Description

Invisivent® EVO AK is an acoustic version of the well-known Invisivent® EVO, a discrete, self-regulating overframe ventilator. Invisivent® EVO AK is nearly invisible from the outside due to it's installation on top of the window frame. This almost invisible installation guarantees maximum light penetration since the glass size is not reduced. Invisivent®EVO AK always lines up perfectly with the window frame thanks to the easy click and slide assembly system.

Three different types of the Invisivent® EVO AK are available: Invisivent® EVO AK basic, Invisivent® EVO AK high and Invisivent® EVO AK extreme; each with a different airflow and different level of sound reduction. The need for an external sound reducing module is rendered unnecessary by the integration of the sound reducing material inside the middle PVC profile. This allows for an impeccable finish.

In closed position there is no visual difference between the Invisivent® EVO AK and Invisivent® EVO, so both models can be used in the same building.

Features:

  • Self-regulating class P3 (except Extreme version).
  • Integrated sound reducing material: no need for an external acoustic module.
  • Hidden installation with maximum respect for the architecture.
  • Natural, energy-efficient comfort solution.
  • Easy maintenance, thanks to the removable internal flap.
  • Burglar-proof, ventilation with windows closed (burglar resistance class WK2).
  • Rain and insect-proof.
