Features

The ELS NFC VOC fan insert with designer inner facia and integrated VOC sensor, available in either white or black and with an optical filter cleaning display as standard, is the convenient solution for ventilating sanitary rooms, bathrooms and toilets in residential units, hotels and residential homes. The ELS NFC VOC offers the options of up to 5 ventilation levels, including optional continuous ventilation and intermittent operation, with selectable volumetric flows of 7.5 to 100 m³/h. Freely selectable time settings can be stored for each ventilation level for a switch-on delay of up to 120 seconds, for a run-on of up to 90 minutes, and for the individually adjustable interval operation. The integrated stepless VOC-dependent control enables fast and intensive ventilation. The fan switches on when the set VOC threshold value is reached and controls the volume flow depending on the VOC measured value. You can choose between the VOC modes comfort (slow ventilation, acoustically comfortable) and intensive (ventilation with maximum volume flow). The maximum VOC value and the VOC threshold can be set between 100 and 450 voc. The maximum volume flow during VOC operation can also be configured. Thanks to NFC technology, individual settings and customer-specific parameters can be configured either in the packaging without the need for a power supply or after installation on site – quickly and easily using the Helios ELS app. The ELS NFC VOC is characterised by high pressure performance for a constant volume flow, combined with quiet ventilation operation thanks to proven ‘ultraSilence’ technology. The specially developed EC motor and the standard reusable permanent filter enable a very energy-saving and environmentally friendly use, with long-term low operating and service costs. The tool-free slide-in installation with simultaneous electrical contact closure also offers tradespeople a quick and easy installation.
