Tsurumi 80TRN417 Submersible Self-Aspirating Aerator – 80TRN417

The Tsurumi 80TRN417 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, it 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 throughout the tank, providing excellent oxygen transfer and powerful agitation for efficient biological treatment. The 17 kW motor delivers high-performance operation for large wastewater treatment systems. :contentReference[oaicite:0]{index=0}
