Radial roof fan

The UKROS-DU/DUV roof fans are designed for removal of smoke and hot gases during fire conditions, ensuring safe evacuation and protection of structural elements. Their key feature is the upblast discharge system with foldable protective pockets, which provides an effective vertical exhaust of smoke away from the building.

Each fan is equipped with a new, improved impeller with backward-curved blades and a toroidal inlet cone with an enlarged diameter, enhancing airflow and efficiency. The impeller is directly mounted on the motor shaft, ensuring stability and smooth operation.

Fans are equipped with high-quality three-phase asynchronous single-speed motors, with the option of frequency control for adjustable rotation speed.

Available configurations:

• General-purpose industrial (N)

• Corrosion-resistant (CR1) — only for DUV mode

• Explosion-proof, corrosion-resistant (VCR1) — only for DUV mode
