Vent Axia Tempra Continuous Heat Recovery Unit
|
Please watch the video to the right in which we look at the Lo-Carbon Tempra Single Room Heat Recovery Extractor Fan from Vent Axia. Usually used as a continuous running fan with a trigger to boost, the Lo-Carbon Tempra will extract steam and moisture like a normal extractor fan, but it also draws fresh air back in via a specially constructed heat exchanger mounted though the wall. This fresh air, heated by the extracted air on its way out, replaces the extracted air and any heat lost at a 75% efficiency rate. The heat recovery function can be switched off for the summer months and the fan can also be run as a boost only fan without the trickle function engaged. |
- First in line is the Pullcord, a simple tug once for on or trigger to boost and tug again for off or return to trickle.
- The Lo-Carbon Tempra can also come fitted with a timer. Usually attached to the lighting circuit, the fan will be activated with the lights and then continue to run after the lights are switched off. This timer duration can then be adjusted from between 5 and 50 minutes.
- Finally, an internal humidistat senses the steam in the room and triggers the fan. This can then be adjusted to between 60% and 90% relative humidity to fine tune the sensitivity of the sensor.
- All models are also available in a 12v Low Voltage version for installation in Zone 1 of your bathroom and in two lengths for the heat exchanger, either a maximum wall depth of 321mm and a longer one with a max wall depth of 460mm. Make sure you are sure which wall depth you require before ordering.
