Lo-Carbon Response 2016 by Vent-Axia

ci/sfb a new generation of lo-carbon continuous running fans 57.7 1st edition lo-carbon response/selv dmev

a new generation of lo-carbon continuous running fans looking towards the future vent-axia has been at the forefront of technical innovation in the ventilation industry for over 75 years manufactured in the uk the lo-carbon product range continues to develop and improve towards more energy efficient solutions things have moved on since the building regulations were first introduced over 20 years ago the lo-carbon response from vent-axia aims to satisfy and lead the ventilation market in overcoming the three key challenges which the government has centred their legislation around guaranteed installed performance part f of the building regulations state that once a ventilation product has been fitted the product must be commissioned and the installed performance of the unit measured and recorded this has previously been a time consuming task producing at times inaccurate results the integrated digital display showing the calibrated airflow and system pressure of the installed lo-carbon

dmev unit lo-carbon response costs under £1.50 per to year to run the specifiers choice the installers choice the home occupiers choice • the 100mm spigot is common with traditional intermittent extract fans simplifying the specification process • no need to test for airflow due to built in airflow display • • • the unique day-logger feature will enable landlords to monitor exactly how many days the fan has been running installation and commissioning time is significantly reduced with the innovative digital display showing the calibrated airflow l/s and system pressure pa of the installed product with discrete aesthetics and low noise levels due to an accurately balanced impeller the lo-carbon response is one of the most unobtrusive axial kitchen or bathroom fans available the high quality material means that there is no area for dirt to build up so the fan will look better for longer • safety first – the lo-carbon response has an ipx4

continuous decentralised ventilation providing comfort in our homes high pressure efficient airflow dynamic humidity sensor standard centrifugal fans which develop greater pressure are often not very efficient and can generate more noise axial fans are generally more energy efficient but usually run slowly and do not deliver a suitable pressure the lo-carbon response htp and selv htp models include a dynamic ambient response humidity sensor and work intelligently to ensure the correct level of ventilation is provided without wasting energy the lo-carbon response solves this problem the fan’s constant volume technology automatically adjusts the speed of the fan to ensure that the desired airflow is delivered using a silent high pressure axial fan the lo-carbon response can meet the ventilation requirements of most domestic installations without the need to use a centrifugal fan the fan senses the speed of the rise in humidity and controls the fan accordingly a slow rise in

dmev unit innovative digital display opportunity to prevent nuisance running at bath time following the introduction of the domestic ventilation compliance guide within part f 2010 and the requirement to test the installed airflow of extract fans the new lo-carbon response fan from vent-axia provides the easiest install available the intelligent lo-carbon response includes a silent running boost mode to ensure that even during periods of increased humidity for example when the occupier may be having a bath they will not be disturbed by the fan automatically switching to boost mode this feature delays the boost operation for a maximum of 20 minutes to reduce noise and cold drafts while bathing the fan then overruns the equivalent time after the light switch is switched off or 20 minutes whichever is shorter this mode is optional on installation be confident that the lo-carbon response is delivering the right performance with our unique digital display every 20 seconds the display will
