Description
The Copeland APD165S (SKU 059144) is a precision-engineered APD Series pulsation dampener and discharge muffler designed to minimize compressor-generated noise and pressure pulsations in refrigeration and air conditioning systems. By absorbing and attenuating discharge line pulsations at the source, this muffler helps protect downstream components, reduce vibration-related wear, and improve overall system reliability.
