Dramm AME 400mm HAF Fan for horizontal air flow
The Dramm AME 400mm HAF Fan is designed to homogenize air by focusing on momentum rather than speed, helping reduce hot spots, stagnant pockets, and microclimates around the crop. By using lower air speeds and an aerodynamic, shrouded fan body, it can deliver more even air movement with fewer units—often lowering both energy use and installation cost. The shroud helps the fan throw air longer distances while also pulling air from behind, creating a consistent, stable circulation pattern through the space.
Energy-efficient greenhouse fan with variable speed control
The AME system pairs high-efficiency, long-lasting fans with variable speed regulation, so you can tune airflow as plants grow and conditions change. Typical operation is often set around 40–60% of maximum speed for steady circulation, with the option to increase airflow when canopy density rises or when climate conditions demand more movement. Many variable speed controllers can also integrate with climate control systems, allowing environmental inputs to automatically adjust fan speed for reliable, uniform airflow.
