FAKRO roof windows are equipped with V40P semi-automatic air vents which create a healthier micro-climate and all year round savings. These vents are activated by changes in wind pressure to continually adjust levels of fresh air flow.
The V40P air vent is located in the upper part of the frame. The inlet itself contains an elastic, pneumatic flap which opens or closes to either deflect the inflow of air by reducing the duct area, or increases air flow in order to maintain a stable atmospheric level.
