                Areas of application

                • They are used in many sectors in discontinuous and continuous operation in the three basic processes of extraction, leakage extraction and degasification, for example:
                  extracting dry gases, saturated gases and vapours
                  extracting contaminated gases
                  delivering liquid shares at a constant vacuum
                  delivering explosive gases, e.g. hydrogen
                • Oil-free compression, i.e. no oil in the medium nor in the exhaust air
                • Minimum suction pressures possible up to 33 mbar abs., with gas ejectors (also known simply as "ejectors") even possible up to 5 mbar abs.
