    Thermostat Controlled

    The VTK air vent has a temperature-sensitive thermostat bulb which regulates the vent plate, adjusting the airflow depending on the temperature. 


    Easy to Install

    The VTK is easy to install into holes cut to size in the inner wall.


    The VTK air vent provides effective ventilation in a range of settings. The self-adjusting fresh air vent has a temperature-sensitive thermostat bulb which regulates the vent plate, adjusting the air gap and airflow according to the temperature outside. 

    When using the automatic setting, the valve disc will also reduce the air supply when the outside temperature falls and will increase the flow as the temperature rises. The setting can easily be adjusted. The VTK consists of an outer hood, a coarse dirt filter and a self-regulating valve. 

    The VTK is supplied complete with a thermostat bulb for temperatures between -5 and +10°C, plus an external grille and wall duct. Spacers for maintaining minimum airflow are available as an accessory.
