Automatic Duct Fan with Differential Pressure Switch for HVAC Ventilation

Designed to enhance airflow delivery in longer ductwork, this automatic booster fan is an excellent choice for improving the efficiency of heating or cooling in home or industrial settings. The fan features a highly intuitive differential pressure switch that senses changes in your ducting, automatically activating the on/off function. This eliminates the need for manual adjustments, providing a convenient and efficient solution.

The inline duct fan's flexibility in installation allows for mounting in any direction, enabling you to direct the airflow vertically, horizontally, or diagonally. This versatility ensures optimal ventilation control in extended ducting and other hard-to-reach spaces.

Powered by a next-gen EC motor, the automatic duct fan delivers quiet and energy-efficient performance. The innovative motor is controlled using PWM technology, ensuring smooth operation while minimizing heat and noise levels. The fan's mixed flow design gives it a high static pressure rating, enhancing airflow in HVAC applications with restricted air movement, such as industrial settings like manufacturing and processing plants, as well as home residential settings like bathroom ventilation and central air and heating systems.

The duct fan features five speed levels, allowing you to precisely control the ventilation levels to suit your specific needs. This, combined with its flexibility in installation, provides total ventilation control in extended ducting and other difficult-to-reach spaces.
