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.
An older catalogue of Elektror also lists RD 0, RE 0; the manufacturer's current product pages do not name these models.
About the series
Radial compressors by Elektror
An impeller turning at high speed throws the air outwards into the spiral housing and so builds up pressure – for very large flow rates at small pressure differences.
The RD comprises 21 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.
