WCO natural louvred ventilator

WCO can provide extract ventilation as well as allow the entry of natural daylight for most kinds of industrial and commercial buildings. WCO is predominantly a Climate Control product, as it’s top section provides maximum ventilation. WCO can also be used for emergency smoke extract ventilation, although it is not certified as a smoke ventilator. Two controllable side dampers provide day-to-day ventilation when it is raining.

Features and benefits

A wide range of applications - WCO can provide both day to day and smoke control ventilation, although it is not certified as a smoke ventilator.

Polycarbonate versions allow the entry of natural daylight. There are pneumatic, electric or hand controls and a wide range of louvre types, accessories and finishes.

Various control options - The pneumatic control can be extended to incorporate a rain sensor, so that when it rains the top louvres automatically close and simultaneously the side louvres open. If used as a smoke ventilator, activation is either by a local thermal fuse which opens the unit at a pre-selected temperature, or by the controls responding to an external release signal. (Please note that it is not certified as a smoke ventilator to EN 12101-2).
