EN12101-2 Certified

High-Volume Flap Ventilators

Engineered for heavy-duty smoke extraction and integrated daylighting. Certified snow-load ratings and fail-safe actuation for high-rise and industrial roofs.

Performance Metrics

Engineered for Extreme Loads

Every flap system is tested under rigorous thermal and wind conditions to guarantee fail-safe actuation when triggered.

SL 1000

Certified Snow Load

140°

Opening Angle

10k

Cycle Tested

Guaranteed opening under 100 kg/m² of winter accumulation.

Pneumatic or electric actuators maximize aerodynamic free area instantly.

Fail-safe mechanisms proven to maintain structural integrity over time.
