EN-Seefire

Natural louvred ventilator designed for automatic smoke extraction, day-to-day ventilation and for daylight entry.

Overview

Certified according to EN 12101-2, ECO is a natural smoke and heat extract ventilator. The Seefire has been tested for permanent fall-through protection and has been classified according to EN 1873.

The Seefire can be adapted to all kinds of projects as the result of its wide range of product variants. The ventilator can allow the entry of natural daylight.

The Seefire has an ingenious drainage system and has proven its worth a thousand times over as a robust and durable natural smoke and heat ventilator.

The louvres of the Seefire are centrally pivoted, which, due to their own weight, open smoothly even when there is no voltage or pressure. Its features and benefits are evident: its control and operation are cost-effective and efficient.

Clever and robust construction

The Seefire louvres do not protrude above the body of the unit, which means that the ventilator can be operated even in windy conditions.

The ventilator is permanently fall-through proof whether it is open or closed. The relevant tests were carried out on a ventilator without any louvre infills, thus the fall-through protection is independent of ageing or wear of the respective infills.

Seefire is an automatic opening vent (AOV). To learn more about AOV systems, check out our AOV Systems page.
