Wall vents are an alternative to window vents. They can be installed in both wall conduit and the cassette of roller blinds. Along with additional accessories they ensure high acoustic insulation among all the humidity controlled vents. Wall vents are ideal for new buildings as well as buildings undergoing modernization.

We offer automatically controlled wall vents. Air flow is dependent on the water vapor content (relative humidity) inside the room, i.e. air impurities resulting from activities such as washing, cooking, drying, etc. The control sensor is a polyamide strip, which influenced by changes in the relative humidity of air changes its length, causing a greater or smaller opening of the damper, and thus allowing a greater or lesser air flow into the room.


The operation principle of wall vents

  • Wall vents operate in the range of 35 to 70% relative humidity. If the humidity is less than or equal to 35%, the vent is sealed off, and minimal airflow is directed into the room. With the increase in moisture content the vent opens and when at a value of 70% or more the maximum capacity is achieved
  • Window vents are designed so that outside air does not come into direct contact with the sensor. Thanks to this, the conditions inside are analyzed, instead of the outside
  • Can be locked in position, at which a minimum, steady flow of air is obtained
  • Depending on the type of installation, the airflow direction changes (up vertically or diagonally)
  • The vent operates without human intervention and does not require a power supply.
