Description

Colt Labyrinth natural ventilator provides highly efficient ventilation in all weather. It utilises the natural buoyancy of warm air and requires no running costs. Labyrinth/5S is virtually maintenance free and is constructed from cold rolled, lightweight aluminium alloy. It has labyrinthine louvre blades that provide both continuous, rainproof ventilation. Each louvre blade is fitted with a rain channel that directs water to the side rain channels and onto the roof.


Features and benefits:

  • Efficient in operation, since it has a large free ventilation area, and it provides continuous ventilation in all weather.
  • Continuous, high efficiency and weathered natural extract ventilation.
  • Various fixing options: can be installed onto a roof to provide high level extract.
  • Easy to install: delivered to site in breakdown form or completely assembled for easy local assembly.
  • Minimal weight placed on the building - very low silhouette and low in weight. This means that less supporting steelwork is required than comparable ventilators. It is very well suited for retrofit, since the weight of the roofing panels removed can be around the same as the weight of the ventilator. Also suitable for places where there are strong winds.
  • Excellent light entry – view of the sky visible through the blades.
  • Durable: manufactured from tough, corrosion resistant aluminium, under the ISO 9001 quality standard.
  • Exhaustively tested for airflow performance and weather tightness.
  • Motorized louvre option - an optional shutter version is operated either pneumatically or electrically, and ensures that air leakage is kept to a minimum when ventilation is not required.
