This Avantco 17814269 fan blade is a direct replacement for the one that came with your select Avantco SS-UC, SS-WT, SCL, or SCLM series refrigeration equipment. The condenser fan is an important part of your unit's refrigeration system, directing air into the condenser coil to help it dissipate heat. If the fan blade becomes damaged it's important to replace it and prevent potential harm to other key components, like the compressor.
