Tsurumi 80TRN412 Submersible Self-Aspirating Aerator – 80TRN412

The Tsurumi 80TRN412 is a heavy-duty submersible self-aspirating aerator designed for aeration and mixing in municipal and industrial wastewater treatment applications. Utilizing Tsurumi's special semi-open impeller, the aerator draws air directly from above the water surface without requiring a separate blower for standard aeration. The aspirated air is vigorously mixed with water into fine bubbles and discharged evenly, providing high dissolved oxygen levels and powerful tank agitation for efficient biological treatment. :contentReference[oaicite:0]{index=0}

The 80TRN412 can also be installed in deeper tanks using an optional stand or draft tube. :contentReference[oaicite:1]{index=1}
