The TRN-series are self-aspirating, submersible aerators. A built-in special semi-open impeller draws in air. This is mixed with the liquid and discharged at a high pressure leading to highly efficient aeration.
The BER-series are submersible ejectors comprising a B-series sewage pump and a venturi-jet pump. Air is drawn in by the self-aspirating mechanism and is discharged into the mixture through the diffuser. The powerful single jet current gives unrivaled vertical convection stirring.
The RS-series are rotary air blowers with three-blade rotors. The well-balanced rotors and innovative helical outlet ports minimizes impact and pulsation noise.
