Description
The Copeland 061042 (Model APD167SB) is a professional-grade APD Pulsation Dampener/Muffler engineered to reduce refrigerant line noise and pressure pulsations in commercial and industrial refrigeration and HVAC systems. Its internal baffle design effectively absorbs compressor-generated pressure waves, protecting downstream components and contributing to quieter, more stable system operation.
