 is an OEM scroll compressor (ZR21K5-TFD-800) used in Bard wall-mounted air conditioners and related packaged equipment to pump and compress refrigerant through the refrigeration circuit. As the heart of the sealed system, this compressor is selected by Bard to match the unit’s capacity and electrical requirements, helping restore proper suction and discharge pressures when an original compressor has failed, is noisy, or is tripping on overload. Because compressor replacements are application-specific, confirm the exact Bard model and serial number or parts list before ordering, and plan on standard best practices like replacing the filter drier, verifying proper refrigerant type and charge, and checking airflow and system cleanliness to protect the new compressor at startup.
* Orders less than $50 may incure a minimum order fee.
