Installed on an external wall, the unit continuously introduces filtered fresh air into the property to help reduce \u003cstrong\u003econdensation, mould, excess humidity and stale indoor air\u003c\/strong\u003e.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    Fresh air is drawn from outside, passed through the integral filter and gently supplied into the dwelling. This creates positive air pressure that encourages moisture-laden and stale air to leave through natural leakage paths and existing extract points. The result is improved indoor air quality and an effective solution for properties affected by streaming windows, musty odours and surface condensation.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eIntegral Comfort Heater\u003c\/h3\u003e\n\n  \u003cp\u003e\n    The EVF-H incorporates an \u003cstrong\u003eintelligent comfort heater\u003c\/strong\u003e to temper incoming fresh air during colder weather. A temperature sensor monitors the incoming air and controls the tubular heater to help maintain a comfortable supply air temperature of approximately \u003cstrong\u003e10°C\u003c\/strong\u003e. Two independent safety cut-outs provide additional protection by shutting down the heater in the event of fan failure.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    A separate heater enable and disable switch allows the heating function to be switched off when it is not required, helping minimise energy consumption during warmer periods.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eLow Energy \u0026amp; Quiet Operation\u003c\/h3\u003e\n\n  \u003cp\u003e\n    Powered by an \u003cstrong\u003eultra-low watt brushless DC motor\u003c\/strong\u003e with sealed-for-life ball bearings, the EVF-H is designed for continuous, energy-efficient operation. Its forward-curved centrifugal fan provides multiple airflow settings, with approximately \u003cstrong\u003e9–23 litres per second\u003c\/strong\u003e available depending on the selected operating rate.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    Quiet performance makes the unit particularly suitable for occupied residential properties, with outlet sound levels of less than \u003cstrong\u003e15dB(A) at 3 metres\u003c\/strong\u003e on the trickle setting and approximately \u003cstrong\u003e20.3dB(A)\u003c\/strong\u003e on boost.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eKey Features\u003c\/h3\u003e\n\n  \u003cul\u003e\n    \u003cli\u003eWall mounted Positive Input Ventilation (PIV) system\u003c\/li\u003e\n    \u003cli\u003eDesigned for flats and apartments without suitable loft space\u003c\/li\u003e\n    \u003cli\u003eProvides continuous filtered fresh air throughout the dwelling\u003c\/li\u003e\n    \u003cli\u003eHelps reduce condensation, black mould and excess humidity\u003c\/li\u003e\n    \u003cli\u003eHelps minimise streaming windows and musty odours\u003c\/li\u003e\n    \u003cli\u003eIntegral intelligent comfort heater for tempering incoming air\u003c\/li\u003e\n    \u003cli\u003eHelps maintain incoming supply air at approximately 10°C during cold conditions\u003c\/li\u003e\n    \u003cli\u003eTwo independent heater safety cut-outs\u003c\/li\u003e\n    \u003cli\u003eSeparate heater enable and disable control\u003c\/li\u003e\n    \u003cli\u003eUltra-low watt brushless DC motor\u003c\/li\u003e\n    \u003cli\u003eSealed-for-life ball bearings for reliable continuous operation\u003c\/li\u003e\n    \u003cli\u003eForward-curved centrifugal fan\u003c\/li\u003e\n    \u003cli\u003eMultiple airflow settings including trickle and boost\u003c\/li\u003e\n    \u003cli\u003eAirflow performance of approximately 9–23 l\/s\u003c\/li\u003e\n    \u003cli\u003eSpecific fan power of approximately 0.29–0.39 W\/l\/s depending on setting\u003c\/li\u003e\n    \u003cli\u003eVery quiet operation with sound levels below 15dB(A) at trickle\u003c\/li\u003e\n    \u003cli\u003eIntegral hours-run meter for operation and maintenance monitoring\u003c\/li\u003e\n    \u003cli\u003eLong-life integral air quality and insect filter\u003c\/li\u003e\n    \u003cli\u003eRecommended filter cleaning or replacement approximately every 24–36 months, depending on conditions\u003c\/li\u003e\n    \u003cli\u003eSupplied with external louvre grille\u003c\/li\u003e\n    \u003cli\u003e100mm spigot for connection to circular ducting\u003c\/li\u003e\n    \u003cli\u003eCompact wall-mounted design\u003c\/li\u003e\n    \u003cli\u003eSuitable for retrofit and new-build applications\u003c\/li\u003e\n    \u003cli\u003e230V AC electrical supply\u003c\/li\u003e\n    \u003cli\u003eBBA approved\u003c\/li\u003e\n    \u003cli\u003e5-year warranty\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003ePerformance\u003c\/h3\u003e\n\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTrickle airflow:\u003c\/strong\u003e Approximately 9–10 l\/s\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTrickle power consumption:\u003c\/strong\u003e Approximately 3.4–3.6W\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTrickle sound level:\u003c\/strong\u003e Less than 15dB(A) at 3m\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBoost airflow:\u003c\/strong\u003e Approximately 20–23 l\/s\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBoost power consumption:\u003c\/strong\u003e Approximately 6.1–7.4W\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBoost sound level:\u003c\/strong\u003e Approximately 20.3dB(A) at 3m\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eDimensions \u0026amp; Specification\u003c\/h3\u003e\n\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e Approximately 505mm\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e Approximately 380mm\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDepth:\u003c\/strong\u003e Approximately 185mm\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDuct connection:\u003c\/strong\u003e 100mm\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSupply:\u003c\/strong\u003e 230V AC\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e External wall mounted\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Whole-house ventilation and condensation control\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\n  \u003cp\u003e\n    The EnviroVent EVF-H is particularly suitable for \u003cstrong\u003eflats, apartments, social housing and private rented properties\u003c\/strong\u003e experiencing persistent condensation, mould, high humidity or poor indoor air quality.
