    Roof-Mount Louvers

    These louvers are gravity operated. The blades open when your roof-mounted exhaust fan goes on and close when it's off, preventing backdrafts. The felt seal on the face of the blades ensures quiet closing and better protection from the weather.
    Also Available: Additional louver sizes. Please select 8061T999 and specify louver dimensions.

    Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. More economical than upblast roof-mount exhaust fans, these draw stagnant and humid air out through your roof and then direct it back toward the roof. All fans have a disconnect switch to turn off the power for servicing.
    Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.
    Brushless Motor—Fans with a brushless motor are more efficient than fans with a standard motor. They operate at a wide range of speeds for precise speed control and greater energy savings. They’re also quieter and have a longer lifespan because of their advanced electronic controls.

    Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. These exhaust fans draw stagnant and humid air out through your roof and then expel it up and away from the roof surface. All fans have a disconnect switch to turn off the power for servicing.
    Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.
    Brushless Motor—Fans with a brushless motor have advanced electronic controls that allow them to precisely operate at wide range of speeds, making them more efficient, quieter, and longer lasting than fans with a standard motor.
    Cannot Be Sold To—Fans that cannot be sold to the listed areas are restricted by energy efficiency requirements.

    Direct-Drive Exhaust Fans

    With fewer moving parts than belt-drive fans, these direct-drive exhaust fans require less maintenance. They have a built-in grease pan to collect waste while cooking. Mount these fans directly to your roof with the attached mounting brackets. They meet UL standards for ventilation in residential, commercial, and institutional kitchens.

    Belt-Drive Downdraft Roof-Mount Exhaust Fans

    Belt-drive fans are quieter and have a longer life span than direct-drive fans because components can be replaced if worn or damaged. More economical than upblast roof-mount exhaust fans, these draw stagnant and humid air out through your roof and then direct it back toward the roof.
    Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.

    All bases have a square bottom, round top, and flashing to simplify installation.
    To Order: For slope bases, please specify pitch: 1/12-11/12 in increments of 1/12. To determine pitch, use an angle indicator or divide rise by run (see illustration). For instance, if your roof rises 5" in 12" of horizontal space, your pitch is 5/12.
