This Avantco 19386316 night curtain is a direct replacement for the one that came with your Avantco air curtain merchandiser. Use it to replace a worn or broken night curtain to ensure your unit is operating efficiently. This curtain reduces wasted energy and keeps food cold during overnight hours. It's designed to cover most of the front of your air curtain merchandiser so that you don't need to worry about cold air escaping during off hours, and it helps to make sure your food stays cold between shifts. It's compatible with Avantco HAC-63 and CAC-60 air curtain merchandisers.
