A short run of acoustic ducting on the extraction side takes real edge off the hum without killing airflow. We've used it enough times to know it works — noticeable difference, simple install, proper value for money.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cp\u003eVortex Acoustic Ducting is a \u003cstrong\u003esound-insulated ventilation duct\u003c\/strong\u003e that reduces the noise generated by extraction fans and moving air in grow rooms and tents. Built with a perforated inner core, a layer of acoustic fibreglass insulation, and a durable outer flexi-layer, it lets air move freely while stopping vibration from travelling down the ducting. Think of it as a silencer for your ventilation system — not magic, but genuinely effective.\u003c\/p\u003e\n\n\u003ch3\u003eHow it compares\u003c\/h3\u003e\n\u003cp\u003eVortex Acoustic sits in the \u003cstrong\u003emid-range noise-control segment\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eStandard aluminium or combi ducting: cheapest, zero sound dampening\u003c\/li\u003e\n\u003cli\u003eVortex Acoustic Ducting: proven fibreglass insulation, widely stocked, entry-level acoustic pricing\u003c\/li\u003e\n\u003cli\u003ePremium alternatives (Phonic Trap, Ultra Silent): higher price point, marginal gains for most setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIn plain terms — you get proper noise reduction at a price that doesn't require a second mortgage.

Even a 1–2 metre run makes a real difference. Many growers use acoustic on the noisy bit and standard ducting elsewhere to manage cost.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eInstallation\u003c\/strong\u003e\u003cbr\u003e\nFits directly over the flange of your extractor fan or filter — no specialist tools needed. Secure with a duct clip to hold it tight. The ducting is flexible enough to run around corners; just try to avoid sharp right angles where possible, as gentle bends reduce turbulence and noise further.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eOptimization\u003c\/strong\u003e\u003cbr\u003e\nAcoustic ducting works best when combined with other noise-reduction measures. Pair it with a silencer on the exit, or hang your fan from bungee cords to isolate vibration. Together, these three things (acoustic ducting, silencer, fan isolation) can make your ventilation genuinely discreet.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat it won't do\u003c\/strong\u003e\u003cbr\u003e\nIt won't silence the fan itself — just the noise from air rushing through the duct. If the fan motor is loud, that's a separate problem (bungee isolation or a quieter fan helps there).\u003c\/p\u003e\n\n\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLength: \u003cstrong\u003e5 metres\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eAvailable diameters: \u003cstrong\u003e100mm (4″), 125mm (5″), 150mm (6″), 200mm (8″), 250mm (10″), 315mm (12″)\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eConstruction: \u003cstrong\u003eInner perforated flexi-ducting + fibreglass insulation layer + outer polyester laminated flexi-ducting\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eHelix: \u003cstrong\u003eHigh tensile steel wire spiral\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eCoating: \u003cstrong\u003ePolyester laminated\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eFire resistance: \u003cstrong\u003eTested and certified\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eFlexibility: \u003cstrong\u003eFlexible and hard-wearing; can bend without creasing\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eHeat emission: \u003cstrong\u003eLower than standard ducting due to fibreglass insulation\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWho this is for\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eGrowers in noise-sensitive environments (bedrooms, lofts, shared housing)\u003c\/li\u003e\n\u003cli\u003eAnyone running extraction fans where noise carries to neighbours or family\u003c\/li\u003e\n\u003cli\u003eSetups where everything else is dialled in but the ventilation hum is still a problem\u003c\/li\u003e\n\u003cli\u003eBudget-conscious growers who want acoustic benefits without premium pricing\u003c\/li\u003e\n\u003cli\u003eFirst-time upgrade buyers wanting noticeable results without system overhaul\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eParticularly suited to growers who need \u003cstrong\u003estealth ventilation\u003c\/strong\u003e without rebuilding their entire setup.\u003c\/p\u003e\n\n\u003ch3\u003eOur take\u003c\/h3\u003e\n\u003cp\u003eThis is proper ducting that does exactly what it claims — cuts noise without strangling airflow.
