A silencer takes noise out of that decision, so the fan can run at the speed the space actually needs.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall inline\u003c\/strong\u003e with an existing fan and ducting run, on the intake or exhaust side\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit downstream of the fan or air handling unit\u003c\/strong\u003e for the best noise reduction, and add a second silencer upstream for maximum effect\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecure with ducting clamps\u003c\/strong\u003e at both spigots and connect ducting to each end\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupport the weight\u003c\/strong\u003e of the silencer independently rather than leaving it hanging on the ducting alone\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv class=\"hcs-specs\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Blauberg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Galvanised steel, 50mm high-density mineral wool acoustic lining\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 600mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSizes:\u003c\/strong\u003e 250mm (10\") and 315mm (12\") duct connections\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNoise reduction:\u003c\/strong\u003e Up to 22dB at 1000Hz (250mm) \/ up to 17dB at 1000Hz (315mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnections:\u003c\/strong\u003e Rubber-sealed spigots\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting:\u003c\/strong\u003e Inline with round ducting, either direction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Blauberg","offers":[{"title":"250mm 10\" - 600mm","offer_id":53798859997450,"sku":"ENV-BLAU-002-01","price":90.45,"currency_code":"GBP","in_stock":true},{"title":"315mm 12\" - 600mm","offer_id":53798860030218,"sku":"ENV-SILE-003-01","price":119.25,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/blauberg-solid-silencer-1.png?v=1790169253","url":"https:\/\/hydrocropshop.co.uk\/products\/blauberg-solid-silencer","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
