ACCESSORIES (are not included in the ATEX type examination certificate)

• S - gravity grilles, mounted outside. This prevents heat loss, wind, rain and birds. When the fan is running, the airflow opens the edges of the louvre and when the fan is switched off, the louvre closes by itself. The frame is made of steel sheets with an epoxy powder coating and the edges are made of technopolymer. The use of gravity grilles results in a slight reduction in performance

• D - adapter made of epoxy-painted steel sheet. It is required for the attachment of the fan when the width of the wall is less than dimension 'C' (the depth of the fan inlet). The frame shall be made of galvanised steel sheet (D63 and D71 epoxy powder-coated); the four corners shall be provided with 8 threaded inserts of galvanised steel sheet for the attachment of the fan on one side and of a gravity grille or protective mesh on the other

• R - impeller guard mesh, manufactured in accordance with UNI ISO 12499 and protected against atmospheric agents. This prevents accidental contact with the fan impeller. Frame and mesh made of epoxy-painted steel
