Ventilation chimneys

TPI-Polytechniek produces an extended program on ventilation chimneys; for air outlet as well as air inlet! These ventilation chimneys, like our air inlet valves produced out of high quality polyurethane, are developed for an optimum ventilation characteristic.


Chimney elements, with a wall thickness of 25 mm, are available in the diameters 315, 404,
430, 520, 560, 640, 720, 820, 920 and 1010 mm. The systems are supplied as half shells and have a length of 1meter. This assures not only the installation concept but for sure also the transport volume. Elements are simply and fast be put together by means of stainless steel tightening rings.


An extended list of parts and accessories makes that the systems can be used in practically all possible situation, requirements and circumstances. Consider here  for example adjustment flaps, butterfly valves, roof sheets, rain rings, rain caps etc.


Next to all standard available parts client-specific wishes can be fulfilled.
The high insulation value make the systems very much suitable for air inlet systems.
All polyurethane parts are available in the standard yellow colour as also in black.
