Windvent SV

The Midtherm Windvent SV unit delivers the benefits of a combined air input and extract system, with the addition of an integral solar driven fan to increase air velocity on totally still summer days. The fan is powered by energy generated from the PV panels, built into the terminal roof, thereby minimising its carbon footprint. 

Research has shown that an active stack system is preferable if climatic conditions are unfavourable or in buildings prone to high summer temperatures (due to having to keep doors, windows or skylights closed for health, safety or security reasons), therefore creating undesirable internal thermal and environmental conditions for the building occupants. 

The pleasant increase in internal air velocities provided by the Windvent SV succeeds in boosting the potential of existing Windvent technology while utilising renewable energy and ensuring a comfortable working environment for occupants.


Why choose Solar-Vent?

The Solar Vent unit offers a low carbon footprint and therefore has little impact on the environment. All components have a 12 month parts and labour guarantee. 
Extended warranties are available for specific projects.

Technical Information

Windvent SV terminals house a fan to provide supplementary air. This fan is powered naturally by the solar panel situated on the lid of the Windvent. The PV solar panels capture solar energy which is then converted to electricity to power the fan’s battery via the internal charge controller unit. 


The addition of a fan transforms the passive stack terminal into an active stack unit where supplementary air can be forced into the system as necessary, to boost effectiveness in adversely still climatic conditions. 


Prolonged periods without sun can be simply over come with the provision of our mains battery back-up unit. These units monitor the battery’s condition on a daily basis and can be switched to low tariff night time charging thus ensuring the optimum condition, ready for the day ahead. 


Windvent SV units range in size from 600mm to 1500mm and are available as either square or circular shaped terminals and are powder coated to the standard RAL colours of your choice giving a high colour finish for many years.
