The OZA-PEK Roof Adapter is designed to form a uniform airflow velocity field before the fan impeller blades.
One side of the OZA-PEK adapter is attached to the inlet flange of the OZA or VKOP 0 fan casing, and the other side connects to the STAM roof curb.
Using the adapter ensures proper airflow distribution, stable fan operation, and reduced aerodynamic losses in roof-mounted ventilation systems.
