Tsurumi 100TRN424 Submersible Self-Aspirating Aerator – 100TRN424

The Tsurumi 100TRN424 is a heavy-duty submersible self-aspirating aerator designed for efficient aeration and mixing in municipal and industrial wastewater treatment applications. Its special semi-open impeller creates negative pressure that draws air directly from above the water surface without requiring a separate blower for standard aeration duties. The aspirated air is thoroughly mixed with water into fine bubbles and discharged evenly around the aerator, delivering high oxygen transfer efficiency and powerful agitation throughout the treatment tank.

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 provide dependable performance, extended service life, and reduced maintenance. The 100TRN424 is ideal for large treatment facilities and can be installed in deeper tanks with an optional stand or draft tube. :contentReference[oaicite:0]{index=0}
