This is a brand new Whirlpool-made OEM FSP blower wheel (sometimes called a squirrel cage). It is used in full sized dryers made by Whirlpool including Sears Kenmore & Roper, among others.
If you are replacing your dryer's motor, you might need this wheel. The motor these dryers usually take is part# 279787 (or 3395654) which can be found in our store. We also have a complete rebuild kit for your dryer, it is part# 4392067 available in our store.
