Technical Documentation Fahrtwind-Simulators Type Series VQF Functional Principle The compact LTG Fahrtwind-Simulators were specifically designed for use in roller type dynamometers. However, they are equally appropriate for general cooling or flow simulation applications. The tangential fan of the Fahrtwind-Simulator pulls in ambient air through an inlet protection screen. Among the versatile applications are e.g. the automotive industry as well as test labs for machine design and systems. The adjustment of the required air speed is done through a VFD. It can be done directly at the operator...
