Large volumes of high-velocity airflow is required for ventilating large and complex structures. Quickly removing smoke, engine exhaust, toxic gases or vapors from a large confined area increases safety of both personnel and property, reducing the chances of unexpected combustion, toxic inhalation, and general atmospheric danger. Used for ventilating: Malls Warehouses Factories Transportation Terminals High-Rise Building Stairwells & Lobbies When abnormal situations occur that require rapid ventilation to reduce airborne hazards, LSVs are mobilized to rapidly ventilate the space.
