Application & Installation Notes
Designed for installation on the suction line upstream of the compressor, the STAS4811SV helps prevent compressor damage caused by moisture, acid, and particulate contamination — especially critical during system changeouts, burnout cleanups, or new installations. The shell-and-core design allows technicians to select and replace the desiccant core independently, reducing long-term maintenance costs. Always braze connections using nitrogen purge procedures and follow Copeland installation guidelines for best results.
