    High-Output Direct-Drive Duct Fans

    Image of Product. Front orientation. Duct Fans. High-Output Direct-Drive Duct Fans.
    Produce three times the airflow as standard direct-drive duct fans. All of these direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. Also known as axial duct fans, they install inline in ductwork for use as an exhaust, supply, or booster fan. All have a TEFC (totally enclosed fan cooled) motor enclosure, which can be used in dirty, dusty, and damp environments.
    Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.

    Belt-Drive Duct Fans

    Image of Product. Front orientation. Duct Fans. Belt-Drive Duct 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. Also known as axial duct fans, these install inline in ductwork for use as an exhaust, supply, or booster fan. All fans have a totally enclosed motor enclosure, which can be used in dirty, dusty, and damp environments.
    Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.

    Belt-Drive Hazardous Location Duct Fans

    Image of Product. Front orientation. Duct Fans. Belt-Drive Hazardous Location Duct Fans.
    These fans have an explosion-proof motor that is rated for hazardous environments. All are belt-drive fans that are quieter and have a longer life span than direct-drive fans because components can be replaced if worn or damaged. They install inline in ductwork for use as an exhaust, supply, or booster fan. UL and CSA standards apply to the motor.
    Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.
    IP56 Enclosure Rating— Fans rated IP56 have a motor enclosure that’s rated for protection in damp, dusty, and washdown environments.
