Stairwell natural louvred ventilator

Stairwell is a low profile, roof or wall mounted louvred ventilator, 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 fire fighters. The ventilator can be installed vertically or horizontally in roof openings and can be used as a corridor ventilator.

It is suitable for installation at any angle from vertical to horizontal. It conforms to EN 12101-2 and is CE marked. It has an open area of at least 1.0m² in accordance with the requirements of Approved Document B to the Building Regulations and BS 5588.

Stairwell ventilators should be controlled by clearly visible manual switches 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.
