How a Coanda ejector works

A Coanda ejector is a purely geometric flow device, with no moving parts, that generates an induced flow using a high‑velocity primary fluid. The most common working fluids are air and steam.
The Coanda ejector (yellow) is coupled to an existing flow duct of a given diameter. Once the ejector is supplied with high‑velocity fluid, a low‑pressure region (red zone) is created and a secondary flow is rapidly entrained and accelerated.

Key Coanda ejector characteristics

Coanda ejectors are defined by two main overall dimensions, three geometric control parameters and two thermodynamic supply parameters (pressure and temperature). These variables are adjusted to match specific flow conditions and customer requirements.
Compared to a conventional fan or blower, a Coanda ejector is a more complex flow device. Its performance is tuned through careful optimization of geometry, supply pressure and temperature.
The inlet temperature has a significant impact on efficiency, so the overall performance depends strongly on the local operating conditions at the customer’s site.
