Available in a variety of diameters and lengths to suit any fan\/ducting size.

Older fans also regularly suffer from misaligned blades and worn out ball-bearings from wear and tear of extended usage. This will slowly inrease the noise generated by the fan as it ages.\u003c\/p\u003e\n\u003cp\u003eSecond (and often the most overlooked) is the sound of the air turbulence, generated by the air moving and crashing through the ducting.\u003c\/p\u003e\n\u003ch3\u003eHow do I Solve it?\u003c\/h3\u003e\n\u003cp\u003eNoise generated by the fan itself can be solved by upgrading to a \u003ca href=\"https:\/\/hytachydroponics.com\/collections\/ec-extraction-fans\"\u003e\u003cstrong\u003enew EC fan\u003c\/strong\u003e\u003c\/a\u003e, with the Silent versions being the best choice for growers wanting minimal noise. \u003ca href=\"https:\/\/hytachydroponics.com\/collections\/ec-extraction-fans\/products\/phresh-hyperfan-stealth-v2\"\u003e\u003cstrong\u003ePhresh Hyperfan Stealth\u003c\/strong\u003e\u003c\/a\u003e, \u003ca href=\"https:\/\/hytachydroponics.com\/collections\/ec-extraction-fans\/products\/rhino-ultra-silent\"\u003e\u003cstrong\u003eRhino EC Ultra Silent\u003c\/strong\u003e\u003c\/a\u003e and \u003ca href=\"https:\/\/hytachydroponics.com\/collections\/ec-extraction-fans\/products\/u-go-silent-ec-fans-with-controller\"\u003e\u003cstrong\u003eUGO Silent EC\u003c\/strong\u003e\u003c\/a\u003e are the most popular choices out there. EC fans also don't come with the annoying buzzing\/humming noise when running at lower speeds (unlike AC Fans), and come with a linear speed controller as standard. This gives growers the power to precisely select their fan speed, avoiding unecessary noise, saving electricity and increasing product lifespan.\u003c\/p\u003e\n\u003cp\u003eWhen it comes to dealing with the noise generated from turbulence within the ducting, there are two ways to tackle this. Firstly, upgrading ducting to a \u003ca href=\"https:\/\/hytachydroponics.com\/collections\/ducting-metalwork-clamps\/products\/ultra-silent-ducting\"\u003e\u003cstrong\u003eUltra Silent\u003c\/strong\u003e\u003c\/a\u003e version will dampen the noise as it passes through, however some noise will still be present as the air exits the duct system. This is where the silencer shines, acting as a large muffler to deal with the excess noise before it leaves.\u003c\/p\u003e\n\u003ch3\u003eSilencedAir Fan Silencers\u003c\/h3\u003e\n\u003cp\u003eUse a SilencedAir Fan Silencer to absorb this unwanted noise. Even two silencers can be used in series where unwanted noise is a particular problem.\u003c\/p\u003e\n\u003cp\u003eSilencedAirs are most effective if positioned directly after a fan, after a tight bend in duct work, or at the very end of your ducting line. These high quality silencers are airtight and can be used in sealed ventilation and closed-looop systems.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEffectively reduces noise in ventilation systems\u003c\/li\u003e\n\u003cli\u003eHigh quality galvanised steel, built to last\u003c\/li\u003e\n\u003cli\u003eFast and easy to install\u003c\/li\u003e\n\u003cli\u003eTwo can be used in series for maximum noise reduction\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"G.A.S","offers":[{"title":"150 x 600","offer_id":51811184214348,"sku":"","price":79.95,"currency_code":"GBP","in_stock":true},{"title":"200 x 600","offer_id":51811184247116,"sku":"","price":94.95,"currency_code":"GBP","in_stock":true},{"title":"250 x 600","offer_id":51811184279884,"sku":"","price":109.95,"currency_code":"GBP","in_stock":true},{"title":"315 x 600","offer_id":51811184312652,"sku":"","price":134.95,"currency_code":"GBP","in_stock":true},{"title":"355 x 600","offer_id":51811184345420,"sku":"","price":149.95,"currency_code":"GBP","in_stock":true},{"title":"250 x 900","offer_id":51811184378188,"sku":"","price":139.95,"currency_code":"GBP","in_stock":true},{"title":"315 x 900","offer_id":51811184410956,"sku":"","price":174.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0789\/3044\/4620\/files\/SilencedAir-Fan-Silencer-group.jpg?v=1737379489","url":"https:\/\/hytachydroponics.com\/products\/silencedair-fan-silencers","provider":"Hytec Horticulture","version":"1.0","type":"link"}
