Tsurumi 50TRN45.5 Submersible Self-Aspirating Aerator – 50TRN45.5

The Tsurumi 50TRN45.5 is a submersible self-aspirating aerator designed for efficient aeration and mixing in sewage and wastewater treatment applications. Featuring Tsurumi’s special semi-open impeller, it draws air directly from above the water surface without the need for a separate blower for standard aeration duties. The aspirated air is vigorously mixed with water into fine bubbles and discharged evenly around the aerator, delivering excellent oxygen transfer and powerful agitation throughout the 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 reliable performance, extended equipment life, and reduced maintenance in demanding wastewater treatment environments.
