The timer comes preset to 2 minutes and can be adjusted via a dial on the fan body before installation. Running at 9.7W on 230V mains, the fan extracts 24 litres per second (87m³\/hr) while generating 28.5-30dBA of noise at 3 metres.\u003c\/p\u003e\n\u003cp\u003eDesigned for domestic bathrooms, en-suites and small utility rooms, the fan carries an IP45 rating making it suitable for Zone 1 bathroom installation (the area directly above a bath or shower up to 2.25m height). The fan can be mounted on a wall or ceiling and requires a 102mm diameter cut-out in plasterboard, timber or masonry. A back draught shutter is built into the unit to prevent cold air flowing back through the ductwork when the fan is off.\u003c\/p\u003e\n\u003cp\u003eThe white ABS plastic grille sits almost flush with the wall or ceiling, projecting just 49.9mm from the surface once installed. The fan housing recesses 78.5mm into the wall cavity or ceiling void, so check void depth before ordering. Double-insulated Class II construction means no earth wire is required during installation. The fan complies with Building Regulations Part F (ventilation) and Part L (energy efficiency) with a specific fan power (SFP) of 0.401W per litre per second.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\" style=\"width: 100.036%; height: 333.2px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 26.1676%; height: 19.6px;\"\u003eHeight\u003c\/td\u003e\n\u003ctd style=\"width: 71.3725%; height: 19.6px;\"\u003e157.6mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 26.1676%; height: 19.6px;\"\u003eWidth\u003c\/td\u003e\n\u003ctd style=\"width: 71.3725%; height: 19.6px;\"\u003e157.6mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 26.1676%; height: 19.6px;\"\u003eDepth\u003c\/td\u003e\n\u003ctd style=\"width: 71.3725%; height: 19.6px;\"\u003e127.2mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 26.1676%; height: 19.6px;\"\u003eProjection\u003c\/td\u003e\n\u003ctd style=\"width: 71.3725%; height: 19.6px;\"\u003e49.9mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 26.1676%; height: 19.6px;\"\u003eRecessed Depth\u003c\/td\u003e\n\u003ctd style=\"width: 71.3725%; height: 19.6px;\"\u003e78.5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 26.1676%; height: 19.6px;\"\u003eCut-out Diameter\u003c\/td\u003e\n\u003ctd style=\"width: 71.3725%; height: 19.6px;\"\u003e102mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 26.1676%; height: 19.6px;\"\u003eConstruction\u003c\/td\u003e\n\u003ctd style=\"width: 71.3725%; height: 19.6px;\"\u003eABS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 26.1676%; height: 19.6px;\"\u003eFinish\u003c\/td\u003e\n\u003ctd style=\"width: 71.3725%; height: 19.6px;\"\u003eWhite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 26.1676%; height: 19.6px;\"\u003eIP Rating\u003c\/td\u003e\n\u003ctd style=\"width: 71.3725%; height: 19.6px;\"\u003eIP45\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 26.1676%; height: 19.6px;\"\u003eClass\u003c\/td\u003e\n\u003ctd style=\"width: 71.3725%; height: 19.6px;\"\u003eII\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 26.1676%; height: 19.6px;\"\u003ePrimary Voltage\u003c\/td\u003e\n\u003ctd style=\"width: 71.3725%; height: 19.6px;\"\u003e230V 50Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 26.1676%; height: 19.6px;\"\u003eEarth Terminal\u003c\/td\u003e\n\u003ctd style=\"width: 71.3725%; height: 19.6px;\"\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 26.1676%; height: 19.6px;\"\u003eNoise Levels\u003c\/td\u003e\n\u003ctd style=\"width: 71.3725%; height: 19.6px;\"\u003e28.5 - 30dB @ 3m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 26.1676%; height: 19.6px;\"\u003eAirflow\u003c\/td\u003e\n\u003ctd style=\"width: 71.3725%; height: 19.6px;\"\u003eAirflow: 24l\/s [86.93m3\/hr]\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 26.1676%; height: 19.6px;\"\u003eSFP\u003c\/td\u003e\n\u003ctd style=\"width: 71.3725%; height: 19.6px;\"\u003e0.401W \/ (l\/s)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 26.1676%; height: 19.6px;\"\u003eOverrun Timer\u003c\/td\u003e\n\u003ctd style=\"width: 71.3725%; height: 19.6px;\"\u003eOverrun timer settings: 2-30mins (Preset: 2mins)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 26.1676%; height: 19.6px;\"\u003eWarranty\u003c\/td\u003e\n\u003ctd style=\"width: 71.3725%; height: 19.6px;\"\u003e3 Year Guarantee\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/datasheet-EX1TWH.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat ceiling or wall void depth is needed?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe fan housing recesses 78.5mm into the wall cavity or ceiling void.
