The effective ventilation throat of the triangular smoke ventilator is basically the same with the roof opening, which determines its ventilation performance to reach the ideal status, and realizes the high safety of the roof's natural ventilation.

The special form of the triangular smoke ventilator determines that it has good lighting and aesthetics and practicality. The starting angle of the electric opening can be set. The upper-opening triangular smoke vent skylights has better ventilation performance, and the downward-opening triangular smoke exhaust ventilator has better ventilation performance. The rainproof performance is better, and it can meet the requirements of ventilation and lighting for the roof of larger buildings when installed horizontally. The high efficiency of lighting and ventilation determines the high performance of the triangular smoke exhaust ventilator.
