toroidal adapter

The OZA-PET Toroidal Adapter is designed to create a uniform airflow velocity field before the fan impeller blades. Using the adapter ensures stable operation and reduces aerodynamic losses.
The OZA-PET must be installed when the fan operates in discharge mode, as flanged inlet flow without the adapter leads to reduced airflow rate and pressure.
One side of the adapter is attached to the inlet flange of the OZA series axial fan casing, and the other side connects to a TUL, GMK, or REG damper.
