Round Roof Element

The Round Roof Element BZL is designed for use in supply and exhaust ventilation systems for industrial, commercial, and public buildings. The element is installed directly onto the air duct and provides unrestricted air intake or exhaust above the roof surface.

A key feature of the BZL roof element is the absence of pressure loss. Due to its free-flow design, aerodynamic calculations are performed as for an open cross-section, simplifying system design and improving overall energy efficiency.

The BZL roof element is standardly manufactured from galvanized sheet steel, offering high resistance to corrosion and weather conditions. Upon request, the element can be powder-coated in any color according to the RAL chart to meet architectural requirements.
