Direct Drive Propeller Roof Fan
Model LQ
Model LQ ventilators are direct drive propeller roof fans designed to deliver large volumes of air at high static pressure. LQ fans operate more quietly than conventional propeller roof ventilators and are recommended for applications requiring lower noise levels. The low silhouette of the LQ harmonizes with modern architectural design.

Performance certified is for installation Type A - Free inlet, Free outlet. Performance ratings include the effects of a birdscreen. The sound level ratings shown are loudness values in hemispherical sones at 1.5 m (5 ft) in a hemispherical free field calculated per AMCA Standard 301. Values shown are for Installation Type A: Free Inlet hemispherical sone levels. The brake horsepower capability of a fan motor is dependent of the degree of cooling the motor receives from the moving airstream over the motor. The above motor loadings do not overheat the motor and are within NEMA recommended limits. It is therefore not detrimental to the motor and is economically desirable.
