When safety is a priority

Airocle’s Y Series is the perfect natural ventilation solution for when fast ventilation from pressure relief may be required.

Y Series roof louvres are available in two models, the affordable, reliable and effective 240R model and the 360R model, which offers more stringent protection and is best used in potentially explosive situations.

The Y Series has been specifically designed by Airocle’s qualified and experienced engineers to be ‘green,’ efficient and fail-safe.

When the ventilator experiences a rise in pressure, it responds extremely quickly, allowing for the release of rapidly expanding heated gases. This mitigates the dangers of air pressure to a structure.

The ventilators, which may be used alone or with Y Series wall ventilators.
