Very powerful, industrial type hood. At the max setting, it takes few min to get rid of all indoor air. As it has a powerful fan, the unit is LOUD. After 7 years of use, lot of crud and polymerized oil had caked the blower wheels and blades that destroyed the motor bearing. So make sure to cleanup once a year. Now I need to replace the motor.
