Features

The ELS NFC CO2 fan insert with designer inner facia and integrated CO2 sensor, available in either white or black and with an optical filter cleaning indicator as standard, is the convenient solution for ventilating sanitary rooms, interior bathrooms, toilets and other rooms in residential units, hotels and residential homes. It can also be used for exhaust air systems in accordance with DIN 1946-6. ELS NFC CO2 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. For each ventilation level, freely selectable time settings can be stored 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 CO2-dependent control enables fast and intensive ventilation. The fan switches on when the set CO2 threshold is reached and controls the volume flow depending on the CO2 measured value. The maximum CO2 value and CO2 threshold can be set between 400 and 3000 ppm. The maximum volume flow for CO2 operation can also be configured. Thanks to NFC technology, individual settings and customer-specific parameters can be configured either in the packaging when the power is off or after installation on site – quickly and easily using the Helios ELS app. The ELS NFC CO2 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.
