As of October 2026, all values from the documents of Elektror. A dash means: not published by the manufacturer. Flow rate and motor power at 50 Hz and 60 Hz respectively, overpressure as the model's maximum.
Side channel and radial blowers state the pressure difference: it applies as overpressure in pressure operation and as vacuum in suction operation.
About the series
Side channel compressors by Elektror
An impeller accelerates the air, which circulates several times in the side channel and builds up pressure – oil-free and with little pulsation. For large flow rates at small pressure differences; most side channel blowers work either as compressors or as vacuum generators.
The 2SD comprises 9 models; the table above gives for each model the data Elektror 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.
All compressor series of our manufacturers by design: compressors by technology.
