The aluminium construction allows the duct to expand and compress along its length, making it easier to route through tight spaces or around obstacles during installation.\u003c\/p\u003e\n\u003cp\u003eDesigned for residential and light commercial ventilation applications, the kit suits extractor fans in kitchens, bathrooms and utility rooms, inline fans for loft ventilation, and portable air conditioning units that require an exhaust run to a window or external vent. The 100mm internal diameter matches common UK extractor fan outlet sizes, and the supplied jubilee clips fit securely over the corrugated exterior to create an airtight seal at each connection point.\u003c\/p\u003e\n\u003cp\u003eThe aluminium foil and wire construction is lightweight enough to be supported by standard duct brackets or cable ties without sagging, while remaining puncture-resistant during installation through wall cavities or ceiling voids. The duct can be compressed to approximately 600mm for transport and storage, then extended to the full 3.3m length on site. The 110mm cut-out diameter specification refers to the outer diameter of the corrugated profile, allowing clearance when passing the duct through wall apertures or ceiling grilles.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e108 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e3300 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecessed Depth\u003c\/td\u003e\n\u003ctd\u003e3300 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCut-out Diameter\u003c\/td\u003e\n\u003ctd\u003e110 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003eAluminium\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\/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_1503992_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 are the jubilee clips for?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe two stainless steel jubilee clips secure each end of the duct to the extractor fan outlet and the external vent or grille.

The aluminium foil and wire construction can be cut with heavy-duty scissors or tin snips if you need a shorter run than 3.3m. Cut cleanly across the corrugations to avoid fraying the edges.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the duct suitable for high-temperature applications?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eStandard aluminium ducting handles air temperatures up to approximately 120°C, which covers typical kitchen extractor and bathroom fan applications.
