Perfect facade ventilation: flexibly combinable ventilator types, with a uniform appearance. Easy to plan and easy to install.

Si-web Aeromat-vt Head

State-of-the-art facade ventilation.

Technically demanding projects require an efficient ventilation system that can be harmoniously and flexibly integrated into any building. The AEROMAT VT facade ventilator combines decentralised room ventilation with high additional benefits. It adapts perfectly to the particular requirements due to the freely selectable combination of the individual device types. On a uniform platform of covers with a unit height of only 100 mm, it can be individually configured with five device variants and extensive installation and equipment options. The fabrication, assembly and installation is also quick and easy. The new EPP duct flexibly adapts to the structural conditions and the fabrication is easy and time-saving thanks to its flexible material.

Compact facade ventilator with heat recovery, optimal air throughput and effective sound absorption.

The AEROMAT VT WRG and AEROMAT VT WRG plus facade ventilators do not only stand for high air throughput and low inherent noise, they also generally stand for a wide range of comfort and solution options. The efficient heat recovery, the intelligent filter technology and the integrated, automatic air quality and humidity control make it a valuable building block towards a healthy indoor environment. The "smart" variant of the ventilator can also be controlled via the SIEGENIA Comfort app for even more room comfort.

Motor-operated active vent for supply air or exhaust air operation.

The air supply units and exhaust air units of the AEROMAT VT system are essential for implementing the widest range of ventilation scenarios. Equipped with an especially quiet radial fan, the AEROMAT VT A and AEROMAT VT Z offer a high air throughput and effective sound absorption. In this way, in combination with sound absorbent windows, calmness is restored along with the healthy fresh air even in times of high noise pollution.

Passive pressure differential ventilator with optimum ratio of air throughput and sound absorption.

The air exchange is accomplished via the natural pressure differential between cool outside air and heated, used indoor air. This provides a comfortable and healthy indoor environment without power consumption and without noise pollution and also predestines the ventilator for use in bedrooms and living rooms. Its optimum ratio of air throughput and sound absorption makes the AEROMAT VT D ideal as a passive air ventilator.


  • Dimensions, H x L x D: 100 mm x 500 – 6000 mm x 200 – 500 mm
  • Air throughput: up to 58 m³/h at 8 Pa
  • Sound absorption Dn,e,w: up to 64 dB

CO₂ regulation

Air quality sensors for the best indoor air.

All variants of the AEROMAT VT can be equipped optionally with CO₂-regulation. This means that spent air is easily detected and the air exchange is adapted according to demand via the automatic mode. The quality of the indoor air is made visible at a glance via the traffic light display in the SIEGENIA Comfort app. Hence, a high quality of air is guaranteed at all times and the risk of viruses in the indoor air is significantly reduced.

EPP ducts

Clean appearance, clear benefits: installation with EPP ducts.

The AEROMAT VT system has been developed to adapt optimally to the architecture. The wide range of installation locations around the window is not the only convincing feature. Matching EPP ducts also ensure flexible adaptation to the structural conditions and an unobstructed exterior view. Moreover, this enables the further optimisation of the sound absorption.

Innovative NOx filter

The best filter solution against nitrogen oxides, fine dust and pollen.

With the new NOx filter, you are not only offering a solution against pollen and fine dust, but also against nitrogen oxides. Thus you can achieve a considerably better quality of fresh air even in large cities. The NOx filter extracts even the finest harmful or irritating substances from the air and has been specially developed for nitrogen oxides arising from combustion engines and combustion plants, in particular. In particular, nitrogen dioxide (NO2) is contained to a high degree in car exhaust fumes and can become a serious problem, especially for asthmatics.

  • Protection against nitrogen oxides, especially NO2 due to car exhaust fumes
  • Protection against pollen, valuable for allergy sufferers
  • Protection against fine dust (filter grade ISO ePM10 50%)
  • Can also be retrofitted and replaced without problems
  • Maintenance reminder via a filter replacement indicator

Versatile operating options.

The AEROMAT VT offers maximum flexibility when it comes to operation and control: on the unit itself via Touch Control, via the ventilation control unit that is mounted on the wall as an external control unit, using smart technology via the SIEGENIA Comfort app or externally through the building management system.
