This ventilator integrates an extremely sturdy cast aluminium hood.
His ABS closing valve, safe and easy to use, is equipped with a spring pop-out knob ON / OFF device. Integrated blades inside the body improve watertightness by splitting the water intrusion. Watertightness is provided using rubber seal systems which avoid applying sealant, for a faster and cleaner fitting.
Thanks to the fixing from the inside, the cover is smooth and without drilling. The cut-out diameter is identical to that of other Goiot ventilators, for an easy adaptation.
Optionally, Goiot offers its hatches with an integrated ventilator.
