Rational CM Parts for CombiMaster Ovens
The Rational CombiMaster, commonly identified by the abbreviation CM, is a professional combi oven series designed for cooking with hot air, steam and combined cooking modes.
CombiMaster ovens have been produced across different generations. This is important when searching for replacement parts because the meaning of a CM model can depend on its production period.
At Brooks Parts, you can find Rational spare parts for various CombiMaster generations.
Rational CM model references include:
- Rational CM 61 – 6 × GN 1/1
- Rational CM 101 – 10 × GN 1/1
