The VS-type jet fan is an axial impulse ventilation unit for forced airflow and smoke extraction in road tunnels, underground parking garages and other enclosed traffic spaces. Instead of relying on extensive ductwork, jet fans of this type are mounted under the ceiling and generate a directed air jet that pushes fresh air through the structure and drives smoke toward extraction points during a fire event.
This makes them a core component of modern longitudinal ventilation schemes, reducing construction cost compared with fully ducted systems. The VS series is aimed at tunnel operators, parking facility developers, ventilation contractors and engineering firms specifying smoke control systems.
Units are priced from $900 with a minimum order of two, making the series accessible both for new construction projects and for staged retrofits of existing garages where air quality and fire safety performance need to be brought up to current requirements.
