Depending on customer requirements a waste water aeration blower might possess various inlet duct configurations. The design parameters that usually vary are the inlet duct volume or the geometry of the duct. However, it is not yet well known how can the duct design influence the steady and unsteady compressor operation. Due to that, this work aims to experimentally check how do such parameters as inlet duct volume, inlet filter and inlet guide vanes position affect the compressor stable and unstable performance. The measurements results show that the influence exists and has mainly quantitative rather than qualitative character.
