DVLI supply air valve

The DVLI is a diffuser with an aerodynamic design. Because of the materials used, the DVLI is very suitable for use in (very) wet areas like kitchens, bathrooms, etc. This diffuser has excellent properties with respect to noise level, pressure drop and airflow capacity. The design of this sound absorbing diffuser reduces the risk of crosstalk and noise. The diffuser is designed for both wall and ceiling mounting.

The design of the valve in combination with a foam ring prevents soiling of the ceiling and the walls.


  • quick and easy to install
  • very low noise level
  • good adjustment features
  • airflow is easy to measure


The air valve is made of white (RAL 9002) recyclable polypropylene, having a melting point between 150-180 °C. The diffuser is resistant to temperatures from 0 °C to 100 °C without deformation. The materials used are resistant to most chemicals in small concentrations.
