The Vent-Axia Lo-Carbon Tempra through the wall heat recovery units are suitable for fitting through a 102mm (4”) circular hole and are designed for use in bathrooms, toilets and utility areas. Under the new Building Regulations Document F continuous running products, such as the Lo-Carbon Tempra only need to move the amount of air as laid down in table 5.1a of Document F. The Vent-Axia Lo-Carbon Tempra is available with pullcord control, timer control or humidistat, timer and pullcord. All models are also available in SELV (Safety Extra Low Voltage).
Complies with Building Regulations Part L 2010:
Low energy consumption means the Tempra exceeds the energy saving requirements in Part L, Conservation of Fuel and Power.
Switching on/off or from trickle to boost speeds is possible in several ways: Switched Live, Pullcord or Humidistat. Overrun and delay start timers are also available.
The extract-only Summer Setting helps keep you cool by closing off the intake from outside, reducing the amount of warm air entering the dwelling.
Fits 100mm diameter hole:
The Tempra will fit 100mm through the wall applications as a straight replacement for a traditional extract fan.
Continuous or intermittent flow rates:
Air flows can be set to quiet, low speed continuous rates or high speed intermittent boost rates.
Low energy consumption, low noise:
The unique twin impeller design consumes as little as 2.0 Watts and operates almost silently on trickle setting.
Long Life ECDC Motor:
The units are fitted with a 24V ECDC motor with a state of the art built in power supply. This has the ability to operate at only 2 Watts power consumption on normal setting, offering a 90% energy saving over conventional AC equivalents
Apart from removing odours, providing fresh air and recovering heat, this appliance extracts airborne impurities such as dust, dirt and grease. These gradually build up and detract from the efficiency and appearance of the appliance. To ensure peak performance, the heat exchanger should be cleaned as required in accordance with the instructions supplied.
The Lo-Carbon Tempra unit is designed for installation in a 102mm (4”) core drilled hole. All installation can be carried out from inside the building. The units are suitable for external walls up to 318mm thick.

Hi, what are the dimensions of the rectangular body of the unit and what is the length of the duct?
Thank you for posting your question on i-sells.co.uk for the VENT AXIA LO-CARBON TEMPRA P (VEN443312)
I have updated the listing with an image showing the full dimensions. This can be viewed on either the main product listing or directly by clicking this link.
Please note that a longer version of the Tempra (VEN403832) is available for walls with a thickness of 321mm-460mm. I have also added dimensions for the long version.
Please let me know if there is anything else you would like to know about either unit or if you require any advice.
How close can this fan be sited to a domestic combination boiler balanced flue outlet? I only have a small area of external wall to vent through which has to accommodate both. Thanks.
Thank you for your question. The distance between a gas boiler horizontal outlet from the fan outlet is 600mm. If you require any further information please do not hesitate to give me a call on 0208 463 9683
are there mains voltage and low voltage options available for this model?
Thank you for your question. Yes this unit comes in mains and SELV the codes for these two units are. 443312&444368.
If I can help any further please do not hesitate to contact me on 0208 463 9683
Is this suitable for a ducted application, duct length approx 2 m.
Hi My wall is only 250mm thick, is it ok to have the flue sticking out By how much? Does it come with manual control switch for speed?
The minimum length of the duct is 320mm so there would be an extra 70mm of exposed duct in a 250mm wall. The fan is a pull cord version so does not require any other control.
Hi Can this be fitted directly above bath, shower. If not how far away it needs to be? Thanks
This system should not be located in zone 1 above or in the shower or above the bath, for that you should look at the Lo-carbon Tempra SELV versions
Hi can this unit be fitted in the basement ? Dose this unit circulates the air? Thank you
