Rotajector Ejector

Mazda’s Rotajector delivers the best of both worlds — the simplicity of a steam jet ejector and the efficiency of a rotating vacuum system.
Designed for demanding industrial applications, it ensures high reliability, low maintenance, and superior energy savings.

Rotajector Ejector​

Hybrid technology that merges ejector design with rotary operation.
Engineered for consistent vacuum generation, reduced energy use, and long service life.

Product Overview

Mazda’s Rotajector is a unique hybrid vacuum system that integrates the operating principle of a steam jet ejector with a rotating assembly. This innovation provides the high suction capacity and reliability of traditional ejectors, while improving efficiency and reducing steam consumption through rotary assistance. The result is a compact, durable, and economical system suited for industries that demand continuous, dependable vacuum performance. With fewer moving parts than conventional rotary equipment and lower steam usage than ejectors alone, the Rotajector offers the perfect balance between simplicity, efficiency, and reliability.

Advantages

  • Hybrid design combining ejector and rotary technology
  • Reduced steam consumption and improved efficiency
  • High suction capacity with stable operation
  • Compact, rugged, and long-lasting construction
  • Low maintenance with fewer moving parts
  • Suitable for continuous duty in harsh environments

The Rotajector operates by using steam expansion in a jet nozzle to entrain process gases, similar to a standard ejector. However, instead of relying solely on static compression, a rotating assembly assists in further compressing and discharging the gases. This synergy reduces the overall motive steam requirement, enhances energy efficiency, and provides smoother operation compared to standalone systems.
