    Proportional HVAC Duct Damper Actuators

    Image of Product. Front orientation. Duct Damper Actuators. Proportional HVAC Duct Damper Actuators.
    This actuator provides better control than incremental actuators because it is constantly being positioned in response to duct airflow requirements. Use to automatically adjust dampers to regulate airflow. It attaches to the damper shaft to rotate it open and closed when signaled by a controller (not included). Actuator can be set to return the damper to an open or closed position if the power fails. Use the crank for precise adjustments.

    Light Duty Direct-Drive Wall-Mount Exhaust Fans with Louvers

    These light duty fans are designed for use without duct. They come complete with a movable-blade louver. The louvers are gravity operated so they open only when air flows through them, which prevents backdrafts. Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. Use these fans to draw stagnant and humid air out of a room or area. All have a totally enclosed motor enclosure, which can be used in dirty, dusty, and damp environments.

    Belt-Drive Wall-Mount Exhaust Fans with Louvers

    Image of Product. Front orientation. Exhaust Fans. Belt-Drive Wall-Mount Exhaust Fans with Louvers .
    These fans come complete with a movable-blade louver. The louvers are gravity operated so they open only when air flows through them, which prevents backdrafts. Belt-drive fans are quieter and have a longer life span than direct-drive fans because components can be replaced if worn or damaged. Use these fans to draw stagnant and humid air out of a room or area.
    120V AC, Single Phase (Hardwire)—Open Dripproof (ODP) Motor Enclosure

    Corrosion-Resistant Direct-Drive Wall-Mount Exhaust Fans with Louvers

    Rust won't be a problem with the durable plastic housing and louvers on these fans. The fans come complete with a movable-blade louver. The louvers are gravity operated so they open only when air flows through them, which prevents backdrafts. Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. Use these fans to draw stagnant and humid air out of a room or area. All have a totally enclosed motor enclosure, which can be used in dirty, dusty, and damp environments.

    These fans come complete with a movable-blade louver. The louvers are gravity operated so they open only when air flows through them, which prevents backdrafts. Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. Use these fans to draw stagnant and humid air out of a room or area. All have an open dripproof (ODP) motor enclosure for relatively clean, dry, indoor locations. They also have a wire mesh inlet guard to protect the fan from debris.
