  • Mobile Ventilation Unit MVU-48 Firefighting Equipment Tempest Blowers

    Mobile Ventilation Unit MVU-48

    The MVU® 48 is a slightly scaled down version of our MVU® 60, about 4,000 lbs lighter in fact but still provides massive air movement unlike any other ventilation unit with several customizable options available:
    • Massive 48" Seven Blade Aluminum Impeller
      The combined massive 48” (1.2 meters) seven (7) blade aluminum impeller and steel shroud are capable of generating air movement unlike any other ventilation unit around.
    • Massive Air Movement
      With its calculated 380,000 Open Air Flow CFM (645,624 m3/hr), the 48 is able to complete nearly any ventilation job in minutes, if not seconds; saving precious time, money, resources, and possibly even lives.
    • Hydraulic Powered
      Like the MVU® 60, all of the 48’s mechanical actions, including the fan’s blade rotation, are powered by a reliable hydraulic system. The hydraulic pressures are generated by its turbocharged Cummins Diesel engine, mounted under the MVU™'s silencer hood. Every MVU®-48 is custom built by Tempest’s team of engineers and fabricators.
    • Optional Features
      The MVU 60 proudly offers a number of options in addition to its standard features that are designed to help you overcome any unique challenges you may face in your specific application. From ventilator lift, the rotation, to a high volume water misting system, these options give you the power to pick and choose exactly what you need to ensure you’re properly equipped to ventilate effectively and efficiently.
    • Scissor Lift Option
      The optional Scissor Lift package allows the unit to be easily elevated on level ground to the height of up to nearly 10′ (3 meters). The lifting action is delivered through hydraulic pressures generated by the engine.
    • Ventilator Tilt Option
      Available with an optional Tilt Package which allows the ventilators to be directed either 30° up or down, greatly increasing the unit’s ability to ventilate elevated or lowered areas. Tilt controls are powered by the hydraulic pressure system.
    • Ventilator Rotation Option
      The ventilators can be rotated 380° continuously, in either direction with the Ventilator Rotation Option. The rotation action is powered by a 24V electric motor
    • Misting System Option
      Incredibly valuable in a number of scenarios such as hazmat, decontamination, and general cooling, the Misting System Option allows you to throw 87 GPM of water through 8 misting nozzles up to 130′ (40 meters) downstream from the ventilator.
    • Controls
      Unit controls are electronic and electronic over hydraulic by both fixed panel with controls and a wired or wireless remote control.
    • Unit Mounting
      Tempest offers a number of mounting options for the MVU®-48. Some platforms include custom tandem axle trailers, domestic and foreign commercial truck chassis, rail cars, hook-lift skid systems, and more. All of these mounts can be custom ordered and installed through Tempest.
