The C-Series claw pumps and compressors from Elmo Riestchle generate contact-free vacuum or compressed air efficiently and economically.  This is possible because of the principal of internal compression.  The gas is precompressed within the compressing chamber, then discharged.  This leads to an evident energy saving compared to rotary lobe blower designs without internal compression.
