Natural ventilator for smoke control in a stairwell.
A louvred ventilator, installed onto a roof or into a wall, designed to provide heat and smoke exhaust ventilation in protected stairwells within residential apartments, hotels, shops and offices. It is principally applied to protect means of escape for occupants and to create a safe means of access for firefighters. The ventilator can be installed vertically or horizontally and can be used as a corridor ventilator.
It conforms to EN 12101-2 and is CE marked. It has an open area of at least 1.0 m² in accordance with the requirements of Approved Document B to the Building Regulations and BS 5588.
A stairwell ventilator should be controlled by a clearly visible manual switch at the top of the stairwell and close to the final exit from the stairwell. The optional break glass switch or fireman's override switch are recommended for this.
