This ejector with an option for flow-rate regulation can be used for e.g. the exhaust of burnt gases or other waste gases. The ejector is suitable for pumping high-temperature burnt gases and also functions as a cooler of flowing gases.

A multifunctional unit for emission reduction is used to verify gas cleaning technologies, e.g. volatile organic compounds. The main advantage of the device is its wide spectrum of use, both in the laboratory and in practice under a variety of working conditions, in particular in heavy-chemical plants.
