Abstract

A cover plate (30) with sound insulation (31) on the inside is secured on top of the mounting plate (20) for the fan wheel (19). The fan has a motor (18) housed inside a sheet metal casing (11) with an inlet (13) and an outlet (14).

Description

dysformig rund öppning 15 och husets översida 16 har en rund öppning 17 mitt för öppningen eller dysan 15. En elmotor 18 med fläkthjul 19 är fäst i en rund fästplåt 20 och denna fästplåt 20 är fäst med två gångjärn 21,22 i husets översida och kan fällas ner mot huset så att fläkthjulets centrala intagsöppning 23 kommer att ligga runt dysan 15 med tämligen liten spalt mot denna. Fästplåten 20 skruvas fast med fyra skruvar 24 i huset med en tätning däremellan. Den öppna gaveln 13 bildar ett inlopp från en sugledning och den öppna gaveln 14 bildar utlopp till en tryckledning. De öppna gavlarna är visade anpassade för ledningar med rektangulär tvärsektion, men man kan alternativt använda lösa gavlar med anslutningsstosar för anslutande ledningar som exempelvis kan vara plåtrör med rund tvärsektion. nozzle-shaped round opening 15 and the upper side 16 of the housing have a round opening 17 in the middle of the opening or nozzle 15. An electric motor 18 with k sprockets 19 is attached to a round mounting plate 20 and this mounting plate 20 is fixed with two hinges 21,22 in the upper side of the housing and can folds down towards the housing so that the central intake opening 23 of the fan wheel will lie around the nozzle 15 with a rather small gap towards it. The mounting plate 20 is screwed with four screws 24 in the housing with a seal in between. The open end 13 forms an inlet from a suction line and the open end 14 forms an outlet for a pressure line. The open ends are shown adapted for pipes with a rectangular cross-section, but you can alternatively use loose ends with connection sockets for connecting pipes which can, for example, be sheet metal pipes with a round cross-section.

När det inte är stora krav på ljudnivå används ventilationsfläkten så som den beskrivits ovan. När kraven är högre använder man en täckplåt 30 med invändig ljudisoleringsmatta 31 och fäster den så den täcker fästplåten 20 och lämpligen också hela eller åtminstone större delen av plåtsidan 16. Täckplàten 30 kan spännas fast eller skruvas fast. Det har visat dig att man med denna enkla och billiga ljudisoleringsmetod når en ljudreduktion av 3-5 dB på omgivningsljudet, vilket ofta är tillräckligt. Om man dessutom vill dämpa ljudet i insugningskanalen kan man komplettera med en enkel invändig isolering på insugningssidan utan att behöva isolera hela huset invändigt.When there are no great demands on the sound level, the ventilation fan is used as described above. When the requirements are higher, use a cover plate 30 with internal sound insulation mat 31 and fasten it so that it covers the mounting plate 20 and suitably also the whole or at least most of the plate side 16. The cover plate 30 can be clamped or screwed on. It has been shown to you that with this simple and inexpensive sound insulation method you achieve a sound reduction of 3-5 dB on the ambient sound, which is often enough. If you also want to attenuate the sound in the intake duct, you can supplement with a simple internal insulation on the intake side without having to insulate the entire house inside.
