This Avantco 19351124 condenser fan blade is a perfect replacement for the part that came standard on for select BC, BCT and BCR model refrigerated bakery cases. It is a vital part of your unit's refrigeration system, working to help your unit dissipate heat and keep the cabinet set to the right temperature. A broken or malfunctioning fan blade can prevent your unit from maintaining specifications and cause strain on other components, so be sure to fix it promptly.
