The vent accepts both rigid and flexible duct connections and sits flush against brickwork, blockwork or cavity walls once the 100mm circular aperture is cut.\u003c\/p\u003e\n\u003cp\u003eDesigned for kitchens, bathrooms, utility rooms and other spaces requiring mechanical ventilation to the outside, the vent pairs with standard 100mm axial extractor fans and inline duct fans. The louvered design allows air to exit while the mesh screen behind the louvers prevents insects, debris and larger airborne particles from entering the duct when the fan is not running. The front grille is removable, allowing access to clean the flyscreen without disconnecting the duct.\u003c\/p\u003e\n\u003cp\u003eThe 152mm square faceplate projects 16mm from the wall surface once installed, with a recessed depth of 48mm behind the wall to accommodate the duct connection spigot. The white polycarbonate construction resists UV degradation and moisture, making it suitable for both sheltered external walls and high-humidity internal installations. The material is lighter and more impact-resistant than metal grilles of equivalent size.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e152 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e152 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e16 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecessed Depth\u003c\/td\u003e\n\u003ctd\u003e48 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCut-out Diameter\u003c\/td\u003e\n\u003ctd\u003e100 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003ePolycarbonate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eWhite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_1503973_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat size hole is needed in the wall?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA 100mm (4-inch) circular aperture is required.
