The right AirMax® Aeration System depends on your bin capacity, hopper design and whether you are equipping a new bin or retrofitting an existing one. Meridian offers one-piece vertical, sectional vertical and horizontal configurations for 40° and 45° hopper cones, with models for bins from 3,300 to 20,000 bushels.
One-piece vertical systems are designed for factory installation on new Meridian bins. Sectional vertical systems are available for retrofit and high-airflow applications. Horizontal systems feature a removable duct for easier cleaning and can be removed when an approved fertilizer-compatible bin is used for fertilizer storage.
