This Avantco Ice compressor serves as a direct replacement for the one that comes standard with select Avantco MC and KMC ice machines. It is designed to use R-290 refrigerant and swaps out quickly with the compressor in your unit to minimize downtime. This item includes starter components. A broken or malfunctioning compressor can prevent your unit from maintaining specifications and cause strain on other components, so be sure to replace it promptly.
