The fan extracts 23 litres per second (83m³\/hr) at 28.5dBA measured at 3 metres, making it suitable for bathrooms, ensuites and small WCs where noise is a concern.\u003c\/p\u003e\n\u003cp\u003eDesigned for ceiling or wall mounting, the fan requires a 102mm diameter hole cut into plasterboard or masonry and recesses 78.4mm into the ceiling void, projecting 48.7mm below the ceiling line when installed. The IP45 rating allows installation in bathroom Zone 1 (the area directly above a bath or shower to 2.25m height). The motor is double-insulated Class II, so no earth connection is required during wiring.\u003c\/p\u003e\n\u003cp\u003eThe LED surround lights when the fan operates, providing a visual indicator that extraction is active. This LED effect is decorative only and does not replace standard bathroom lighting. The brushed steel finish on the faceplate is ABS plastic with a stainless steel-effect coating, pairing with chrome taps, towel rails and contemporary bathroom fittings. The fan complies with Part F (ventilation) and Part L (energy efficiency) of UK Building Regulations.\u003c\/p\u003e\n\u003cp\u003eThe overrun timer is preset to 2 minutes but adjustable up to 30 minutes via a dial accessed behind the faceplate, allowing the fan to continue extracting moisture after a shower finishes and the light switch is turned off. The 10.1W power draw and 0.438W\/(l\/s) SFP rating meet current energy efficiency standards for continuous and intermittent ventilation systems.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e157.6mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e157.6mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth\u003c\/td\u003e\n\u003ctd\u003e128.3mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e48.7mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecessed Depth\u003c\/td\u003e\n\u003ctd\u003e78.4mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCut-out Diameter\u003c\/td\u003e\n\u003ctd\u003e102mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003eABS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eStainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP Rating\u003c\/td\u003e\n\u003ctd\u003eIP45\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClass\u003c\/td\u003e\n\u003ctd\u003eII\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Voltage\u003c\/td\u003e\n\u003ctd\u003e230V 50Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEarth Terminal\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNoise Levels\u003c\/td\u003e\n\u003ctd\u003e28.5 - 30dB @ 3m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAirflow\u003c\/td\u003e\n\u003ctd\u003eAirflow: 23l\/s [82.8m3\/hr]\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSFP\u003c\/td\u003e\n\u003ctd\u003e0.438W \/ (l\/s)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOverrun Timer\u003c\/td\u003e\n\u003ctd\u003eOverrun timer settings: 2-30mins (Preset: 2mins)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\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-EX4TSS.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat bathroom zone can this fan be installed in?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe IP45 rating makes the EX4TSS suitable for Zone 1 installation, which is the area directly above a bath or shower up to 2.25m height.
