Tsurumi 80TRN47.5 Submersible Self-Aspirating Aerator – 80TRN47.5

The Tsurumi 80TRN47.5 is a heavy-duty submersible self-aspirating aerator engineered for efficient aeration and mixing in municipal and industrial wastewater treatment applications. Its special semi-open impeller generates negative pressure to draw air directly from above the water surface, eliminating the need for a separate blower for standard aeration duties. The aspirated air is mixed with water into fine bubbles and discharged evenly around the aerator, providing high oxygen transfer efficiency and powerful agitation throughout the tank. :contentReference[oaicite:0]{index=0}

Designed for continuous-duty operation, the TRN series incorporates Tsurumi's exclusive Oil Lifter, dual silicon carbide mechanical seals, and an anti-wicking cable entry system to maximize reliability, extend service life, and minimize maintenance in demanding wastewater treatment environments. :contentReference[oaicite:1]{index=1}
