Starting with the motor of the aerator, the end bell has been improved to alleviate pressure on the motor bearing. One of the main upgrades to the TT aerator has been the change to a stainless steel bearing support tube. This wider and larger tube eliminates the carbon support tube variation previously offered. Inside the tube, a shaft seal was added to ensure a more water-tight system. The new stainless tube allows the aerator to be used in both fresh and salt water.

Moving down the unit, the plastic insert of the lower bearing is now more substantial. Finally, at the base of the model TT transport aerator, which is submerged when in use, the aluminum alloy comprising the impeller has been upgraded which eliminates the need to specify the heavy stainless steel option.

While the previous TT transport aerator served users as intended, the feedback they provide and the desire to support a growing aquaculture industry was the impetus the engineers at Fresh-flo used to design the upgrades.

Hauling fish is a natural stressor for them with even a short-time transport of 10 to 30 minutes requiring conditions of constant air or oxygen supply. Even with ideal conditions, it’s possible to lose about a half percent of the fish. The quality of aerator placed in the haul tank dramatically affects the water quality and health of fish delivered. The model TT transport aerator is designed for tanks with 100 to 400-gallon capacity, and can be placed between two compartments to aerate both. With a standard pump capacity of 75 gallons per minute, a 45 GPM capacity can be specified for smaller fish. Fresh-flo transport aerators are used in every state and throughout the world so their dependability is proven.

Fresh-flo Corporation has been producing products for the aquaculture industry and private pond owners since 1958. In addition to transport aerators, they also manufacture pond aerators, two fish grader models, as well as a bug lite fish feeder.
