No longer in the range of Elmo Rietschle: C-DLR 60.
Elmo Rietschle no longer lists the sizes C-DLR 250, 300, 400 and 500 on its product pages or in the Product Guide 2026; the ATEX operating manual of 2024 still names them.
About the series
Claw compressors by Elmo Rietschle
Two claw rotors turn in opposite directions without touching each other. They trap the air, compress it inside the housing and push it out to the pressure side. There is no oil in the compression chamber, so the compressed air stays clean.
The C-DLR comprises 5 models; the table above gives for each model the data Elmo Rietschle 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 Elmo Rietschle as products: C series claw vacuum pumps.
All compressor series of our manufacturers by design: compressors by technology.
