The Invisivent Air Basic pressure-controlled vent is characterised by good acoustics, achieved even when open. It works perfectly in its basic role, as a way to ensure fresh air indoors, mounted on the window profile. The advanced construction solutions of Invisivent Air Basic ensure that the air supply is steady, directed upwards and that no draughts are created, even in strong winds.
The Invisivent Comfort High pressure-controlled vent is another step towards maximum energy efficiency and protection against bothersome noise. It is distinguished by its replaceable acoustic foam, which is easy to keep spotlessly clean.
Invisivent Comfort High is a highly aesthetic solution that works exceptionally well in modern construction in large cities, where the priority is good ventilation without compromising on acoustic insulation.

The Invisivent Air Light is a thermally insulated window vent, fitted on the window profile, that self-regulates the air flow based on pressure differences inside and outside the building.
This is a solution that performs equally well in modern buildings and renovations due to its uniform, monoblock construction and discreet design. It also allows for the use of the optional Pollux PM10 filter, which eliminates harmful airborne particulate matter.
