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.
Models marked FU or FUK run on a frequency converter; their figures apply at the manufacturer's rated frequency.
An older catalogue of Elektror also lists SE 4n, SE 42; the manufacturer's current product pages do not name these models.
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 SD/SE comprises 29 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.
We carry the vacuum pumps of the same family by Elektror as products: SD/SE series (vacuum operation).
All compressor series of our manufacturers by design: compressors by technology.
