Tsurumi 50TRN42.2 Submersible Self-Aspirating Aerator – 50TRN42.2

The Tsurumi 50TRN42.2 is a submersible self-aspirating aerator engineered for efficient aeration and mixing in sewage and wastewater treatment systems. Equipped with Tsurumi's special semi-open impeller, it draws air directly from above the water surface without requiring a separate blower for standard aeration applications. The air and water are mixed into fine bubbles and discharged evenly, delivering excellent oxygen transfer while creating powerful agitation throughout the tank. :contentReference[oaicite:0]{index=0}
