Seefire natural louvred ventilator

Seefire is a natural louvred ventilator suitable for natural ventilation as well as smoke control. Seefire conforms to EN 12101-2 and is CE marked. It can provide inlet or extract ventilation as well as permit the entry of natural daylight for most kinds of industrial and commercial buildings.

The Seefire is popular with Specifiers and Contractors because of the wide range of options available, and Building Operators and Owners because of their simplicity and low maintenance.
