In a room equipped with modern windows, to ensure the proper amount of air ventilation, it is required to frequently reverse or open the window casements, or to install air diffusers.

Diffusers are devices introducing air into the living areas, office or kitchen, located in the upper part of a window – according to the Polish Norm of Ventilation (PN-83 / B-03430). According to the principles of ventilation, air is supplied through air vents into the rooms such as: living rooms, bedrooms, kitchens, and is derived in bathrooms and kitchens through the vents.

Direct benefits from the use of diffusers are:


  • Eliminating the occurrence of condensation of water vapor on windows and lintels (no mold and mildew)

  • Less heat loss compared to the frequent evasion and opening windows, or even the use of the function micro-unsealing

  • Thermal comfort in rooms (no drafts)

  • Increased acoustic performance compared with unsealed or tilted window

  • In the case of controlled air inlets, automatic operation of the entire ventilation system

We offer three basic types of diffusers:

  • Diffusers controlled manually (User adjusts the diffuser, deciding on the amount of air supplied by manually changing the position of the throttle of the diffuser)

  • Pressure Diffusers (the amount of supplied air depends on the pressure difference inside and outside the room. This is to the level differential pressure at which the diffuser air flow reaches maximum. On further growth the wings deflect reducing the amount of air. This may be due to, e.g.  gust of wind. User has the possibility of closing the aperture limiting the airflow to a minimum)

  • Automatic humidity-controlled diffusers – (the volume of airflow rate is dependent on the amount of water vapor in the room – with increasing humidity insie, the ventilator opens automatically)
