Aerox heavy industry ventilator

The Aerox louvred ventilator suited for highly efficient weathered natural ventilation and smoke control. It is particularly suitable for use in heat-intensive and noisy industrial buildings where there is a premium on available roof space
for such equipment.

It has labyrinthine louvre blades that provide both continuous, rainproof ventilation. It is lightweight, simple to maintain and install, and has a wide variety of ventilator options. It is suitable for day to day and smoke control natural extract ventilation. It has been tested and certified as a smoke ventilator to EN 12101-2 and is CE marked.

  • Dual purpose - Aerox is classed as a dual purpose ventilator, providing both day to day and smoke control ventilation. It is generally installed onto roofs providing high level extract.
  • Many options - Either pneumatic or electric controls are available. Acoustic attenuators can be fitted underneath the unit. A 4-sided baffle can be fitted for enhanced performance.
  • Aerodynamically efficient– Aerox’s shape means that it makes excellent use of natural air currents and so it is highly aerodynamically efficient.
  • Weather resistant - When the weather is changeable or rainy, Aerox can remain open without risk of rain entry, because in this instance the shutter blades are moved to an opening angle of 45°. To ensure that no rain can enter the building, there is an elaborate system of louvres within the unit. Any droplets that come in past the shutter blades are collected and discharged to the outside.
  • Easy to install – Depending on its size, Aerox can be delivered fully assembled to site. It has a wide range of base profiles to suit most sheeting, curb or other applications.
  • Relatively small footprint – because of its exceptionally high efficiency, it requires a relatively small roof area to achieve a high volume flow rate.
  • Durable - Aerox is manufactured from tough, corrosion resistant aluminium with stainless steel movable components.
  • Certified performance - Aerox has been exhaustively tested and certified to EN 12101-2: 2003 in accredited third party test laboratories and is CE marked.
  • Quality of manufacture - Aerox is manufactured under the ISO 9001 quality standard.
  • Design service - Colt provides a pre-order design service. Please contact Colt for more information relating to the application, specification, installation or servicing of Aerox.
Labyrinth low profile natural extract ventilator

Labyrinth provides continuous extract or inlet ventilation for most kinds of industrial buildings, providing high volume ventilation. It has aerodynamically designed louvers to provide continuous weatherproof ventilation. The unit can be used for air extract and air inlet and can be adapted to accept sound absorbers.

  • Efficient and weather resistant - Labyrinth is efficient in operation, since it has a large free ventilation area, and it provides continuous ventilation in all weather.
  • Various fixing options - Labyrinth can be installed onto a roof to provide high level extract.
  • Easy to install - Labyrinth is delivered to site in breakdown form or completely assembled  for easy local assembly.
  • Minimal weight placed on the building - Labyrinth is very low silhouette and low in weight and 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. It is also suitable for places where there are strong winds.
  • Excellent light entry – view of the sky visible through the blades
  • Durable - Labyrinth is manufactured from tough, corrosion resistant aluminium. It is manufactured under the ISO 9001 quality standard.
  • Exhaustively tested – Labyrinth has undergone extensive testing for airflow performance and weather tightness.
  • Motorised 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.
  • We are at your service - We provide a pre-order design service. We also offer complete project management, installation, wiring and commissioning, which means that we take complete responsibility to ensure that the product is in full working order within one package of works.

MoffittVent tulip-style natural extract ventilator

MoffittVent provides continuous extract ventilation for most kinds of industrial buildings, providing high volume ventilation. It is aerodynamically designed to provide continuous weatherproof ventilation. The unit can be adapted to accept sound absorbers.

  • Efficient - MoffittVent is efficient in operation and provides continuous ventilation in all weather. It has 100% free area to face area ratio. The ventilator is not affected by the direction or velocity of the wind - in fact its performance will increase in higher wind conditions.
  • Weather resistant– The ventilator’s design will not allow water entry into the building at any wind velocity. All water is collected by integral drain gutters and downspouts and re-directed out to the roof.
  • The ventilator has been designed to withstand wind speeds as high as 130 MPH and can be easily designed for higher wind speeds if required.
  • Optional damper – An optional manual or motorized damper ensures that air leakage is kept to a minimum when ventilation is not required.
  • Various fixing options - MoffittVent can be installed onto most kinds of roofs, either at the peak, down slope or flat.
  • Easy to install - MoffittVent is delivered to site in breakdown form for easy local assembly.
  • Durable - MoffittVent is manufactured from tough, corrosion resistant materials.
  • Low in maintenance – MoffittVent requires virtually no maintenance.
  • Design service- Colt provides a pre-order design service. Please contact Colt for more information relating to the application, specification, installation or servicing of MoffittVent systems.
Sandtrap louvred ventilator

Sandtrap is a sand trapping louvred ventilator for use in desert areas. It separates the sand from the incoming air by arresting the forward momentum of the sand. Because of the panel's configuration, additional filters are not required, and having no moving parts, it is virtually maintenance free.

  • Simple - no moving parts and no maintenance required.
  • Durable - Sandtrap is manufactured from tough, corrosion resistant aluminium alloy or stainless teel.
  • Certified performance - Third party tested for sand elimination effectiveness and pressure drop characteristics.
  • Design service - Colt provides a pre-order design service. Please contact Colt for more information relating to the application, specification, installation or servicing of Sandtrap systems.
Universal Louvre fixed external metal louvre system

Colt Universal Louvre is a versatile fixed louvre system providing either screening and/or rain defence in a wide variety of product options, materials and finishes.

  • Generic types - Colt Universal Louvre is a roll-formed or extruded single (1UL), double (2UL) or triple (3UL) bank system, used for screening and/or ventilation. It is very often used as plant room louvre, or indeed anywhere where plant needs to be covered up
  • Highly aerodynamically efficient – this reduces air resistance, allowing the plant and the aperture to be minimised thereby saving running costs.
  • Enhanced rain defence performance - 2UL and 3UL versions have a remarkably high resistance to weather.
  • Durable and maintenance free – UL is completely made from corrosion resistant materials which include aluminium and stainless steel.
  • Thermal expansion of the louvres enabled – the louvres are clipped and not riveted or screwed to structural supporting mullions.
  • Proven performance - UL has been tested to EN 13030:2001.
  • Easy to install – UL can either be delivered to site pre-assembled or as a kit of parts.
  • A wide range of options - it is available in various shapes, configurations, materials, finishes and coatings to meet the requirements of almost any project. 
  • Design service- Colt provides a pre-order design service. Please contact Colt for more information relating to the application, specification, installation or servicing of Universal Louvre systems.
