TEK Natural Ventilation Passive Stack

TEK’s natural ventilation passive stacks are available for roof mounting. They are available in any size and shape, square, rectangular, circular. The size is dictated by the air volume, pressure drop and the available footprint on the roof to be acceptable to the planning authority.

There is also a choice of construction featuring a choice of mitred corners or removable sides. A roof option of monopitch, pyramid or barn is offered too. These natural ventilation passive stacks can be mounted on flat or pitched roofs.

Passive stacks are used in conjunction with our wall vents and large roof units can operate utilising atrium voids and be set for summer or winter ventilation.

Construction

Manufactured from HE9TF extrusion with class A louvre profiles with triple water turnbacks and a choice of birdguard or insect mesh. The units are supplied fully assembled with one piece curb and water defence system and they are supplied complete with a fixing pack. Our new highly insulated damper is fitted and electrically operated to provide the correct air volume at a given velocity.

Internal insulated ductwork and grilles with removable cores are provided when specified.
