Greenheck's Vektor®-HS is a single-source lab exhaust system designed to reduce fan energy in demand based applications. It features Variable Geometry Nozzle (VGN) technology, which monitors changes in airflow and static pressure in the occupied space, causing the fan’s operation to adjust throughout the day based on demand. Featuring a compact, low-profile housing, the Vektor-HS has the benefit of lower horsepower, lower fan energy consumption and lower operating costs than traditional lab exhaust systems.

    Model Vektor-HS

    Utilizes the cost-effective belt-driven, tubular centrifugal fan with VGN technology to maintain constant discharge stack velocity regardless of laboratory exhaust airflow. As airflow through the fan varies, the variable nozzle automatically adjusts to maintain the specified discharge velocity. This belt-driven fan is available in single fan to triple fan systems. The Vektor-HS is ideal for use in a high school or university laboratory and commercial research facilities with lower airflow and pressure.
