Ejectors are simple devices, having no moving parts, which depend on the variation in the geometry of their internal passages for producing vacuum or creating compression.

Their simplicity accounts for the most reliable and maintenance free operation compared to the other mechanical vacuum producing devices. The simplicity of construction in turn puts a critical emphasis on the technology and aerodynamic design of these devices.

Ejectors utilize Pressurized fluids (Liquids or gases) as the Energy Input for driving the Ejectors.

The Ejector principle can be utilized on multiple ways for a vast range of applications.
