This static ventilator is made with three parts: 1) a hollow housing, triangular shaped with circumferential sidewalls and louvers attached to the outside walls, 2) a triangular shaped base fixed to the roof and 3) a cap at the top. The hollow housing is the part that actually does the ventilation. Each of its louvers is inclined downwards and out and comes with a piece of filter material preventing anything from entering the vent openings and allowing the air to circulate. The triangular shape of the hollow housing allows the wind to slide laterally along each side of the ventilator and prevents any snow or debris accumulation at the base and on the louvers of the ventilator. In order to secure the hollow housing to the roof surface, a triangular shaped piece serves as a base where the hollow housing is inserted. This base also lets the condensed water flow out of the hollow housing. The cap seals the hollow housing and prevents anything from falling straight into the ventilator.
