Double fan ducting is a ventilation or airflow system that incorporates two fans to enhance air movement through ductwork. This setup is often used in environments where higher airflow, improved pressure control, or redundancy is required—such as server rooms, industrial workshops, HVAC systems, or exhaust setups. The fans can be arranged in parallel (to increase volume flow) or series (to increase pressure), depending on system design needs. Properly designed double fan ducting improves efficiency, reduces hotspots, and ensures balanced air distribution across large or complex spaces.
