Inlet Vane Control Dampers

DTL Inlet Vane Dampers (IVC) are predominantly installed in centrifugal fan inlets to provide regulation and control.

Its multiple blade arrangement around a central hub helps to introduce swirl into the fans inlet for an enhanced flow control.

DTL’s Inlet Vane Dampers can be fitted with any form of actuation allowing either local or remote modulating control and can also be designed to fulfil the requirements of Hazardous areas.

DTL Inlet Vane Control Dampers can be manufactured in Carbon Steel or Stainless steel, however for special applications we can utilise any material to suit your requirements.
