Mobile Ventilation Unit (MVU®)

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: 130,000 CFM (221,000 m3/hr) nominal airflow
MVU 60: 150,000 CFM (255,000 m3/hr) nominal 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.
