Acoustic expanded polyurethane is a material that allows for maximum sound absorption in silent extractors and extractors in general.\n\nThe soundproof units of the KSB series consist of a metal box and a centrifugal fan with a coupled electric motor. The motor is a two-pole asynchronous external rotor type with a centrifugal impeller and backward-curved blades. The Silent Extractor is built on anti-vibration mounts to absorb vibrations and therefore noise.\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\n \t\u003cli\u003eDiameter: 315 mm;\u003c\/li\u003e\n\n \t\u003cli\u003eCapacity: 2150 m³\/h;\u003c\/li\u003e\n\n \t\u003cli\u003ePower: 322W;\u003c\/li\u003e\n\n \t\u003cli\u003eCurrent: 1.4A;\u003c\/li\u003e\n\n \t\u003cli\u003eNoise level: 43dBA at 3m.\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"professional-growing","offers":[{"title":"Default Title","offer_id":55175068057942,"sku":"WC-22292","price":309.9,"currency_code":"EUR","in_stock":true}],"url":"https:\/\/professionalgrowing.com\/en\/products\/estrattore-silenziato-ksb-31-5cm-2150m3-h-vents","provider":"professional-growing","version":"1.0","type":"link"}
