Variable Ventilation

The AH exhaust vent is a variable ventilation valve suitable for ventilating kitchens, bathrooms, and toilets.


Easy Cleaning

The AH variable exhaust valve is designed for minimum maintenance and easy cleaning without the risk of changing the air volume. 


The AH exhaust vent provides effective variable ventilation for a wide range of different contexts, including kitchens, bathrooms, and toilets. It can also be used in central ventilation systems in residential buildings. 

The AH exhaust vent is available in white and in a range of sizes. It is made of plastic and has high-quality construction. The aerodynamic shape ensures low sound levels. It is designed for direct wall mounting and includes a mounting ring. 

The AH vent has a humidity control which acts to increase the air volume when the air humidity rises and then switches back to the basic air volume when the air humidity decreases. This mechanical humidity control unit does not require a power supply. 

The central ventilation should be operated with constant pressure to ensure full functionality. The system does not have to be calibrated as in the case of systems with constant pressure. The overlapping and optimal height of the inflow ring avoids the build of dirt around the edges. This facilitates easy cleaning without the risk of changing the air volume.
