Mobile Ventilation Unit

The Tempest MVU® 48 & 60 both operate through the use of a highly efficient and effective hydraulic system. This hydraulic system makes these units ideal for long operating times and frequent use. Powered by the legendary turbo charged Cummins® diesel engine mounted separately from the actual fan, hydraulic pressures are generated to operate the unit’s Tilt-Turn system (optional feature)Scissor Lift (optional feature), and impeller rotation. Due to the fan’s significant size and power, the 48 & 60 generate the highest CFM possible in a mobile ventilation unit. These two MVU® models are the power-houses in ventilation.

 

MVU 48: 380,000 CFM nominal open airflow
MVU 60: 400,000 CFM nominal open airflow
Whether you’re looking to ventilate CO from a mile-long tunnel, remove toxic fumes from a 50,000 sq. ft. warehouse or keep an outdoor work area free from particulates, the MVU® 48 & 60 deliver the air movement you need.

  • Mobile Ventilation Unit MVU-60 Firefighting Equipment Tempest Blowers

    Mobile Ventilation Unit MVU-60

    The powerhouse in our mobile ventilation line, the MVU® 60 is one of the largest units we manufacture and provides massive air movement unlike any other ventilation unit with several customizable options available.
    • Massive 60" Seven Blade Aluminum Impeller
      The combined massive 60” (1.5 meters) seven (7) blade aluminum impeller and steel shroud are capable of generating air movement unlike any other ventilation unit around.
    • Massive Air Movement
      At a calculated 400,000 Open Air Flow CFM (679,000 m3/hr), the mobile ventilation unit 60 will ventilate nearly anything caught downwind from it.
    • Hydraulic Powered
      All of the unit’s mechanical actions, including the fan’s blade rotation, are powered by its extremely reliable hydraulic system. The hydraulic pressure is generated by the legendary Cummins Diesel engine, mounted under the MVU®s silencer hood.
    • 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 to 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® 60. 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.

  • 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.
