Ventillation devices ensure effective air circulation inside the building, even if all windows are tightly closed. Variety of ventilators available on the market allows all customers to tailor the best solution to their individual needs.

Ventilators are mounted in the upper part of windows. Outer air flows above people’s heads and do not cause an inconvenient draughts.

We may distinguish following types of ventilators based on operational style:

  • ventilators controlled by humidity sensors – are controlled automatically, the amount of delivered air depends on the room’s humidity. Higher humidity requires additional air flows. As a result, the amount of inflowing air changes during the day. Humidity sensor consists of several polyamide tapes. There is always a possibility to close the screen and restrict the air flow to minimum.
  • pressure ventilators – self-controlled ventilators, the amount of inflowing air depends on air-pressure differences inside and outside a building. This self-adjustment will continue until air-pressure differences reach the optimum level allowing to take advantage of ventilator’s maximum efficiency. Should these air-pressure differences increase to larger extent, the device’s wing will bend to restrict the amount of inflowing air, e.g. in the case of strong wind blows. There is always a possibility to close ventilator’s valve and reduce the amount of air flow to minimum.
  • manual ventilators – customers individually adjust the amount of inflowing air by opening/closing the valve.


Inefficient ventilation may cause:

  • water vapour condensation on window panes;
  • humidity in the building which may also trigger the development of mildew and mould;
  • bad mood (headaches, upper respiratory tract infections etc.);
  • unpleasant smell;
  • condensation of toxic pollutants radiated by furniture and finishing materials;
  • shortfall of air supply necessary to combust fuel in gas boilers, fireplaces etc.

Ventilation devices designed especially for PVC, wooden and aluminium windows.

Made of aluminium profile with PVC covers.

All devices come with a standard mosquito net.

Colours: white RAL 9010 (non-standard RAL colours are available on request).

Assembly type: fitted into the frame or into the rebate of frame and sash.

Operational method: pressurized ventilation.

TC60                                                    Invisivent EVO



Ventilation device designed especially for PVC, wooden and aluminium windows.

Made of aluminium profile.

Fitted with a thermal break.

Designed for direct assembly on a pane (on the 20, 24 and 28mm set).

Colour: available are all RAL colours and bi-colours.

Manual control through the blind’s string or a line.

The pane panel will be shortened only by 60 mm (assembly height: 60mm, total height: 74mm).

- Installation on top of the window frame

The Invisivent® EVO is a thermally broken window ventilator that is installed on top of the aluminium, timber or PVC window frame. This almost invisible installation guarantees maximum light penetration as the glass size is not reduced.

- Thermally broken

No cold air transfer from outside to inside.

- i-Flux®

Thanks to its self-regulating flap, the Invisivent® EVO ensures the supply of fresh and healthy air without draughts. Moreover, the interior profile deflects the incoming air upwards, causing an optimal spread of fresh air in the room.

- Insect mesh

- Burglar proof

The Invisivent® EVO range meets the requirements of burglary resistance class 2 according to standard prEN 1627 to 1630, and therefore suits to be used on a window class WK2.

 DucoPlus 60


Aluminium air inlet glazed-in windiows, thermally broken, for glass-units 20, 24 or 28mm thick. The air-inlet's style is plain, which ensures better water drainage. The intenral air deflector directs the cold air upwards. The perforated internal part of the casing acts as the anti-insect net. The air inlet may be handled manually, by a cord or a rod.

As inventor of humidity sensitive ventilation, Aereco develops innovative ventilation solutions for residential and commercial buildings. With a key concept – the modulation of airflow rates according to need – Aereco ventilation systems fully meet the actual demands of the building industry with regard to energy efficiency and indoor air quality.



Compatible with all profiles with resistance sealing.

Designed for direct assembly on the upper edge of the sash.

Colour: white or brown.

Type: pressurized and manual ventilation.

Automatic control. In the case of a strong wind, small valve closes the ventilation channel. When the wind stops blowing, the valve opens and activates internal and external air circulation.
