Lo-Carbon Solo Plus



The Lo-Carbon Solo Plus range from Vent-Axia has been specially designed for through the wall and ducted applications, suitable for internal bathrooms, WC’s and other small rooms. Finished in white, the Lo-Carbon Solo Plus can be flush or surface mounted, with a 2-position 100mm circular spigot for rear entry or connecting to a vertical ducting system. The new Lo-Carbon Solo Plus has an adjustable boost speed which is set at installation variable between 57-105m3/h for boost/override operation to meet Building Regulations thus ensuring minimum energy usage and low sound levels. All models have an optional speed for constant trickle ventilation (25m3/h), selectable at installation. Depending on the model, the fan will switch from trickle (if selected) to boost via the pullcord/light switch/humidity sensor/PIR. Four models are available offering features such as, Pullcord, Timer, Humidistat/Timer or PIR versions. All models can be wall; panel or ceiling mounted and can be connected to either circular, rectangular or Vent-Axia’s System 25 flat ducting, which has been specially designed for concealed applications that can benefit from its ultra slim 25mm depth. Cable entry is achieved through a rear entry grommet on the top right hand side of the unit. Enclosure of the electrical components is manufactured from flame retardant grade material. Supply voltage 220-240V/1/50Hz. Motor Incorporated into the Lo-Carbon Solo Plus is a highly efficient DC long life ball bearing motor. DC motors offer the benefit of over 80% efficiency over conventional shaded pole motors within their class. The fully enclosed motor is fixed onto a 3 position anti-vibration mount which offers higher reliability and lower noise.
