Pax Passad 31, with backdraught shutter*, is installed in ducts that do not have a natural draught (external wall). Used primarily as reinforcement for ventilation in homes with another existing system for basic ventilation, e.g. mechanical exhaust ventilation (but via own duct). The fan starts via adjustable presence sensor, or when the moisture level exceeds the set value.
* NB: A backdraught shutter is immediately harmful if the fan is installed in a ventilation duct with natural draught (for example in ceilings).
Experience and smart technology
We have developed the Pax Passad series so you can easily find a model that ensures ventilation in your home.
A Pax Passad fan is primarily intended to amplify the exhaust air flow in homes with natural ventilation. They are very simple both to install and use. Enough space in the frame part helps the installer’s job and cleaning is done with one simple operation, without any need for tools.
The fans’ smart functions give you care free ventilation and automatically help your house to “breathe” when it is needed most. The result is an indoor environment that makes both you and the house feel good!
The distinguishing features for all fans in the Pax Passad series are that they are extremely quiet, highly efficient, made from environmentally friendly material and have negligible energy consumption. The fans are obviously approved for installation in wet areas.
