About the series
Liquid ring compressors by Busch
An eccentrically mounted impeller forms a rotating ring with the operating liquid. The cells between the blades get smaller towards the pressure side and compress the gas – suitable for humid gases and gases containing vapour.
The DOLPHIN LN comprises 2 models; the table above gives for each model the data Busch publishes. We do not carry compressors as individual products – the models of this series are available from Ehrler & Beck on request, with advice on the selection, original spare parts and service.
We carry the vacuum pumps of the same family by Busch as products: DOLPHIN vacuum pumps.
All compressor series of our manufacturers by design: compressors by technology.
