COMMITED WITH QUALITY, CHEAP OPTIONS CAN BE MORE EXPENSIVE IN THE LONG RUN Most important parts of the Wind Extractor or Spinning cowl Rivets vs Weld Points Advantage: The use of rivets for the union of each one of the pieces ensures the integrity of the whole indefinitely. Inconvenient: The welding points in systems in continuous movement are not safe and could be detached by the action of the wind ( see photos 1 and 4 ) Independent pieces vs One piece (premature cracking breakage) Advantage: The blades are assembled independently, ensuring the whole set by its rigidity Inconvenient: The...

COMMITED WITH QUALITY, CHEAP OPTIONS CAN BE MORE EXPENSIVE IN THE LONG RUN Possible failures in low quality Wind Ventilation Systems Photograph 1 Blade breakage due to wind action. Failure produced in the welding points of union between the blades and the moving neck, with the consequent entry of water The shaft has bent due to the action of the wind. The failure is due to the small diameter of the shaft, since this system does not have a stabilizing structure The design of this ventilation system can cause entry of water between the blades, because the blades start from the top without...
