ST003 Plastic Air Distributor is a high capacity 12 outlet plastic air manifold designed for medium to large scale fish farming operations that need to distribute airflow from a single air pump to 12 separate tanks or pond sections simultaneously. Non-toxic, durable and easy to install, the ST003 bridges the gap between the 10 outlet ST002 and the 16 outlet ST004, giving Nigerian fish farmers with medium to large multi-tank operations the perfect mid-large capacity air distribution solution.
