Product DescriptionAn automatic booster fan designed to improve airflow delivery in longer ductwork for more effective heating or cooling in home or industrial settings. Features a highly intuitive differential pressure switch that senses changes in your ducting to automatically operate its on/off activation. It also allows for mounting in any direction, making it possible to direct airflow vertically, horizontally, or diagonally. The inline duct fan also features five speeds powered by PWM controls that can generate precise airflow levels. This, combined with its flexibility in installation, provides total ventilation control in extended ducting and other difficult-to-reach spaces.Automatic Pressure SensingThe fan pressure switch delivers automatic activation capabilities to boost your heating or cooling on-demand, eliminating the need for manual adjustments. This is achieved by detecting pressure change in your ducting and turning it on whenever your home appliance is on. The smart sensor also allows you to omnidirectionally mount the duct fan for enhanced airflow versatility in existing HVAC systems.Quiet and Energy Efficient DesignThe automatic duct fan features a next-gen EC m
