Dual Purpose Natural Ventilation & Smoke Ventilators

The Encon louvre is designed to combine the functions of a roof mounted natural extract ventilator and a heat and smoke exhaust ventilator. A multiplicity of control facilities are available.

The Encon louvre has an exceptionally low profile, with a large free area and maintains good aerodynamic properties.

Control systems can be designed to suit the requirements of Fire Officers, incorporating remote panels to over-ride the normal day to day function and to assist in fire fighting.

Encon louvres can be fitted in any plane - horizontal, vertical or sloping. In addition to their day to day ventilation function they also produce additional dalylight and the ventilator base is individually made to the characteristics of each roof or wall. Internal drainage channels carry water through opening slots in the base of the louvre. The louvre blades overlap in the closed position thereby ensuring virtually no air leakage and complete weather-proofing. Each louvre blade pivots on stainless steel pins running in nylon bearings.

Encon Louvres are available in a wide variety of sizes ranging from 1000 mm wide to 2000mm wide. The length is normally determined by the constraints of the building structure where it is to be fitted.

Encon louvres are normally manufactured in mill finish aluminium alloy to BS1470 NS4H3. At an extra cost they can be supplied in a variety of British Standard colour finishes. A high seal model is available conforming to BS4315 Part 1 BSDD4 incorporating a silicone treated brush pile strip which is applied to seal the small gaps between the moving parts of the louvre blades. Translucent louvre blades can also be supplied utilising krystalite double skinned material
