Featuring two installer-selectable motor speeds (2.7W or 4.8W), a built-in humidistat, and a 15-minute overrun timer, it automatically removes excess moisture from bathrooms, en-suites and shower rooms while consuming very little energy. Operating from just 12dB(A), it is one of the quietest domestic extractor fans available, making it ideal for modern homes where comfort is just as important as performance.The integrated humidistat continuously monitors humidity levels within the room. Whenever moisture rises above the selected threshold—typically after a bath or shower—the fan switches on automatically to extract warm, humid air before condensation can form. The fixed overrun timer ensures the fan continues operating after the light has been switched off, helping to eliminate residual moisture and reduce the risk of mould and damp.Designed with flexibility in mind, the 477436B can be installed on walls, ceilings, windows or panels and connects to standard 100mm ducting. Its stylish low-profile fascia, integrated backdraught shutter, energy-efficient motor and IPX5 rating make it an excellent choice for domestic bathrooms, cloakrooms and en-suite installations where reliable, near-silent ventilation is required.Features & BenefitsUltra-quiet operation from just 12dB(A)Ultra-low energy motor with 2.7W and 4.8W selectable power consumptionBuilt-in humidistat for fully automatic moisture controlFixed 15-minute overrun timerTwo installer-selectable airflow speedsSuitable for intermittent operationIntegral backdraught shutter prevents cold air entering the propertySuitable for wall, ceiling, window and panel mountingStandard 100mm (4") duct connectionIPX5 rated for bathroom installationsSuitable for Bathroom Zones 1 and 2 (subject to BS 7671)Helps prevent condensation, damp and mouldHigh-efficiency motor reduces running costsStylish low-profile white finishComplies with Building Regulations Approved Documents F and LTechnical SpecificationsManufacturer: Vent-AxiaProduct Code: 477436BModel: VASF100HTProduct Type: Silent Bathroom Extractor FanFan Type: AxialDuct Diameter: 100mm (4")Supply Voltage: 230V ACFrequency: 50/60HzPower Consumption: 2.7W (Low Speed) / 4.8W (High Speed)Operation: IntermittentHumidistat: Built-inTimer: Fixed 15-minute overrunSpeed Settings: Two (installer selectable)Maximum Extraction Rate: 15 litres/secondMaximum Airflow: 54m³/hourLow Speed Airflow: 21.6m³/hourNoise Level: From 12dB(A) at 3 metresMotor Type: High-efficiency motorBackdraught Shutter: IntegralMounting:WallCeilingWindowPanelIngress Protection: IPX5Bathroom Zones: Suitable for Zones 1 & 2 (subject to wiring regulations)Colour: WhiteDimensions:Height: 160mmWidth: 160mmDepth: 117mmCompliance:Building Regulations Approved Document FBuilding Regulations Approved Document LCertifications:UKCACEThree Reasons Customers Recommend This Product1.
